If you were only going by raw stat lines, the end of April would have been an understandable time to give up on Jo Adell. After struggling mightily in parts of four seasons with the Angels as well as the first half of 2024, he showed some positive gains in the second half before being shut down due to an oblique strain in early September. He finished in replacement-level territory, with a 90 wRC+ and 0.1 WAR, then was dreadful at the start of this season, sticking out even among one of the majors’ worst offenses. Lately, though, Adell has come around in promising fashion, offering hope that he can be a productive big leaguer after all, if not the star so many once believed he could be.

Originally, I intended to use the 26-year-old Adell to lead off the 2025 version of an article I wrote last year, covering players who had improved the most after dismal starts — even if their overall numbers were camouflaged by their early struggles and still came off as rather ordinary. Using May 1 as a cutoff, with a minimum of 80 plate appearances on either side, I found that Adell had improved the most from the first leg of the season to the second. Here’s the table, with the stats updated through Sunday:

Adell hit just .190/.236/.310 with two home runs in March and April while striking out 27% of the time, but from the start of May through Sunday, he hit .255/.344/.582 with 11 homers while trimming that strikeout rate to 23.2%. He was about half a win below replacement level before May 1, and has been about a full win above since.

I’ll dig into the numbers below, but first, a recap. A 2017 first-round pick out of a Louisville high school, Adell cracked our Top 100 Prospects list in each of the next three seasons, ranking as high as no. 4 in 2020, as a 65-FV prospect, and he was similarly regarded by other outlets thanks to his combination of plus-plus raw power and plus speed. But since debuting early in the 2020 season, he has generally struggled to make good contact, or any contact at all for that matter, with his lack of refinement limiting his opportunity to show off the tools that so tantalized talent evaluators. In a total of 178 major league games from 2020–23, he hit just .214/.259/.366 with 18 homers in 619 plate appearances en route to a grim 70 wRC+. After appearing in 88 games with the Angels but managing just a 77 wRC+ and -0.2 WAR in 2022, he played only 17 games in the majors in ’23 while returning to Triple-A Salt Lake for the fourth year out of five. As I joked early last year, when it looked like he might be breaking out — which proved not to be the case, alas — if he’d spent just a bit more time in my hometown, my parents would have been obligated to invite him over for dinner.

Jay Jaffe: Howdy, folks! Welcome to another edition of my weekly chat! It’s a grey day in Brooklyn as we’re amid a week of rainy weather, and I’ve got the occasional sounds of workers demolishing our rotting backyard deck right outside my window (https://bsky.app/profile/jayjaffe.bsky.social/post/3lrst55laqs2y).

12:02

Jay Jaffe: Yesterday I wrote about Cole Ragans’ rotator cuff strain and the state of the Royals’ rotation https://blogs.fangraphs.com/the-royals-have-lost-cole-ragans-for-awhil…

Jay Jaffe: Today I’ve got a piece on Jo Adell that should be published sometime during this chat. He had a dreadful March/April but has been very good since the start of May, and especially good in June.

12:06

Jay Jaffe: Good question. This deal is a noteworthy exception to my recent declaration about how few substantial trades happen in May or June, with everybody looking to the deadline. I’ve seen conflicting reports about the extent to which the Red Sox tried to trade Devers — how many teams they spoke to besides the Giants. Given the underwhelming return, it sure doesn’t feel as though they dealt him to the highest bidder, and they’d have gotten more for him at a higher-leverage period in late July. Then again, this trade appears to be primarily about dumping his salary and sending a my-way-or-the-highway message to the impressionable youths in the Red Sox clubhouse.

12:07

Jay Jaffe: I don’t think there would have been much harm for the Sox in waiting at least until the end of June, but if they had continued winning, they might have talked themselves out of it. This way they get to look like hardasses, which as we know is the most important part of being a baseball executive.

Alright, Dodgers bullpen! This is what we’ve been training for. They hit our guy. This is not a drill. I know it was an accident. I know it would have been the world’s worst time to throw at a hitter, down by a run in the fourth inning, a runner already on base, ahead in the count with the platoon advantage, unprovoked. But none of that matters right now. It’s time to look tough.

Everybody crowd up against the fence like you can’t wait to burst through the door. Time to posture. Strike a pose. This moment right here? This is the reason we watched The Warriors so many times. It’s time to get mean. It’s time to maybe, possibly, not really but you never know just in case, shove somebody a bit. We’re ready to jog out there. We’re ready to flex. Everybody ready for a fight?

Below are two changeups. Can you tell which one is better?

