As we approach the midpoint of the season, the playoff races in both leagues are as muddy as ever. With July just around the corner and the trade deadline looming, the teams on the fringes of the postseason picture need to figure out if they’re truly contenders or if they need to start looking toward the future.

Last year, we revamped our power rankings using a modified Elo rating system. If you’re familiar with chess rankings or FiveThirtyEight’s defunct sports section, you’ll know that Elo is an elegant solution that measures teams’ relative strength and is very reactive to recent performance. To avoid overweighting recent results during the season, we weigh each team’s raw Elo rank using our coin flip playoff odds (specifically, we regress the playoff odds by 50% and weigh those against the raw Elo ranking, increasing in weight as the season progresses to a maximum of 25%). The weighted Elo ranks are then displayed as “Power Score” in the tables below. As the best and worst teams sort themselves out throughout the season, they’ll filter to the top and bottom of the rankings, while the exercise will remain reactive to hot streaks or cold snaps.

First up are the full rankings, presented in a sortable table. Below that, I’ve grouped the teams into tiers with comments on a handful of clubs. You’ll notice that the official ordinal rankings don’t always match the tiers — there are times where I take editorial liberties when grouping teams together — but generally, the ordering is consistent.

It was an exciting weekend of baseball, with nine series ending in a sweep, but that was all overshadowed by the unexpected trade of Rafael Devers on Sunday night.

As June gets underway, the American League playoff picture is as muddy as ever — 12 teams are within 4 1/2 games of a playoff berth right now. Meanwhile, in the National League, there’s a pretty clear line between the haves and the have-nots, but even if the playoff picture isn’t as crowded, the races should provide plenty of drama this summer.

…

The Tigers and Cubs battled through a competitive and entertaining series last weekend, with Detroit taking two of the three games. It’s far too early to call this a World Series preview, but it’s certainly a possibility with the way these two teams are playing. The Tigers went 4-3 in their week of games against the two Chicago clubs, and their bullpen blew leads in all three of their losses. For now, this seems like more of a blip than a true concern — the Detroit bullpen ranks sixth in the majors with a 3.30 ERA and a 3.29 WPA, even if the peripherals (3.81 FIP, 3.71 SIERA) aren’t quite as strong — but it’s something to monitor as the season progresses.

The Mets split their NLCS rematch against the Dodgers in Los Angeles last week, with three of the four games being decided by one run, and then went to Colorado and swept the hapless Rockies. Pete Alonso was a one-man wrecking crew; he blasted five home runs and now has 17 on the season. New York has gone 12-3 since falling to three games out of first place with a loss on May 23, and as the Phillies continue to struggle, the Mets begin this week ahead 4 1/2 games in the NL East.

In their first matchup against the Red Sox this season, the Yankees lost two of the three games and allowed 27 runs in the series. Earlier in the week, New York placed closer Luke Weaver on the injured list with a hamstring strain, but the team did get back dynamic infielder Jazz Chisholm Jr.. After missing over a month with an oblique injury, Chisholm went 8-for-21 with two home runs and three stolen bases.

It’s been a rough couple of weeks for the Dodgers. They’re 10-12 over their last 22 games and neither their offense nor their pitching can find much consistency right now. Los Angeles collected 19 total hits in its first two games against the Cardinals last weekend but somehow managed to score just a single run, going 1-for-25 with runners in scoring position. The Dodgers salvaged the series with seven runs on Sunday in a 7-3 win, but their bats are still having a relatively rough go of things since their 18-run outburst against the Yankees the previous Saturday. The concerns about their lineup pale in comparison to the injury woes of their pitching staff, as Tony Gonsolin became the latest pitcher to go down with elbow discomfort. The good news is the Dodgers activated relievers Michael Kopech and Kirby Yates off the IL last weekend and spun an under-the-radar trade for former All-Star closer Alexis Díaz, whom the Reds optioned to Triple-A after a disastrous April. While the Dodgers are letting Díaz work things out in the minors before recalling him, the returns of Kopech and Yates should help to bolster the bullpen; the starting rotation, though, is still spread dangerously thin. Things won’t get any easier for the Dodgers this week, when they face the Padres and Giants for the first time this season. Both teams are just a game behind Los Angeles in the NL West standings.

The Astros have gotten hot at exactly the right moment. Their surge has coincided with a Mariners slide; Houston overtook Seattle in the AL West standings in late May and padded the lead last week. The Astros have gone 11-5 over their last 16 games, a stretch that began with taking three of four from Seattle, and are now 2 1/2 games up in the division. Jeremy Peña continues to lead the offense during this hot streak; he collected 10 hits last week and had a 13-game hit streak snapped on Sunday.

