After missing out on the postseason last year, breaking a four-year streak, the Brewers are back in the playoffs this year. They’ve been the model of consistency over this past half decade; they are the only other team apart from the Astros and Dodgers to have won at least 86 games in each of the last six full seasons. But for all that regular season success, they’ve only won one postseason series during this stretch, a Division Series back in 2018. They have one of the strongest run prevention units in baseball and are hoping that will carry them deep into October.

Milwaukee’s first-round opponent, the Diamondbacks, will be making their first playoff appearance since 2017. They’re breaking out of a long rebuilding cycle a little ahead of schedule thanks to the phenomenal rookie campaign of Corbin Carroll. On paper, they’re significant underdogs when compared to the dominant arms the Brewers can bring to bear, but they’ve got enough young talent to make some noise as a surprise contender:

The playoffs start on Tuesday, and we are going to cover every single game, from the Wild Card round to the World Series. But those games are played by humans, and those humans have to find a way to avoid murdering each other over the course of a very long season. Inventing goofy celebrations is a good way to inject some fun into the proceedings. This article and its American League counterpart, which will run tomorrow, will break down how each playoff team celebrates when a player reaches base or the team notches a victory. (I’m going to skip the home run celebrations because they’ve already been covered very thoroughly, and because they’re sure to get plenty of camera time as October unfolds.) The point of this article is to help you enjoy the smaller celebrations that might otherwise go unnoticed.

One important note: This is necessarily an incomplete list. I spent a lot of time looking, but I wasn’t able to track down the origin of every single celebration. When you search for information about a team’s celebration, you have to wade through an ocean of articles about the night they clinched a playoff berth. The declining functionality of Twitter (now known as X) also made it harder to find relevant information by searching for old tweets (now known as florps). When I couldn’t find the truth about a celebration’s backstory, I either gave it my best guess or invented the most entertaining backstory I could think of. If you happen to know the real story behind a particular celebration, or if you’d like to share your own absurd conjectures, please post them in the comments. Read the rest of this entry »

The rookies took the spotlight this past Saturday in Baltimore, as the Orioles battled the Rays and clinched their first playoff berth since 2016 via an 8-0 victory. Leading the way on the offensive side was 22-year-old Gunnar Henderson, who led off the first inning with a first-pitch single off Tyler Glasnow and came around to score the game’s first run, then added a two-run homer in the second and an RBI single in the fourth, helping to stake rookie starter Grayson Rodriguez to a 5-0 lead. The 23-year-old righty turned in the best start of his brief big league career, spinning eight shutout innings while striking out seven and allowing just five baserunners. A day later, when the Orioles beat the Rays in 11 innings to reclaim the AL East lead, a trio of rookies — Shintaro Fujinami, Yennier Cano, and DL Hall — combined to allow just one hit and one unearned run over the final three frames.

Earlier this month, colleague Chris Gilligan highlighted the contributions of this year’s rookie class. With just under four weeks to go in the regular season at that point, rookie pitchers and position players had combined to produce more WAR than all but three other classes since the turn of the millennium. Collectively they’re now second only to the Class of 2015 (more on which below), and since the publication of that piece, four teams besides the Orioles, all heavy with rookie contributions, have made headway in the playoff races. The Dodgers clinched the NL West for the 10th time in 11 years on Saturday, while the Mariners and Diamondbacks are clinging to Wild Card spots, and the Reds are in the thick of the NL race as well.

In the Beforetimes, mid-September brought my annual check-in on the potential for end-of-season chaos in the playoff races via the Team Entropy series. With last year’s introduction of an expanded and restructured postseason, however, Major League Baseball did away with the potential for scheduling mayhem in favor of a larger inventory of playoff games. Along with the expansion of the playoff field from 10 teams to 12 and of the Wild Card round from a pair of winner-take-all games to a quartet of three-game series, MLB also eliminated all winner-take-all regular-season tiebreaker games. In the name of efficiency, we have no more Games 163 and no more potential Bucky Dents. Instead, ties, even for spots where the winner would receive a postseason berth and the loser would go home, are decided by mathematics. It’s enough to make a fan want to shout, “Hey, Manfred, pull your head out of a spreadsheet and watch an elimination game!”

