While Bryce Harper made the quickest return from Tommy John surgery of any position player on record, it came with a cost. Not surprisingly, he didn’t hit the ball as hard as usual in the early months of his return, or do as much damage because he wasn’t elevating it with consistency. At one point, he went 166 plate appearances without a home run, the longest drought of his career, but even then, he remained a reasonably productive hitter. Lately he’s been heating up, crushing the ball while helping the Phillies climb to the top of the NL Wild Card race.

In the fourth inning of Monday night’s game against the Angels in Philadelphia, Harper demolished a Lucas Giolito fastball that was playing in the middle of the road:

The homer — a 111.9-mph scorcher with a projected distance of 429 feet — was Harper’s fourth in a seven-game rampage, during which he’s hit .500/.613/1.037. It was his eighth homer of the month, his highest total since he hit nine in September/October 2021 (and 10 in August of the same season) en route to his second MVP award. He maxed out at seven homers in May of last season, the month he was diagnosed with a torn ulnar collateral ligament in his right elbow. Read the rest of this entry »

2:02	Jay Jaffe: Good afternoon folks, and welcome to the last August edition of my chat for 2023!

Jay Jaffe: anyway, yesterday I ran a piece on Félix Bautista’s UCL injury https://blogs.fangraphs.com/a-great-summer-ends-with-a-bummer-as-the-o…. Still no word on the severity of it, but I wouldn’t really read into that as good news. The Orioles aren’t the most transparent bunch when it comes to injuries or… other matters

Some of the most frustrating arguments involving baseball statistics revolve around the use of expected stats. Perhaps the most frequently cited of these metrics are Statcast’s xStats, which use Statcast data for hitters to estimate the batting average, on-base percentage, slugging percentage, and wOBA you’d “expect” a hitter to achieve. Investigating how predictive xStats are compared to their corresponding actual stats has been a common research exercise over the last few years. While it depends on the exact dataset used, xStats by themselves generally aren’t much better than the actual stats at predicting the next year’s actual stats. But that doesn’t mean we should simply discard expected stats when trying to evaluate players.

While I’m not going spend too much time talking about how predictive xStats are versus the actual ones, I do want to briefly touch on some of the existing work on the subject. Jonathan Judge at Baseball Prospectus examined many of the expected metrics back in 2018. He also spoke with MLBAM’s Tom Tango about the nature of expected stats and their usage:

Earlier this week, we reached out to BAM with our findings, asking if they had any comment.

MLBAM Senior Database Architect of Stats Tom Tango promptly responded, asking that we ensure we had the most recent version of the data, due to some recent changes being made. We refreshed our data sets, found some small changes, and retested. The results were the same.

Tango then stressed that the expected metrics were only ever intended to be descriptive, that they were not designed to be predictive, and that if they had been intended to be predictive, they could have been designed differently or other metrics could be used.

Gavin Stone was credited with his first big league win on Sunday. Working in a bulk role behind opener Caleb Ferguson, the 24-year-old rookie right-hander went six solid innings as the Los Angeles Dodgers topped the Boston Red Sox 7-4 at Fenway Park. His changeup played a predictably prominent role. Stone threw the pitch that our lead prospect analyst Eric Longenhagen has assigned a 60/70 FV (current/projected) on the 20-80 scouting scale a total of 22 times, with a vertical break averaging 30 inches and diving as low 39 inches. Velocity-wise, it ranged from 82.6 mph to 87.7 mph.

Stone was making his fifth major league appearance (and his first since July 4) when he took the mound in Boston. His earlier outings had been on the rocky side — his ERA and FIP are now 10.50 and 6.72 respectively — but there is no denying his potential. The 2020 fifth-round pick out of the University of Central Arkansas is currently no. 40 on The Board with a 50 FV.

Stone told the story behind his signature pitch the day before facing the Red Sox. Read the rest of this entry »

The .300 hitter is dying, Ian Crouch wrote in The New Yorker in 2014. And Bradford Doolittle on ESPN.com in 2019. And Barry Svrluga in the Washington Post just last month. If the .300 hitter is dying, it’s dying the same way you and I are, a little bit each day. Maybe the .300 hitter is just sick.

Why do these stories keep getting written? Well, last week I was checking in on Luis Arraez (come on, dude, I thought you were going to make a serious run at .400!) and came to the startling realization that only nine qualified hitters are on pace to hit .300. Nine! I can’t imagine being a baseball writer, seeing that fact, and not being freaked out enough to write about it.

Baseball is a sport that got its tentacles into the American popular vernacular something like 100 years ago, dropping idioms like eggs. “Three strikes,” “home run,” “lost his fastball,” and dozens of others. “Batting 1.000” is probably a more popular phrase than “batting .300” or “hitting .300,” but the latter is still legible to people who think Christian Walker is what you call pilgrims on the Camino de Santiago.

It’s been a month of upheaval in the AL West. As Jay Jaffe detailed, the Mariners are playing their best baseball of the season right now. A 9-1 stretch has carried them to the top of the division, turning what had been a two-team race all year into a three-way showdown. It’s the most competitive division race remaining, so a lot of people searching for a jolt of excitement down the stretch will be looking west.