The Rays and Blue Jays continued their rise up the standings last week; Tampa Bay swept the Rangers and won two out of three against the Marlins, while Toronto took both of its series against the Phillies and Twins. In 16 games since May 23, Rays third baseman Junior Caminero is slashing .349/.388/.825 with seven home runs and a 242 wRC+. A resurgent George Springer, who smacked a game-winning home run on Saturday, has been the most consistent run producer in the Blue Jays lineup.

The Giants tallied two more walk-off victories last week, bringing their season total to eight. All seven games of their games last week were decided by one run, and they haven’t played a game that was settled by more than three runs since May 23. San Francisco is now 22-11 in home games this season, one of the best home records in baseball. After a 5-2 homestand, the Giants return to the road with a 38-28 overall record, which puts them just a game behind the first-place Dodgers in the NL West.

The Phillies are phree-phalling right now, with just one win in their last 10 games. That lone win came in their series opener against the Blue Jays last Tuesday, and then over the weekend they were swept by the last-place Pirates. The Philadelphia offense went especially cold, managing to score just one run in four of its last five games. To make matters worse, Bryce Harper was placed on the IL with a wrist injury over the weekend, though it sounds like it might be a minor issue.

Injuries have become an issue for the Twins again, only this time, it’s in their starting rotation. Both Pablo López and Zebby Matthews were placed on the IL last week with shoulder injuries; López is expected to miss at least two months, while it’s unclear as of this writing how long Matthews might be out. Thankfully, Royce Lewis is healthy and snapped an 0-for-28 stretch with a hit on Tuesday, and then notched six more after that.

The three teams in this tier all feature flawed lineups with no more than one or two superstars who are tasked with putting the rest of the offense on their backs. The Guardians couldn’t handle the Yankees and Astros last week, though José Ramírez continued to rake. He carries a 34-game on-base streak into Monday’s series opener against the Reds, and he has at least one hit in all but two of those games. Overall, he’s slashing .333/.392/.556 with 12 home runs, 18 stolen bases, and a 163 wRC+. Meanwhile, Bobby Witt Jr. is catching fire after a so-so month of May; though the Royals went just 3-3 last week, Witt brought his season wRC+ up to 126 after going 9-for-25 with two homers. Kansas City also called up top prospect Jac Caglianone last week to bolster what has been one of the worst offenses in baseball. Seattle had a rough week, getting swept by the Orioles and losing two of three against the Angels, but Cal Raleigh bashed three more home runs, extending his major league-leading total to 26.

It was the worst-case scenario for Corbin Burnes and the Diamondbacks. First, the ace left his June 1 start with an elbow injury, and then on Friday, Arizona announced he would undergo Tommy John surgery. He’ll miss the rest of the season and most likely all of 2026 as well. It’s a deflating blow to a club that’s been struggling to keep up in the extremely competitive NL West. The rotation has had its fair share of troubles this year, and Burnes’ injury is the biggest one yet.

In a wide open AL playoff picture, it’s not too late for the Rangers to get back into the race, especially if their offense starts to click. To that end, after an abysmal start to the season, Marcus Semien is 15-for-29 with three home runs and a 324 wRC+ over his last nine games. Let’s see if his teammates follow his lead and start mashing this week, when Texas visits Minnesota for three games before returning home to face the White Sox over the weekend.

However, it probably is too late for the Orioles to recover from their disappointing first two months, but at least they’re playing much better baseball recently. They lost their weekend series to the Athletics, but before that, they had gone 9-2 over their previous 11 games. They activated Colton Cowser off the IL last Monday and should be getting Jordan Westburg back from his hamstring injury any day now.

It might be time to admit that it’s just not the Braves’ year. They were swept by the Diamondbacks and the Giants last week, and their seven-game losing streak has dropped them to 14 games back in the NL East and 9.5 games back in the NL Wild Card standings. On Thursday, they blew a six-run against Arizona in the top of the ninth inning, and then lost back-to-back walk-offs against San Francisco on Friday and Saturday. More concerning has to be the ongoing struggles of Spencer Strider; he lost his two starts last week, both his ERA and FIP are up over five, and his Stuff+ is down about 20 points from his last healthy season in 2023.

The Athletics snapped out of a month-long tailspin with a series win over the Orioles last weekend. The A’s peaked on May 5 when they walked off Seattle and pushed their record to 20-16. After that, they lost 24 of their next 27 games before finally beating the Twins 14-3 on Thursday, exactly one month after the high point of their season. During that 3-24 stretch, they allowed 7.8 runs per game, by far the worst mark in the majors.

Not only did the Rockies finally win a series last week, they secured a three-game sweep of the Marlins! It was their first series win since September of last year and the first time they had won more than two games in a row this season. That winning streak was quickly snapped, when the Mets swept Colorado at home over the weekend. The Rockies are a truly terrible team, no matter how hard Davy Andrews tries to make them look good, but for the sake of all the loyal fans who somehow still show up to their games, hopefully last week’s series won’t be the only one they win in 2025.