The untangling of the often-chaotic scenarios by which those one-game tiebreakers could come about was Team Entropy’s raison d’etre. But particularly with so many close races, there’s still enough untangling to do in potentially complex tie scenarios that I’ve chosen to continue a version of this exercise, pouring out a cold one for what might have been. If what we’re left with isn’t exactly chaotic, you can thumb your nose at the commissioner as you take a seat on the Team Un-Tropy bandwagon. Read the rest of this entry »

Zac Gallen couldn’t even wait until the sun went down to thumb his nose at my attempt to sort out the NL Cy Young race — or at least at the notion that he was out of it. While I mentioned Gallen in passing in a piece focused on Spencer Strider and a few other pitchers who appeared to have the best statistical cases for the award, I had little to say about Gallen, who spent much of this season as the league’s frontrunner but has faded in the second half, and was coming off back-to-back bad starts that had further puffed up his numbers. On Friday afternoon, the 28-year-old righty threw a three-hit complete-game shutout against the Cubs in a 1-0 win, prompting me to take a second look at situating him within the race as the candidates head into the home stretch.

Building off a 2022 campaign in which he posted a 2.54 ERA, 3.05 FIP, and 4.2 WAR en route to a fifth-place finish in the Cy Young voting, Gallen jumped out to the front of the race early this season. He ran off a streak of 28 consecutive scoreless innings from April 4–26, with an eye-opening 41-to-1 strikeout-to-walk ratio along the way. He finished June with a 2.72 ERA and 2.06 FIP, led the NL in FIP (2.85) and fWAR (3.8) at the All-Star break, and earned the starting nod for the All-Star Game opposite Gerrit Cole. He’s been the consensus pick for the Cy Young in four monthly polls of MLB.com voters.

With Instructional League underway in Arizona (casts look of disappointment toward Florida) and Fall League rosters likely about two weeks out, the time has come to line the coffers with data and re-worked scouting reports in preparation for another round of farm system audits. Especially at the up-the-middle positions, defense is both very important and also a bit of a black box for readers, as there aren’t many publicly available minor league defensive stats and so much of evaluating defense is visual. I’ve recently been working on a video deep dive on the position players currently graded as 50 FV prospects or better, specifically to evaluate their defense in detail. Here I’ve taken a pass at the shortstops, providing video supplements for the prospects who I’ve evaluated in the 55 FV tier and above. I’ve made changes to their defense and arm tool grades over on The Board as a result of this exercise, and highlight the instances where this has caused a change to the player’s overall FV grade in the analysis below.

I’ve cut the videos in such a way that you can see each shortstop making similar plays one right after another. The videos feature plays to their left where I want to see them flip their hips and throw, plays that show the extreme end of their range, backhand plays in the hole to their right, plays coming in on the grass, and double play attempts. The fewest balls in play I watched for an individual player was 36 (Colson Montgomery and Dyan Jorge) and the most was closer to 70 (Jackson Holliday, Carson Williams and Marcelo Mayer).

On Monday, the Rangers and Diamondbacks played a classic at Chase Field. It started as a pitcher’s duel between Jordan Montgomery, who pitched beautifully over eight scoreless frames, and a cadre of Diamondbacks pitchers led by bulk man Slade Cecconi, who allowed the only run of the first eight innings on a solo shot off the bat of Adolis García. Then, things got chaotic. From the ninth inning on, the game swung from an 88.4% chance of a Texas win to an 81.3% likelihood for Arizona, then back to 95.1% odds in favor of the Rangers before a final swing back to the D-backs on a Tommy Pham walk-off double. Not to be confused for the heart rates of each team’s fans Monday evening, the win probability chart came out looking like this:

Last week, Ben Clemens wrote about how neat Win Probability Added is, and its merits as a part of the MVP discussion. While Ben’s piece made the great point that WPA is not “just a storytelling statistic,” lobbying for its use in measuring value over a season, its storytelling powers are indeed pretty remarkable. So much of the drama within Monday’s game was made quantifiable by measuring the shifts in win probability. Ketel Marte’s game-tying homer in the ninth was worth .467 WPA, or 46.7 percentage points of win probability; Nathaniel Lowe’s go-ahead double was worth .454; Tommy Pham’s walk-off was worth .754, the 11th-highest WPA value for any single play this year. That’s three hits that turned the game on its head, and then back on its feet, and then back on its head again. Read the rest of this entry »

In an attempt to arrest a slide that began in early July, the Diamondbacks were busy in the run-up to the August 1 trade deadline, but so far, their moves haven’t been enough to turn things around. In fact, they have yet to win a game in August, having finished a seven-game road trip by losing six in a row to the Giants and Twins. On Sunday, their highest-profile deadline addition, former Mariners closer Paul Sewald, failed to retire a batter in his first save opportunity since the trade. Instead, he served up a game-tying homer to Max Kepler on his first pitch and then, after a walk, a two-run walk-off homer to Matt Wallner. Ouch.