First up is Griffin Jax’s power changeup. He throws it over 92 mph; at two inches of induced vertical break (IVB) and 15 inches of arm-side run, it almost resembles a filthy left-handed slider:

Second is Hunter Gaddis straight change, floating up to the plate with 10 inches of IVB at an average velocity of 78 mph:

So, which one would you take? That’s a bit of a trick question: By whiff rate, these two pitches are virtually identical. Jax’s changeup ranks second in all of baseball with a 57.3% whiff rate; Gaddis’ is right behind him in third. Stylistically, they’re opposites; by the results, they are indistinguishable.

If you were creating the perfect fastball or the perfect slider in a video game, it’d be a straightforward process. Crank up the velocity, max out the vertical break, and those pitches will generally improve in a roughly linear fashion. Not so with changeups. Pitch models struggle to accurately grade these pitches because their quality can’t as easily be captured by velocity and movement in a vacuum. The Cole Ragans changeup, for example, gets a roughly average grade by Stuff+ despite performing like the best changeup in the sport over the last handful of seasons. It’s slow, and it barely moves — what makes it so good?

Thanks to new data from Baseball Savant, I think the answer might soon be clear. Read the rest of this entry »

Ben Lindbergh and Meg Rowley discuss the Rafael Devers trade in depth, covering why Boston made the move, the resulting fan frustration, and the Giants impact. Then (57:56) they cover bad news about Christian Montes De Oca, John Brebbia, and Johnny O’Brien before bantering about Shohei Ohtani’s return to the mound, the Rays rotation, Charlie Morton’s turnaround, Patrick Corbin, why the Astros are still good, Aaron Boone, and tennis-style boundary reviews.

When I volunteered to write about the Aaron Civale-for-Andrew Vaughn swap, I thought I was going to be covering the most interesting trade of the month. At the very least, I thought I’d be putting out the most interesting trade write-up of the day. It’s not that Civale and Vaughn are huge household names, but you don’t often see notable major leaguers traded for one another in June. Trade season isn’t supposed to have started yet! I looked back through the FanGraphs archives to find pieces with the “trade” tag that dealt with June transactions. I found six others:

1. The Phillies acquired Jay Bruce from the Mariners for Jake Scheiner (2019).

2. The Yankees acquired Edwin Encarnación from the Mariners for Juan Then (2019).

3. The Blue Jays acquired Adam Cimber and Corey Dickerson from the Marlins for Joe Panik and Andrew McInvale (2021).

4. The Mariners acquired Carlos Santana for Wyatt Mills and William Fleming (2022).

5. The Rangers acquired Aroldis Chapman for Cole Ragans and Roni Cabrera (2023).

6. The Giants acquired Rafael Devers for Kyle Harrison and Jordan Hicks (2025).

Then, of course, there’s one you’re reading right now. Of those seven June trades we’ve covered, four took place before the last week of the month: the two from 2019 and the two from the past 72 hours.

Do I feel slighted that mine is no longer the biggest trade story of the month, the week, or even the day? That through no fault of my own and no fault of my editors’, my story has been relegated to a secondary position? No, not really. But if I did, I’d be able to relate quite well to Civale. Last week, the Brewers informed the right-hander he’d be moving to the bullpen. Civale was understandably upset. He’s in his free agent walk year, and moving to a long relief role could diminish his earning potential in the offseason. What’s more, aside from one postseason appearance last fall, he has never worked out of the bullpen in his professional career. Above all else, he remains a perfectly capable back-end starting pitcher. He didn’t cost himself a rotation spot with his poor performance; the Brewers simply had five superior options.

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.

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. Read the rest of this entry »

The Royals’ rotation was a key reason last year’s team made the playoffs for the first time since 2015, with the one-two punch of Seth Lugo and Cole Ragans leading the way. It was the first full season in the majors for Ragans, whose five-pitch mix helped him dominate hitters en route to an AL All-Star selection and a fourth-place finish in the Cy Young voting. Unfortunately, his follow-up season hasn’t gone so smoothly, and after landing on the injured list with a groin strain in May, Ragans has now been diagnosed with a rotator cuff strain and figures to miss significant time.

A 2016 first-round pick who underwent two Tommy John surgeries before debuting for the Rangers in ’22, Ragans enjoyed a meteoric rise in ’23, after his average fastball velocity jumped from 92.1 mph to 96.5. Not until he was traded to the Royals in a June 30, 2023 deal centered around Aroldis Chapman did he finally stick in a rotation (he had a nine-start trial in 2022), but once he did, the results were revelatory. He posted a 2.64 ERA, 2.49 FIP, and a 31.1% strikeout rate in 12 starts totaling 71.2 innings post-trade; his 2.4 WAR ranked 12th in the majors from July 1 onward. On the strength of an impressive fastball-changeup combo accompanied by a knuckle curve, slider, and cutter, he solidified his spot among the majors’ top pitchers last year. He made 32 starts and finished second in the AL in FIP (2.99), strikeouts (223), strikeout rate (29.3%), and WAR (4.9); seventh in innings (186.1 innings); and eighth in ERA (3.14).