The calendar has flipped to June, and the teams that are fighting for their place in the playoff picture are starting to get serious about addressing the flaws on their rosters.

We’re almost through the first two months of the season, and playoff races in both leagues are shaping up to be pretty entertaining this summer. All but three teams in the AL are within three games of a postseason berth, which makes for a very crowded field. The NL is a little more stratified, but there are four Wild Card hopefuls hanging four or five games back in the standings.

The Reds rotation has been an undeniable strength this season. The team’s starters are third in park- and league-adjusted ERA, and their collective peripherals mostly back it up; they’re 10th in park- and league-adjusted FIP. Hunter Greene has been phenomenal, Nick Lodolo has made some key command improvements, and Brady Singer has added a secret ingredient, though his ERA has ballooned to over 5.00 since Michael Baumann wrote about him last month. But the pitcher leading the team in ERA is Andrew Abbott, and before Baumann can write about his third Cincinnati starter this year, I’d like to take a stab at puzzling out what’s gone right for the 25-year-old lefty.

What if I told you that while Abbott’s fastball is coming in about a tick slower than normal and his arm slot is five degrees higher than usual, he has somehow managed to slightly improve the pitch’s Stuff+ score? You might be a bit confused, as the trend for many pitchers has been to try and lower their arm slot in an effort to flatten out their four-seamers. A flatter approach angle often leads to more swings and misses at the top of the zone and weaker contact, as batters have trouble squaring up a pitch that looks like it’s rising above their bat. Abbott has always had a high release point, but his 50 degree arm angle is now the 11th-highest arm slot among qualified left-handed pitchers.

Research into the relationship between a pitcher’s arm slot and the shape of their pitches has shown that as a pitcher’s arm slot rises, they’re able to generate more backspin. More backspin allows them to create more induced vertical break (IVB). Put simply, IVB is a function of arm angle. The other thing about a high arm angle is that purer backspin fastballs tend to cut less horizontally. Abbott has managed something somewhat tricky with his new arm slot:

Despite the higher release angle, Abbott hasn’t experienced a corresponding increase in the amount of carry on his heater. The other odd thing is that he’s been able to maintain the higher-than-normal horizontal break he generates with the pitch. Because he’s now throwing from a higher slot, the pitch has a much steeper approach angle, and the pitch’s cutter-esque shape provides a wider horizontal approach angle.

Abbott’s four-seamer now stands out both because it doesn’t carry as much and because it cuts more than you’d expect. A “dead zone” fastball describes a pitch with unspectacular movement traits — a fastball that moves as expected. Research has shown that a fastball’s dead zone is a function of the pitcher’s arm angle, leading to the concept of a dynamic dead zone (DDZ). Using Alex Chamberlain’s calculated DDZ deltas (based on work done by Max Bay), we can see just how much Abbott’s fastball falls outside of what the batter expects based on his arm slot:

Remember, magnitude is what matters when evaluating a pitcher’s DDZ, so Abbott’s negative vertical dead zone delta isn’t necessarily a bad thing, though his +2.8 horizontal dead zone delta is very much a good thing.

The results have been positive so far. His whiff rate on the pitch has improved from just over 19% during his first two seasons to 25.2% this year. The additional swings and misses are nice, but he’s also turned his heater into a contact-suppression monster. Just look at some of these key contact metrics from Statcast:

Abbott’s expected wOBA on contact when he throws his fastball is just .297, 17th among the 248 pitchers who have thrown at least 100 four-seamers this year. The hard-hit and barrel rates against the pitch are miniscule. The most impressive aspect of his contact management comes from Statcast’s new bat tracking data. Opposing batters produce the second-highest average bat speed in baseball against Abbott’s fastball, but they “square-up” the pitch at the third-lowest rate on a per swing basis and they produce a “blast” against his heater at the fourth-lowest rate in baseball. In other words, batters really gear up when they see Abbott’s fastball because their eyes are telling them that the pitch is very hittable, but they simply cannot make solid contact against it.

To connect this all back to the pitch’s shape, I expect that this contact suppression is all linked to the amount of horizontal break Abbott generates with his fastball. With his high arm slot, a batter expects to see a straight four-seamer with tons of carry. Instead, they’re presented with a cutting fastball that doesn’t have as much carry as you’d expect. Rather than swing completely under the pitch like they might if it had a ton of carry, they’ll often put it in play, but it’s weak contact because the pitch doesn’t come in where they expect it to horizontally. So much of the contact he generates with the pitch is off the end of the bat or in on the handle, leading to weak fly balls and popups.

Of course, location matters, too. In the first table above, I included average vertical location, because location is a critical component of vertical approach angle. Abbott is locating his fastball much lower in the strike zone this year, which, along with his higher arm slot, has contributed to his steeper approach angle. He’s also been very consistent with his location on the outer half of the plate to right-handed batters:

Because the horizontal break on the pitch causes it to tail away from righties, his location is perfect for inducing weak contact off the end of the bat while avoiding the barrel if it ends up over the heart of the plate.