After spending the majority of the first half leading the NL West, the Diamondbacks have slipped to sixth in the NL Wild Card race, 1.5 games behind the Cubs and Reds, who are tied for the third spot. Their trend is actually worse than that. Since winning on July 1 to lift their record to 50-34 and restore their NL West lead to three games, the Snakes have gone 7-22 (.241). That’s worse than the A’s (9-19, .321) or any other team in the majors. It’s not as though they’ve been particularly jobbed in the process; their Pythagenpat record is the majors’ worst in that span as well:

To be fair, the Diamondbacks weren’t expected to be a powerhouse this year; after going 74-88 last year, they projected for 78.4 wins via our preseason Playoff Odds. In a slow-starting NL West, they took over a share of first place for the first time on April 8, when they were 5-4, and finished the month 16-13, which was good enough to tie for first. Despite going 17-10 in May, they didn’t get a share of first place again until June 1, but they spent that entire month atop the division — most of it with sole possession of first place — while going 16-11.

It was around that time that Corbin Carroll’s season started taking an unfortunate turn. On June 29 — the same day he was named as a starter for the National League in the upcoming All-Star Game — the 22-year-old outfielder left a 6-1 loss to the Rays after four innings, having experienced soreness in his right shoulder during a third-inning plate appearance. It was the same shoulder on which he’d undergone surgery to repair a torn labrum in 2021, which cost him nearly the entire season. In the wake of his removal from the game, he underwent strength testing, which showed that his shoulder was strong and stable, but the Diamondbacks gave him a breather, limiting him to a single pitch-hitting appearance over the next three days. After returning to the lineup, he played just three more games before leaving the team’s July 6 tilt against the Mets in the seventh inning, once again in pain. “I took a swing, and I felt a shift in my shoulder, shocking, tingling sensation go down my arm and then my hand go numb,” he told reporters. “I was just holding it thinking it came out of the socket, pretty much thought that the season was over.”

Despite his initial concerns, Carroll had not experienced a dislocation, and his MRI came back clean. He was back in the lineup the next day, and while he’s certainly had his moments since then — and hasn’t missed a game — his production and quality of contact are down considerably since the first incident:

Note that with two hits and two walks on Sunday, Carroll raised his post-July 1 wRC+ nine points; he was at 96 previously. Along the way, his swinging strike rate has spiked from 8.4% to 12.4%, and his chase rate from 28.8% to 32.6%, though his strikeout rate has barely budged, from 19.8% to 20.1%.

Maybe Carroll’s downturn in production is related to his shoulder woes, maybe it’s just the league adjusting to a player who looked like an MVP candidate early in the season, or maybe it’s just regression, more on which below. One way or another, it’s been poorly timed, in part because he’s not the only Diamondback who has tailed off in recent weeks:

Just four Diamondbacks have a 100 wRC+ or better since the start of July, one of them a catcher (Moreno) who has been limited to 11 of the team’s first 29 games in that span and is now sidelined by left shoulder inflammation. Moreno, Thomas, and McCarthy are the only three players with a higher wRC+ since the start of July than before, and they’re still below average offensively overall. Deadline additions Tommy Pham (from the Mets) and Jace Peterson (from the A’s) have yet to make an impact, going a combined 4-for-30, all singles.

Meanwhile, note that not only has Carroll fallen off steeply but so have Gurriel and Perdomo, both of whom joined him on the NL All-Star squad but might as well be on the side of a milk carton these days. Setting the narrative of Carroll’s shoulder injury to the side for a moment, this is striking:

All three players hit well above their Statcast expected stats through the end of June, particularly Perdomo, a slappy switch-hitter who doesn’t hit the ball hard at all; his season barrel rate is 1.2%, his hard-hit rate 19.9%. Then it’s as though the Regression Monster showed up and took a bite — each of these three players has seen about a 75-point swing in their wOBA-xwOBA differential.

Overall, the Diamondbacks hit .263/.330/.437 through the end of June, ranking fifth in the majors in scoring (5.11 runs per game) and seventh in wRC+ (106). Since then, they’ve hit just .227/.302/.373 while ranking 29th in scoring (3.44 runs per game) and 26th in wRC+ (83). Their performance against every major pitch type except changeups has fallen off by at least 50 points of SLG and 25 points of wOBA:

Yikes. They were punishing four-seam fastballs earlier in the season, but that’s stopped, and they’ve particularly gotten eaten alive by sliders and sweepers lately. What’s especially strange is the general downward trend of their more recent numbers despite the weather getting even warmer, which tends to increase offense. Of course, it’s as hot as the surface of Mercury in Arizona, so maybe the Diamondbacks have just wilted in the heat.

