The Joe Sheehan Newsletter: ABSolute Beginnings
Vol. 18, No. 13
April 2, 2025

The only thing anyone wants to talk about is the new system for challenging ball and strike calls. Sandy Alcantara throws a shutout, the Brewers start 5-1, the baseballs are still dead...no, it’s all taking a back seat to the implementation of an automated system for getting called pitches correct. If you remember the Torpedo Bat Era (March 29, 2025 - April 3, 2025), you’ll recognize the same energy today.

As someone who would just as soon see all pitch calls made by the automated system (ABS), I consider the new rules a half-measure. They put the onus on the players to officiate the game, they gamify a part of baseball that should be straightforward, and they still do not get enough of the calls right. Players, especially hitters, have seemed reluctant to trust their judgment given the cost of losing a challenge, so many pitches thrown outside the zone remain strikes. MLB has enormous quantities of information on who is challenging and how often calls are being reversed, but it’s the pitches outside that data set, the ones that go unchallenged by choice or by rule, that are more interesting to me.

Thanks to all that data collection, we’re hearing a lot of conversation about which teams and players have been most successful at challenges. I gave up being the small-sample police a long time ago, so go crazy with it. Me, I am not sure at all that challenging will actually be revealed as a skill. I am sure that if it is, we won’t be able to suss it out before Easter Sunday. If you want to jump to conclusions, you can, just keep in mind that as I write this, the Marlins are in first place, Joey Wiemer leads the league in hitting, Liam Hicks leads in RBI, and Paul Skenes has an ERA of 9.53.

I have two genuine takeaways from the first week of challenges:

They’re fast, but still too slow, by choice. The actual time it takes to discern and communicate the correct call to the home-plate umpire should be maybe five seconds. The umpire shouldn’t have to move to get the word that the call stands or is changed. Instead, we get this elaborate production; the umpire turns to the crowd and the press box and announces “The batter is challenging the pitch.” Then he steps to the side to watch the largest video board in the park run a T-Mobile ad wrapped around a visualization of the pitch, mound to plate, followed by a verdict and, and if the call was wrong, a display of the distance by which it was wrong.

The only important words in that graf are “T-Mobile ad.”

A process that should take five seconds and be mostly invisible takes 15 with dance moves because MLB is making a buck off it. I’ve talked about this in the context of commercial time; MLB has jumped through all kinds of hoops to shorten games, but when it comes time for the playoffs, they sell extra commercials because they value their cash more than your time.

Should I care about the extra ten seconds? It’s not just the time, it’s the elaborate process n the service of an ad that bugs me. We’ve had at-bats with multiple challenges, we’ve had half-innings with three, four, five challenges, and maybe it is just me, but I am already sick of that visualization and all that bright pink. 

It doesn’t have to be this way and it shouldn’t be this way. Just buzz the ump with the correct call and move on. You won’t miss the T-Mobile money, there’s probably another gambling deal just around the corner.

We’re too focused on the close calls. Many of the visualizations have shown pitches to be just barely inside or just barely outside the zone, and changed accordingly. This has caused some consternation about whether the umpire’s call should be reversed in these instances. I think this is a silly conversation that mistakenly centers the umpire and his call as opposed to the what the players did. I care where the ball was relative to the strike zone, not where the umpire thought it was relative to the strike zone.

As I have said any number of times, umpires are mostly guessing on the edges, using the count, the game state, the catcher’s movement, and other cues to push them to one call or the other. This isn’t an indictment of them as people or professionals -- the job of calling pitches is simply too difficult for humans to do given modern pitching.

The focus on the close ones, though, has served to block out the single best thing about ABS: The near-elimination of utterly ridiculous strike calls. I accept that umps are largely flipping coins on pitches just inside or outside of the zone. What I never accepted were the strike calls on pitches that never came near the plate, the ones called strikes because the pitcher “hit the target” or “had earned that pitch,” or “because I want to do my little punchy dance.” Those were the ones distorting the pitcher/batter relationship, slowing down the game as the pitcher chased those strikes, and raising the overall strikeout rate.

A process that started last year with the umps being graded differently continues now with ABS, which gives batters recourse on those pitches that were simply never supposed to be called strikes. I have to be honest, what I’ve mostly noticed is fewer of those pitches even being called strikes to begin with, and with that, fewer attempts by pitchers and catchers to exploit the old hole in the system.