In case you were worried about Abbott’s dip in velocity, I’m happy to report that his heater has had a bit more zip during his last few starts:

A shoulder injury last August cut short his 2024 season, and he entered spring training a little bit behind schedule because of it. I suspect that he was still ramping up during his first few starts of the season and that his velocity will be back to normal moving forward.

Beyond his fastball and the new arm slot, there’s one key change to the rest of Abbott’s repertoire that could be contributing to his success. He’s getting about three more inches of drop on his changeup while still maintaining the pitch’s above-average horizontal break. The whiff rate on that pitch has improved by about four points, and the expected wOBA against it is just .222. More importantly, the change in shape has allowed him to differentiate the pitch from his fastball a bit more:

Please excuse the color differences from year to year in the plots above. In Abbott’s pitch plot from 2024 on the left, his changeup (the black blob) somewhat overlaps with his fastball (the blue blob). In 2025, on the right, his offspeed pitch (the green blog) is wholly distinct from his heater (the blue blob).

Abbott briefly discussed the evolution of the pitch with Charlie Goldsmith of the Dayton Daily News in late April:

It’s come a long way. I talked with Nick Martinez and a bunch of the guys about how to throw it, grips and all of that stuff. It’s finally coming around. It’s not to where I think it can be yet, but it’s gotten a lot more consistent.

He has increased his use of his changeup from 16.3% last year to 21.3% this year, and it has proven to be a potent weapon against right-handed batters.

With a new arm slot, a deceptive fastball, and an improved changeup in hand, Abbott has truly elevated his arsenal. His walk rate is a little high right now, but his strikeout rate is 30.3%, and the contact suppression improvements he’s made to his heater have almost entirely negated those additional free passes. The top-line results certainly speak for themselves: Abbott has allowed more than one run in just one of his starts this year, and that happened to be the only start in which he’s allowed more than four hits. As long as batters are unable to square up his fastball, we could be seeing a significant step forward from the young lefty.

Thanks to a big upset during MLB’s inaugural Rivalry Weekend, the Dodgers are out of the top spot in these rankings. In their place? The Gritty Tigs.

We’re now a quarter of the way through the regular season, and even though the playoff races have largely taken shape, there’s still plenty of time for some of the early disappointments to get things right. Last week, it was the Twins and Cardinals who caught fire with matching eight-game winning streaks.

…

The Dodgers split a big four-game series against the Diamondbacks last weekend, and Friday night’s game was an especially wild affair. There were four lead changes, and Los Angeles won after scoring six runs in the ninth inning, a rally that was capped off by a go-ahead three-run bomb from Shohei Ohtani, his fourth home run of the week. Freddie Freeman also hit four homers last week and collected 10 other hits. The Dodgers’ roster was depleted even further when Teoscar Hernández and Evan Phillips hit the IL on Tuesday — they now have 15 players on the IL — but they’ve continued to prove they have enough talent to maintain their spot as the top team in baseball.

The Mets took two out of three games in both of their series last week, but the Phillies did them one better, going 5-1 on their roadtrip through Tampa Bay and Cleveland. Suddenly, the NL East looks very tight at the top. New York is still in first place, but its hold on the division is now just 1.5 games, down from five as recently as April 26. The good news for the Mets is that, even as that gap has narrowed, Juan Soto’s bat has woken up; he blasted three home runs last week, the same amount he hit in all of April, and he’s up to five dingers since the calendar flipped to May. The Mets have a big subway series against the Yankees lined up for this weekend as they try to cling to their division lead. Meanwhile, the Phillies return home to host the surging Cardinals before the Pirates come to Philly for an intrastate rivalry series over the weekend.

So far, the Cubs have faced the toughest schedule in the majors by a pretty significant margin, which makes their 23-18 record all the more impressive. Thankfully, they won’t face another opponent with a record over .500 until early June, as their series against the Marlins, White Sox, Reds, and Rockies will take them through the rest of the month. Chicago was already without Justin Steele and Javier Assad when Shota Imanaga landed on the IL with a hamstring strain early last week. In response, the team called up its top pitching prospect, Cade Horton, to make his major league debut over the weekend, using him as the bulk guy in Saturday’s 6-5 win over the Mets. The easier schedule should alleviate some of the pressure on the patchwork rotation, though the Cubs will definitely want to find some reinforcements before the dog days of summer set in.

The Yankees snapped the Padres’ six-game winning streak on Tuesday, though San Diego got back on track with two wins against the Rockies over the weekend, including a 21-0 drubbing on Saturday. As for New York, the offense carried the team through two series wins last week. Aaron Judge went hitless in two games early in the week but got his bat going again against the A’s in Sacramento. He blasted two home runs on Saturday and collected four hits on Sunday, pushing his batting average back over .400. He enters Monday’s series opener in Seattle slashing .409/.494/.779 with 14 home runs, a 254 wRC+ and 3.8 WAR.