That does seem to be true with the team’s pitching, particularly the bullpen:

Good gravy. In writing about the Sewald trade — which sent Rojas and prospects Dominic Canzone and Ryan Bliss to Seattle — I noted that manager Torey Lovullo had been working with a matchup-based closer-by-committee system involving righties Miguel Castro, Kevin Ginkel and Scott McGough and lefty Andrew Chafin. However, I did not drill down to see just how bad things had gotten for them in the recent past. Using the July 1 cutoff again, with full awareness of the small samples in play, Ginkel has pitched well (0.75 ERA, 2.35 FIP in 12 innings), but the other three had been torched, with Castro (6.00 ERA and 6.60 FIP in 12 IP) the “best” of them, though he had stopped getting ninth-inning save chances, and Chafin (9.95 ERA and 5.63 FIP in 6.1 IP) and McGough (8.76 ERA and 6.91 FIP in 12.1 IP) utterly terrible. Chafin had two blown ninth-inning saves that led to losses in that span; he’s now a Brewer.

As for the rotation, it’s been pretty unstable, with Zac Gallen and rookie Ryne Nelson the only real constants, and both of them experiencing fall-offs since the start of July. Gallen pitched to a 3.02 ERA and 2.73 FIP in 104.1 innings through June, making his first All-Star team, but has yielded a 4.17 ERA and 4.12 FIP in 45.1 innings since, with his home run rate increasing from 0.6 per nine to 1.6. Nelson went from a 4.97 ERA and 4.44 FIP to a 5.59 ERA and 6.19 FIP, not that it should have been too surprising given his double-digit barrel rate even in the “good” times. Merrill Kelly, the team’s second-best starter, missed four weeks (most of July) due to a blood clot in his right calf but has been solid when available. Tommy Henry showed some improvement before being sidelined last week due to elbow inflammation. Brandon Pfaadt has been getting better results since being recalled on July 22 than prior, though his overall ERA of 7.11 in 44.1 innings is pretty damning. Also sporting an unsightly ERA (7.38) is Zach Davies, who has been dreadful on both sides of the divide while missing time with oblique and back injuries. Slade Cecconi, the team’s 2020 first-round pick, just made his major league debut on August 2 in place of Henry and acquitted himself reasonably well in a losing cause against the Giants, though his catcher (Herrera) had a rough time on the rookie’s first strikeout.

Given their current injury situation, the Diamondbacks now find themselves trying to stay afloat with just two starters who have demonstrated the ability to be league average or better, plus three rookies who have combined for a 5.63 ERA and 5.31 FIP. It’s not like the cavalry is on the horizon, either. The team’s playoff odds, which stood at 76.4% through the end of June (24.9% division, 51.5% Wild Card), are down to 21% at this writing, including just a 0.7% chance of overcoming their 8.5-game deficit to win the division. Considering that they lost 110 games just two seasons ago, they’ve certainly made progress to get to this point, but it seems quite apparent given their performance over the past five-plus weeks that they’re not quite ready for prime time.

Slade Cecconi must have been nervous. Staring down the first batter of his big league career, the 24-year-old couldn’t quite get on top of a 2-2 curveball. The looping pitch floated harmlessly past LaMonte Wade Jr., well above the strike zone for ball three. Wade called time out, and Cecconi used the respite to take a few calming breaths before returning to the rubber.

For the sixth pitch in a row, catcher Jose Herrera set up on the outside corner. For the sixth pitch in a row, Cecconi overthrew it, yanking a four-seamer toward the left-hand batter’s box. Wade had no time to react as it screamed in toward his hands at 94.8 mph. Only after the ball had made contact did he recoil, leaning away so far and so fast that he had to start jogging backward toward first base just to keep from falling over. Then things started to get stuck. Read the rest of this entry »

There’s something strange going on in the desert. The Diamondbacks have been one of the best stories in baseball this year, led by Corbin Carroll and a motley crew of veterans and rookies. An early season tear sat them atop the NL West, and we gave them an 80% chance of making the playoffs on July 1. Whoops – they’ve gone 8-16 since then, the worst record in the NL, and now they’re scrambling to make the playoffs. Time to make some trades!

Tommy Pham fits perfectly with what Arizona is going for. After a desultory three-year stretch from 2020-22 where he posted a 94 wRC+, he’s been one of the lone bright spots for the Mets this year. He’s hitting .268/.348/.472, and his quality of contact has been even better than that; he has a shiny .390 xwOBA and is smashing balls left and right. His plate discipline, always a strength, has never been better. He’s posted as much WAR this year as in those three previous ones.

The Diamondbacks could use that kind of production. They’ve relied on four regular outfielders this season, and only Carroll has been good. Jake McCarthy has an 85 wRC+ and the underlying stats to match. Alek Thomas checks in at a 79 wRC+. Lourdes Gurriel Jr. is the best of the group, but that’s faint praise; he’s hitting .249/.296/.448 with a 98 wRC+ himself. Murderer’s row, this is not. Read the rest of this entry »