Of course, Seattle’s climb to the top of the division didn’t happen in a vacuum. For every action, there’s an equal and opposite reaction, and at the moment, that reaction is happening in Texas. The Astros spent the last week treading water, which allowed the Mariners to roar past them. The Rangers did them one worse; they’ve fallen into a 3-9 tailspin that turned a season-long lead in the division into a deficit.

It’s always tempting to turn a 3-9 stretch – or a 4-8 stretch, or really any stretch that takes a team out of first place – into a referendum on the squad. The Rangers should have seen this coming, the thinking goes. This team? With these weaknesses? It was always going to happen. But let’s withhold judgment for a few minutes and break it down like this: What’s going on in Arlington, and what has to change to turn the team’s fortunes around? Read the rest of this entry »

Félix Bautista has been as emblematic of and as crucial to the Orioles’ sudden breakthrough as any player. In his second major league season, the imposing 28-year-old closer — nicknamed “The Mountain” for his 6-foot-8, 285-pound physique — has emerged as one of the game’s most dominant and valuable relievers, the biggest cog in a bullpen that’s helped to prop up a wobbly rotation. Unfortunately, Bautista’s season is at the very least on hold after he left Friday night’s game with what the Orioles have called “some degree of injury” to his ulnar collateral ligament.

Facing the Rockies at Camden Yards, Bautista entered a 5-4 game in the ninth inning in search of his 34th save and his second in as many nights. He battled Jurickson Profar for six pitches before striking him out on a 101.7-mph fastball, then induced Harold Castro to ground out on a 1-0 pitch. He was one strike away from finishing off Michael Toglia when he stumbled off the mound while uncorking a 102.3-mph fastball that missed up and outside. After he called for time to recover, the sight of him flexing and squeezing his right hand prompted manager Brandon Hyde, head athletic trainer Brian Ebel, and coach José Hernández to check on him and ultimately pull him from the game.

While Danny Coulombe struck out Toglia on his first and only pitch of the night to finish the game, the sequence understandably put a damper on the Orioles’ comeback win. On Saturday, general manager Mike Elias announced that Bautista had injured his UCL and would be placed on the 15-day injured list. It’s unclear yet whether the injury — likely a sprain of the ligament, meaning some kind of tear — is severe enough to require Tommy John surgery. Read the rest of this entry »

After a week hiatus, the FanGraphs Power Rankings are back and there’s been a pretty big shakeup in the top tiers. And as we head into the final month of the season, there are plenty of exciting playoff races still up in the air.

A reminder for how these rankings are calculated: First, we take the three most important components of a team — their offense (wRC+), their pitching (a 50/50 blend of FIP- and RA9-, weighted by starter and reliever IP share), and their defense (RAA) — and combine them to create an overall team quality metric. I also add in a factor for “luck,” adjusting a team’s win percentage based on expected win-loss record. The result is a power ranking, which is then presented in tiers below.

After the recent collapse of the Rangers, the Braves now stand alone atop these rankings. They’re on cruise control right now, with the NL East locked up and a first round bye into the divisional round all but guaranteed. They’ve won 13 of their last 16 games, with six shutouts and just 2.9 runs allowed per game during this stretch. They’ve got a huge four-game series in Los Angeles against the Dodgers this weekend that could go a long way towards determining the top seed in the NL.

No team in baseball is hotter right now than the Mariners. As recently as mid-July, they were 10 games behind Texas, but they’ve lost just five games in August and have surpassed both the Rangers and the Astros to take the division lead in the AL West. It’s the first time the M’s have led their division this late in the season since 2003. The offense that had been so frustratingly inconsistent earlier in the season has exploded this month; they’re scoring more than six runs per game and lead all of baseball with a 147 wRC+ in August.

A 4-2 record last week marked the low point of the Dodgers’ August; those two losses were just the third and fourth of the month for Los Angeles. They’re being led by two guys who are suddenly challenging Ronald Acuña Jr. in the NL MVP race: Freddie Freeman and Mookie Betts. The former is in the midst of the best full season of his career at the plate, in the field, and on the basepaths. Betts, meanwhile, enjoyed an emotional return to Boston this weekend and extended his hitting streak to 15 games.

After starting the month with an eight-game win streak and 12 wins in their first 14 games in August, the Rangers have been in free fall since then. A win on Saturday snapped an eight-game losing streak, but they lost an ugly, 13-inning walk-off affair in Minnesota on Sunday. That dropped them to second place in the AL West, the first time they’ve been out of the top spot since April 8. Their bullpen in particular has been a sore spot during this stretch; Texas relievers have allowed 35 runs over their last 10 games, with six blown saves.

The Orioles were dealt a serious blow when their ace closer Félix Bautista was sidelined with elbow discomfort last week. Losing a pitcher of Bautista’s caliber would be a problem for any club, but for Baltimore, it’s a tremendous loss. So much of the O’s success this season has hinged on the success of their bullpen. Their shot at the playoffs probably isn’t threatened, but their grip on the AL East division lead is suddenly a little more tenuous.