Speaking of the Mariners, their streak of nine consecutive series wins was snapped over weekend when they were swept at home by the Blue Jays. They’re still leading the AL West, but they have two difficult series ahead of them this week: the aforementioned matchup with the Yankees, followed up a three-game set in San Diego.

Over in the AL Central, the Tigers continue to hold onto the best record in the AL, but they dropped their weekend series to the Rangers. The Royals entered their weekend series against the Red Sox on a seven-game winning streak with five straight series wins before Boston’s pitching slowed them down. Kansas City lost on Saturday and Sunday and was held to just one run in each game.

The Cardinals and Twins are the hottest teams in baseball right now, with each club carrying eight-game winning streaks into the new week after struggling over the first month of the season. Ten days ago, St. Louis was six games out of first place and five games under .500; now the club is just a game behind the Cubs in the NL Central. Pitching has led the way for the Cardinals during their ascent, as they allowed a total of seven runs last week. Matthew Liberatore’s long-awaited breakout is the big story; he outpitched Paul Skenes in a seven-inning gem on Tuesday, giving up one run while striking out eight.

Meanwhile in Minnesota, Royce Lewis and Willi Castro were both activated off the IL last week, giving the roster a much needed boost. Likewise, it’s the pitching that’s driving their success; the Twins held opponents to two or fewer runs in their first five games last week before Sunday’s 7-6 walk-off win over the Giants. The offense still hasn’t really clicked, but their excellent run prevention has allowed them to post a +19 run differential despite sitting just a game over .500. Unlike the Cardinals, though, the Twins are still in fourth place and five games out of first because the AL Central — featuring the Tigers, who have the best record in the AL, as well as the Royals and Guardians — is one of the most competitive divisions in baseball.

In the wake of Triston Casas’s season-ending knee injury, the Red Sox unnecessarily walked into another ugly spat with their franchise cornerstone last week, when chief baseball officer Craig Breslow asked Rafael Devers if he would be open to playing first base. It’s not an outrageous ask from a baseball perspective, but the problem is the lack of clear communication, both public and private, between Boston’s front office and its most important player. Thankfully, none of this has affected Devers at the plate; he collected 10 hits last week, including two home runs, and his season wRC+ is now up to 146.

The Astros placed Yordan Alvarez on the IL early last week with some inflammation in his hand. Then, on Saturday, Jose Altuve exited the game early with hamstring tightness. Neither injury is considered serious, but it’s just another hurdle Houston has to overcome this year. The Astros are virtually tied with the Athletics in the AL West standings, two games behind the Mariners and a game ahead of the Rangers. Both Texas teams went 3-3 last week, while the A’s dropped both their series against the Mariners and Yankees.

The Cardinals’ hot streak has pushed the Brewers and Reds down a notch in the NL Central standings. Jackson Chourio is clearly talented, but his hyper-aggressive approach this season has led to inconsistent results. He’s supposed to be leading Milwaukee’s offense, but no one is really hitting right now. The pitching has been good considering all the injuries the staff has had to overcome — Brandon Woodruff and Aaron Civale are both nearing their returns — but a team that can’t score runs consistently won’t go anywhere.

For Cincinnati, a rash of injuries has derailed any success the team might have enjoyed earlier in the season. Hunter Greene, Noelvi Marte, and Jake Fraley all hit the IL last week, though thankfully Austin Hays returned from his own injury on Friday. After the Reds had scored just 10 runs across their previous six games, they erupted for 13 runs against the Astros on Saturday. Of course, they were shut out a day later; their offensive woes won’t be solved that easily.

After getting swept by the Twins, the Orioles bounced back with a series win against the Angels last weekend. If you’re looking for signs of hope, Zach Eflin was activated off the IL on Sunday and looked pretty good in a five-inning outing. On the offensive side of things, Jackson Holliday is showing some signs of life; he’s collected a pair of home runs and nine hits this month.

Both the Pirates and Rockies fired their managers last week, though neither Derek Shelton nor Bud Black were to blame for the struggles of their respective teams. Instead, the two managers are just the latest scapegoats for two beleaguered franchises going nowhere. At least Pittsburgh has some excellent pitching to witness every few days, with some more exciting prospects on the way. The situation in Colorado is much more bleak. The Rockies allowed a whopping 66 runs last week. On Thursday, they lost both games of a doubleheader by a combined score of 21-3, and somehow things got worse from there — they needed only one game on Saturday against the Padres to surrender 21 more runs. Final score: 21-0. Ouch.

The calendar has flipped over to May, and a handful of teams have jumped out ahead in the standings. Behind them sit a huge mass of mediocre ballclubs all jostling for position but struggling to stand out in one way or another.