In a soft-focus feature on the beleaguered umpires, Sam Blum quotes Jim Joyce:

Jim Joyce, who has umpired three World Series and three All-Star games said he’s talked to other active umpires, and, “They feel the strike zone has changed.”

Well, yes, Jim, it has changed: You can’t call balls strikes with impunity any more. 

Taking those strikes out of the game is the single biggest benefit of the challenge system. It’s a huge win for the watchability of baseball and a step in the direction of creating more balls in play. 

The half-life of challenge talk will exceed that of torpedo-bat discourse, in part because of the hot-pink billboards we’ll see a half-dozen times a game all year long. As the season goes on, though, keep in mind that the most interesting parts of the challenge system may be the ones we can’t easily count: The pitches that go unchallenged, and the pitches well outside the zone that are no longer called strikes, and often not even thrown.

Marlins 4, Rockies 3

                 AB  R  H  BI
Caissie PH-RF     2  1  1   2 HR

Owen Caissie wasn’t in the Marlins’ Opening Night lineup until Christopher Morel pulled up lame hours before the first pitch. Dropped into the DH slot, Caissie had an RBI double off lefty Kyle Freeland in a 2-1 Marlins win. He followed that up with three hits Sunday before once again being sent to the bench against a lefty Sunday. Caissie grounded out hitting for Austin Slater in the eighth, then came up with the tying run on second and two outs in the ninth and walked it off. (That’s a great shot of the moment Caissie transitions from “run!” into his home-run trot.)

But for the Morel injury, Caissie might not have started two of the first three games, which is a terrible way to handle a young player. Come to think of it, so is watching him get hits off lefties in his first two games and then sitting him against the next one anyway. We’re seeing this around the league, where Jac Caglianone and Marcelo Mayer were both platooned with fringe veterans in the season’s first weekend. Slater has his uses, but there is no reason for the 2026 Miami Marlins to be getting cute with a player who can become a core piece for them. No left-handed hitter ever learned to hit lefties while watching waiver bait from the bench.

1. Los Angeles Dodgers (98-64, first in NL West, 844 runs scored, 661 runs allowed).

They added a top-15 player and a top-five relief pitcher to the two-time defending World Champions.

The meta aspects of that aside -- you know I’m all for teams competing as hard as they can using any and all tools at their disposal, because their job is to win for their fans, no one else’s -- it makes it hard to do a Dodgers preview. Yes, there are age issues, same as the Phillies, but the Dodgers’ older core is better and their next group of players, your Will Smiths and Max Muncys, is better. The Dodgers worked in Andy Pages last year and will give Alex Freeland a chance to make the team younger this year.  

If MLB were run like the English Premier League, where the champion is the team in first place at the end of the year, no month of max-intensity playoffs to follow, the Dodgers might win 115 games. They could win 120. I would love to watch that. I mentioned in Gaming that no team has won even 100 games since 2023, the product of the structural changes to the sport this decade. I think the Dodgers are a 108-win team that wants to win exactly one more game than it needs to to make the playoffs. As we saw last year, they didn’t seem to even flinch at playing in the first round. 

The Dodgers have spent the last two years playing for October. They didn’t win 100 games in either season, but they went 24-8, a .750 winning percentage, in the playoffs and won two World Series. It’s hard to argue with that kind of success. 

The main concern as they enter 2026 is the pitching. Blake Snell is out for two months, Roki Sasaki is a mess, and Emmet Sheehan is missing a lot of his 2025 velocity. Blake Treinen is somehow still here, likely to outlast all of us. The Dodgers have their usual melange of vaguely familiar names coming back from injury, and we’ll no doubt see Landon Knack and River Ryan and Gavin Stone this year when someone more famous goes on the IL with a blister or heartburn or nightmares. 

The next important game the Dodgers play is more than six months away. Until then, enjoy this incredible collection of baseball talent, and try not to think about what it could do if the rules were better.

Upside: They could set the record for wins, but I’m long past going on #117Watch. They’d probably top out at 112-50 if they wanted to.