With the Mariners budging in, the fight for the AL West crown is suddenly very crowded. The Astros have played second fiddle to the Rangers all season long, but now they have a third team to contend with. The ‘Stros offense has been frustratingly inconsistent this month; they’ve had just as many games where they score nine or more runs as they’ve had games where they score two or fewer. Kyle Tucker has been a rock in the middle of their lineup, and Jose Altuve has been fantastic since returning from his thumb injury, but Yordan Alvarez has been kept in check by various maladies, and both José Abreu and Jeremy Peña have been great disappointments this year.

The Brewers won their eighth straight game on Sunday and have now extended their lead in the NL Central to four games. They have a huge series against the Cubs on the docket this week, which could go a long way towards determining how close this division race is going to be down the stretch. Milwaukee’s offense has come alive lately, scoring more than seven runs per game after notching just three total runs during the three-game sweep at the hands of the Dodgers that immediately preceded this win streak. That’s a very good sign, as run scoring has been such an issue for them during this recent competitive window.

Thanks to a floundering offense and an extremely thin pitching staff, the Giants have fallen out of Wild Card position, sitting even with Cincinnati at a game and a half back of the Diamondbacks. The depth of their roster has been strained to the breaking point by a cavalcade of injuries. They have key series against the Reds and Cubs coming up over the next two weeks, and they desperately need some positive results in those matchups to stay in the playoff picture.

Meanwhile, the roller coaster the Diamondbacks are riding is currently back on the upswing. They started the month with a nine-game losing streak, but they’ve gone 12-3 over their last 15 games to get right back into the thick of the NL Wild Card race. They just won a huge four-game series against the Reds over the weekend, one that featured one of the most dynamic single plays you’ll ever see.

The teams in this tier are tangibly better than those in the tier below, but they’ve either fallen out of the playoff picture or are such long shots that they fit better as a potential spoiler than a true contender. The Padres exemplify this contrast; they’re underlying team quality is solid but they’re just too far back in the NL Wild Card race to truly make a run at it. Of course, being a good team that isn’t really good enough has plenty of rough implications for their future. The talent on their roster looked dominant on paper, but the actual results on the field have been disappointing to say the least. After getting swept by the Brewers over the weekend, you can probably put a pin in San Diego’s slim postseason hopes.

Speaking of teams at a crossroads, a 2-12 record over the last few weeks has sunk whatever last hopes the Yankees had of making a postseason run this year. If things keep going this way, they’ll finish in last place in the AL East for the first time since 1990; it would be their first losing season since 1992. To make matters worse, their future outlook seems pretty bleak unless they’re able to miraculously fill their aging roster with young talent. For the first time in nearly three decades, the Yanks are facing the decision to rebuild, or at least reset, their roster.

As if things weren’t bad enough for the Angels, Shohei Ohtani injured his UCL last week and is done pitching for the season (and perhaps next season, too, depending on the severity of the tear). That same day, they placed Mike Trout back on the IL after he played in just a single game thanks to renewed discomfort in his left hand. Los Angeles was already well out of the playoff picture thanks to a ghastly 7-17 record in August, but depriving baseball of two of its greatest talents is a tragedy.

In the midst of another lost season, the Tigers finally have something to give them a shred of hope: the breakouts of Spencer Torkelson and Kerry Carpenter. After a really rough introduction to the big leagues, the former first overall pick is finally close to living up to the hype surrounding his draft selection and ascent through the minor leagues. Meanwhile, Carpenter’s emergence has largely flown under the radar, but he’s been Detroit’s best hitter since getting called up last August. The Tigers have plenty of work left to do before breaking out of this rebuild cycle, but those two hitters give them another pair of building blocks to work with.

Things finally came to a head for White Sox executive vice president Kenny Williams and general manager Rick Hahn last week. The architects of the team for nearly two decades, both were fired from their roles, as Chicago has squandered a bunch of young talent over the past few years. The White Sox will head into next year in search of a new direction, though with Jerry Reinsdorf still in place as the team’s owner, it remains to be seen how different of a course they can chart.

Throughout the 2019 postseason, the Washington Nationals made a habit of using their entire margin of error. They needed a three-run, last-ditch rally to get out of the Wild Card game, then another 11th-hour comeback to get past the Dodgers in Game 5 of the NLDS. Dave Martinez tried to shorten his pitching staff as much as possible, a desperation move that’s backfired on manager after manager as long as there have been playoffs.

By the time Game 6 of the World Series rolled around, the Nationals were facing elimination once again. They’d lost three straight to the 107-win Astros and needed to beat Justin Verlander on the road to stay alive. Patrick Corbin had been run ragged. Max Scherzer’s body had locked up to the point where he couldn’t dress himself. Martinez had already gambled with the likes of Tanner Rainey and Wander Suero more than anyone was comfortable with.

Then Stephen Strasburg stepped up and did something you don’t see pitchers do much anymore. He handled it.

After a rocky first inning, Strasburg kept the irrepressible Astros offense off the board into the ninth. The Nats once again scored bunches of runs late, and the next evening they were hoisting the proverbial piece of metal. Read the rest of this entry »