Last year, we revamped our power rankings using a modified Elo rating system. If you’re familiar with chess rankings or FiveThirtyEight’s defunct sports section, you’ll know that Elo is an elegant solution that measures teams’ relative strength and is very reactive to recent performance. To avoid overweighting recent results during the season, we weigh each team’s raw Elo rank using our coin flip playoff odds (specifically, we regress the playoff odds by 50% and weigh those against the raw Elo ranking, increasing in weight as the season progresses to a maximum of 25%). The weighted Elo ranks are then displayed as “Power Score” in the tables below. As the best and worst teams sort themselves out throughout the season, they’ll filter to the top and bottom of the rankings, while the exercise will remain reactive to hot streaks or cold snaps.

First up are the full rankings, presented in a sortable table. Below that, I’ve grouped the teams into tiers with comments on a handful of clubs. You’ll notice that the official ordinal rankings don’t always match the tiers — there are times where I take editorial liberties when grouping teams together — but generally, the ordering is consistent. One thing to note: The playoff odds listed in the tables below are our standard Depth Charts odds, not the coin flip odds that are used in the ranking formula.

…

The Dodgers had their seven-game win streak snapped on Sunday night, but that surge gave them the best record in baseball and a half-game lead over the Padres in the NL West. However, for as well as they’ve played this season, the Dodgers still have their issues, especially on the injury front. Last week began with Tyler Glasnow landing on the IL with shoulder inflammation — he was shut down from throwing for 10-14 days, and the Dodgers are expected to be cautious with him as he works his way back — and then Tommy Edman followed him a few days later after he hurt his right ankle on a slide. It’s the same ankle that Edman sprained last year while he was recovering from offseason wrist surgery and delayed his season debut until August; he did not sprain it this time around, and the Dodgers expect him to return as soon as he’s eligible to come off the IL on Saturday. The lineup hardly skipped a beat without the surprisingly powerful switch-hitter; Los Angeles put up double-digit runs in three games last week.

The Cubs won both of their series against the Pirates and Brewers last week, beating up on some division rivals and pushing their lead in the NL Central to three games, the largest in baseball. They could be facing some more injury trouble as Shota Imanaga exited his start on Sunday with a hamstring injury. Not to be outdone, the Padres completed a perfect week with five straight wins. That streak got San Diego back on track after a pretty poor end to April. On the flip side, the Mets lost both of their series last week.

The Mariners’ ascent has continued despite some choppy seas. Not only did they lose Logan Gilbert to a minor forearm injury, but Luke Raley and Dylan Moore joined him on the IL last week, sapping the lineup of two key contributors. No matter, because Jorge Polanco is doing his best Aaron Judge impression, Cal Raleigh is leading the league in home runs, and role player Leo Rivas is enjoying some surprising success (182 wRC+ in 15 games). More importantly, key setup man Matt Brash was just activated off the IL over the weekend after rehabbing from Tommy John surgery, and George Kirby made his first rehab start as he works his way back from a spring shoulder injury.

Javier Báez lives! The erstwhile shortstop made the transition from the infield to center field a few weeks ago and has suddenly thrived in the new role. He’s collected hits in every game he’s started at his new position. Last week, he clubbed home runs in three straight games and his resurgence is a big reason why the Tigers have maintained the best record in the AL.

The Phillies could use some bullpen help. On Tuesday, Orion Kerkering blew a save against the Nationals when he allowed four runs in the top of the ninth inning, though his offense picked him up with two runs in the home half to walk it off. Philadelphia wasn’t so lucky on Sunday. This time it was José Alvarado who gave up four runs — one in the ninth and three in the 10th — leading to an ugly extra-innings loss to the Diamondbacks. By league- and park-adjusted ERA, the Phillies have the sixth-worst relief corps in baseball right now. Even so, despite the bullpen woes, they’ve won six of their last eight games and enter this week just 2.5 games behind the Mets in the NL East standings.

The Giants are no longer in first place, though they’ve mostly kept pace with the surging Dodgers and Padres. San Francisco enters this week as the third-place team in the NL West, but the club is just 1.5 games out of first. That early-season success isn’t much of a mirage, either. The Giants’ actual record is just a game better than their Pythagorean record and two games better than their BaseRuns record. Meanwhile, it seems shortstop Willy Adames is finally heating up. Last week, he slashed .348/.483/.826 with three home runs and a 251 wRC+ in 29 plate appearances.

Last week was a bit of a mixed bag for the two NL teams in this tier, as both the Braves and Diamondbacks went 3-3 and maintained their places on the fringe of the playoff picture. Arizona salvaged its weekend series with a wild Sunday win over the Phillies to go along with a series win over the Mets. All eyes are on ace Corbin Burnes, who is skipping his start this week due to a sore shoulder. Atlanta, meanwhile, escaped Colorado with a series victory but lost two of three against the Dodgers over the weekend.