Downside: There’s a famous tweet about how the Dodgers look like a juggernaut in April and a jalopy in October. I guess it could happen again, but I’ve baked that it here and projected them at the bottom of their range. They won’t fall past 96-66

Modest Proposal: Give Sasaki, who has looked good for two playoff appearances since signing with the Dodgers, the Roy Halladay treatment. Send him to A ball and let him start over, and don’t think about bringing him to the majors until he’s ready.

4. New York Yankees (94-68, second in AL East, 821 runs scored, 680 runs allowed).

Wednesday night, ESPN’s Jeff Passan referred to the “run-it-back rhetoric” around the Yankees, which stuck in my craw. This isn’t some made-up narrative. The Yankees return their top 11 players from last year by playing time, including every single hitter who played during their postseason run. (Anthony Volpe and Jasson Dominguez didn’t make the Opening Day roster.) Every starting pitcher they used in the playoffs comes back, as well as ten of the 12 pitchers the team used. Hell, the other two, Devin Williams and Luke Weaver, stayed within the city limits. Those are facts, not rhetoric: The Yankees are running back last year’s team as much as any team this century has.

8. New York Mets (87-75, second in NL East, 809 runs scored, 731 runs allowed).

David Stearns moved on from the core he inherited, which wasn’t an unreasonable decision given that core’s age and limitations. In practice, though, he’s built an awkward roster, a mix of free agents and free-agent-like substances, crowding out the products of the strong farm system he inherited. 

However awkward the mix, the Mets are going to score runs. This is the second-best offense in the game, with rookie Carson Benge or trade pickup Luis Robert Jr. the low man, and they’re likely to hang around a 95 wRC+. Juan Soto is at his peak, Bo Bichette brings a much-needed skill set -- singles and doubles to drive home the guys who draw walks -- to Queens, and you’re surely already sick of me talking up Francisco Alvarez.

10. Arizona Diamondbacks (86-76, second in NL West, 801 runs scored, 766 runs allowed).

This year’s winner of the award for Best Tee-Ball Team is...

Offense: fifth
Defense: third
Starters: 23rd
Bullpen: 23rd

You can’t say they haven’t invested in pitching, signing Corbin Burnes, Eduardo Rodriguez, Michael Soroka, and Jordan Montgomery in free agency, and pulling back Zac Gallen and Merrill Kelly from that same pool. They built a pretty good bullpen, the best of which will miss most-to-all of the season with injuries. Maybe you ding them for bad judgment in some of their choices, but who was really against signing Burnes or giving Justin Martinez an extension a year ago.

The Diamondbacks have been better than they are given credit for. They won the NL pennant in 2023, missed the playoffs on a three-way tiebreaker at 89-73 the next year, and had to sell at the ’25 deadline when all their best pitchers got hurt, only to go on a 29-18 run that had them a game out of a playoff berth with five to play. They lost a Calvinball game to the Dodgers, though, then got crushed in a bullpen game, ending their run. 

This core is extremely strong, Corbin Carroll, Geraldo Perdomo, and Ketel Marte each has a top-five MVP finish over the last three years. That group is finally joined by forever prospect Jordan Lawlar, still just 23, and now an outfielder who did post a 14/10 K/BB in spring training. The floor for position players is high, with Alek Thomas plus defensively in center and big defensive upgrades on the infield corners with Carlos Santana and Nolan Arenado. We’ll see how Lawlar works out in left while waiting for Lourdes Gurriel Jr.’s return, but there’s a pretty good argument that the Diamondbacks won’t have a below-average defender on the field most days.

They’ll have to out-hit and out-field their pitching, and I think they can, especially getting Burnes back at midseason and being able to go into the market to add relievers at the deadline. There’s a very small chance they push the Dodgers in the West, and a much higher one they settle into a wild-card berth.

Upside: The MVP candidates all play at that level together in one season, the team leads MLB in runs scored, and they give the Dodgers a fright at 93-69.

Downside: Even a strong defense can’t keep them from giving up 800 runs, and the bad bullpen causes them to lose a lot of close games. They sell at the deadline, but stay in the mix again and finish 81-81.

Modest Proposal: Drey Jameson didn’t pitch well in the Cactus League, earning a trip to Reno in his return from a couple of years lost to elbow issues. I wouldn’t let him get comfortable in the Biggest Little City in the World, as he was throwing 97 in camp and both his slider and change were getting some whiffs. Of the many options to bolster this pen, I like him the best.