Aaron Judge can’t do it all. He extended his hitting streak to 14 games on Sunday — and on the season he has a ludicrous .423/.510/.777 slash line with 11 home runs, a 261 wRC+ and 3.4 WAR — but the Yankees lost both of their series last week to the Orioles and Rays. Luckily for New York, though, no one else in the AL East was able to take advantage of the hiccup; despite going 2-4 last week, the Yankees enter Monday’s series opener against the Padres with the same two-game lead that they held a week ago.

The Royals blasted seven home runs in their victory over the Orioles on Sunday; they had hit 18 total as a team heading into that contest. Following the barrage, they are now tied with the Pirates for the second-fewest homers in baseball. However, that lack of power hasn’t held them back over the last two weeks. Kansas City has won four straight series and is 11-2 during this stretch.

The Rangers fired offensive coordinator Donnie Ecker on Sunday, the second domino to fall after they demoted key offseason acquisition Jake Burger on Friday. Texas has lost five straight series and scored more than four runs just three times in its last 16 games, a truly miserable stretch. Meanwhile, the Athletics have become road warriors after going 5-2 on their latest trip — which included a huge series win over the Rangers — and pushing their record to 13-7 away from Sacramento. We’ll see if they can keep up their winning ways when they return home this week for series against the Mariners and Yankees.

The Blue Jays and Orioles each moved one game closer to the Yankees during New York’s skid last week, but the Red Sox and Rays failed to gain any ground after matching the AL East leader’s 2-4 record. Boston has to be a little worried about its mounting injury woes; as soon as the team welcomed back Lucas Giolito, it placed Walker Buehler on the IL with a shoulder injury. The bigger blow came on Friday, when first baseman Triston Casas ruptured his patellar tendon; he’s out for the season after undergoing surgery on Sunday.

The one saving grace for the Orioles last was the collective poor play from the rest of the AL East. They started the year with 48% odds to make the playoffs; they’re at 13.4% right now and time is growing shorter for them to turn things around. Baltimore’s series win over the Yankees at the beginning of last week could have been that turning point, but the O’s followed it up with a series loss to the Royals.

The Nationals have been on a quiet run of good play over the last few weeks. Despite going 3-3 last week, they’re 9-7 over their last 16 games. At the forefront are two guys they acquired in the big Juan Soto trade a few years ago. James Wood has pushed his wRC+ up to 157 after collecting eight hits last week, and MacKenzie Gore’s strikeout rate is now up to 36.4% on the season after striking out nine in another solid start on Sunday.

After starting the season with a promising 9-5 record, the Angels have won just four of their last 19 games. To make matters worse, Mike Trout landed on the IL with a bone bruise in his left knee. Prior to hurting his knee, Trout had been showing some good power — his nine home runs are tied for fourth in the AL — but his overall batting line (a 97 wRC+) left a lot to be desired.

A rain-shortened win over the Astros on Sunday gave the White Sox a rare series victory and their fifth win in their last 10 games. Amazingly enough, their run differential is just a single run worse than that of the Guardians, who are 10 games up on them in the standings. This little “hot” streak has pushed the South Siders ahead of their historically inept pace from last year, though they’re still tracking to lose well over 100 games this season.

The unpredictable nature of the early season has reared it’s head. You might have been able to guess that the Mets would have the best record in baseball after a month, but I doubt many would have foreseen the Tigers holding the AL’s best record entering the final week of April.

…

Tyler Glasnow made an early exit from his start on Sunday after experiencing some shoulder discomfort. That leaves the Dodgers with three healthy starters and a lot of questions about how they’re going to fill out their rotation. Tony Gonsolin is on track to be activated from the IL to make his season debut this week, but it’s still troubling how quickly Los Angeles burned through its pitching depth.

The Mets completed a perfect seven-game homestand last week that culminated on Wednesday with a walk-off victory to seal a sweep over the Phillies. Jeff McNeil and Francisco Alvarez were activated off the IL on Friday, and the young catcher blasted his first home run of the season in Saturday’s 2-0 win. New York currently owns the best record in baseball, but the team had some trouble handling the Nationals over the weekend, coughing up two late leads on Friday and Sunday.

The growth of Pete Crow-Armstrong at the plate to go along with his elite defense and baserunning has been a huge difference maker for the Cubs. He nearly singlehandedly won a two-game set against the Dodgers last week, collecting six hits, two home runs, and two stolen bases. His evolution is one of many reasons why the Cubs have the best offense in baseball through the first month of the season.

The Tigers won their third straight series with a sweep of the Orioles as the exclamation point over the weekend. They’re currently the best team in the American League thanks to a pitching staff that’s allowed the fewest runs in the league. Unlike last year’s surprising playoff club, Detroit’s starting rotation has been a strength, posting the second lowest park- and league-adjusted ERA in baseball. Tarik Skubal has obviously been the headliner, but the Tigers have gotten strong contributions from all five starters this season.

The Yankees salvaged what had been a rough week with a doubleheader sweep of the Blue Jays on Sunday. With those two victories, they maintained their two-game lead over the Red Sox in the AL East. Aaron Judge has been hitting at an all-time-great pace, even as he has only two home runs over the last two weeks. He enters this week with a .406/.500/.717 slash line, eight home runs, a 247 wRC+, and 2.7 WAR. Unlike some recent seasons, Judge is far from the only offensive force in the lineup; Cody Bellinger is the only Yankee with at least 50 plate appearance and a wRC+ below 100. That high-powered offense has covered up some bullpen woes. Devin Williams has had a rough start to his Yankees tenure; another blown save on Friday shot his ERA up to 11.25, and he’s been removed from the closer role until he can get things back on track.

The Mariners may have dodged a bullet on Friday, when Logan Gilbert was removed from his start after pitching just three innings. He was diagnosed with a Grade 1 flexor strain rather than anything more serious. As it is, he’ll join George Kirby on the IL, and suddenly Seattle’s stellar starting rotation looks a lot thinner than it has in a long time. Thankfully, the bats have stepped up. With a 126 wRC+, the Mariners currently boast the second-best offense in baseball, and Cal Raleigh and his major league-leading 10 home runs are a big reason why.

Don’t look now, but the Braves have won three straight series and seven of their last nine games, putting them just three games under .500. It’s been quite a turnaround from their 0-7 start, though they’re not out of the woods yet. After making just one start this season, Spencer Strider returned to the IL last week with a hamstring strain. It should be about a month before Atlanta welcomes back both the ace and Ronald Acuña Jr., who is ramping up but has yet to begin a rehab assignment.

The Phillies snapped a five-game losing streak with a win on Saturday over the Cubs and backed it up with an extra-innings victory on Sunday night. There’s considerable daylight between them and the Mets atop the NL East — four games is the largest division lead in baseball — though it’s far too early to panic in Philadelphia. Encouragingly, Aaron Nola spun a seven-inning gem in his start on Sunday to snap out of his early-season funk.

The Rangers dropped their third straight series over the weekend in ugly fashion, losing Sunday’s rubber match with the Giants when Heliot Ramos led off the ninth and hit a walk-off dribbler back to the pitcher, courtesy of two throwing errors. It was their third walk-off loss of the week. Their vaunted offense has scored the fewest runs per game in the majors this season. The scorching starts of Wyatt Langford (215 wRC+) and Josh Smith (148) have been offset by the woes of Jake Burger (46 wRC+), Marcus Semien (25), and Joc Pederson (13). Making matters worse, Corey Seager (133 wRC+) landed on the IL last week with a right hamstring strain, though he’s not expected to miss much more time than the minimum 10 days.

The Rays bounced back nicely last week, winning a series in Arizona before sweeping the Padres in San Diego. Both of their victories against the Diamondbacks came in extra innings, and the pitching staff held the Friars to just three runs in three games. Maybe getting out of Tampa was exactly what they needed to give them a spark — that and Chandler Simpson running wild in center field and on the basepaths.

The Reds swept the Rockies over the weekend and now have a modest four-game winning streak going. The pitching has continued to impress and Elly De La Cruz is starting to heat up; he’s riding an 11-game hit streak. More importantly, he’s getting support from elsewhere in the lineup. Noelvi Marte collected 10 hits last week, including two home runs, and with a 221 wRC+ in 12 games (54 plate appearances), Austin Hays has provided a jolt to the offense since making his season debut on April 15.

The Orioles’ struggles have continued unabated. It’s not just their starting rotation, either. There was some hope that the offense would be able to carry the load until Zach Eflin or Grayson Rodriguez returned. Unfortunately, the lineup scored just 10 runs in six games last week, and key contributors like Gunnar Henderson, Adley Rutschman, and Jordan Westburg have gone cold. Cedric Mullins is essentially carrying the offense by himself. Baltimore has a critical three-game series against the Yankees this week, and it could be a bellwether for how the rest of this season is going to go.

The Marlins called up Agustín Ramírez on Monday and he promptly clubbed nine hits, three home runs, and four doubles during his first week in the big leagues. Miami’s offense as a whole hasn’t been all that bad, just a bit below league average. Rather, it’s the pitching that has let the team down. Max Meyer’s breakout has been great to see, but the rest of the starting rotation has been a mess, and the bullpen has been one of the worst units in baseball.

It’s probably too early to think about the Rockies “besting” the historically bad season the White Sox endured last year, but it’s the end of April and Colorado has won just four games. Things have been so bad that even when something exciting happens — like Jordan Beck’s five home runs in the span of two days last week — the team still finds a way to lose.
