Jacob deGrom Is a Litmus Test for Hall of Fame Voters

Earlier this week, my colleague Jay Jaffe touched a bit on Jacob deGrom and his Hall of Fame case. Since the world can always use more sentences describing how awesome deGrom is, and because I’m fascinated by how his Hall of Fame case will look to voters sometime in the mid-2030s, I decided to dig a little more into his future candidacy and reasonable expectations for what the end of his career can add to his record. I also wanted to explore what deGrom’s case means for 2010s/2020s Hall of Fame starting pitcher representation more broadly.

This has been a concern of mine for a while, and I talked a bit about it last year in the context of Chris Sale’s marvelous comeback season. This piece has stuck with me as it was one of those rare articles in which the act of writing it changed my opinion somewhat. At the start, my thought process was “with a less than 50% chance of finishing with 200 wins, Sale probably won’t be in the Hall of Fame, and may be too borderline for even me.” But then I projected the rest of the league, and for the first time ever in ZiPS, not a single pitcher who hadn’t already passed 200 wins was projected to have a 50% chance of reaching that milestone. So, perhaps Sale should get to Cooperstown even if he falls short of that threshold, because if the writers don’t vote for him on the grounds that he didn’t get to 200 wins, how could we justifiably elect any future starting pitcher?

When I wrote last year’s piece, there were only 11 pitchers between 100 and 200 wins, a shockingly tiny number. And of those 11, only one is in a better position to win 200 games now than he was then: Sonny Gray, who has added 12 wins and is having a fairly typical season by his standards. As far as the other 10 are concerned… Gerrit Cole is out until well into 2026 due to elbow surgery, and Sale has missed a bunch of time this year from injuries. Lance Lynn and Kyle Gibson have both since retired, Johnny Cueto has all but officially done the same, and Carlos Carrasco and Dallas Keuchel are in the minors and, for the purposes of this exercise, might as well be retired. Wade Miley has one win this season and is currently out with forearm pain in his comeback from Tommy John surgery. Yu Darvish, who didn’t make his season debut until July, has moved only two wins closer to 200 in his age-38 season. As a Baltimore native, I’m not psychologically prepared to talk about Charlie Morton’s progress.

The good news is eight new pitchers have joined the 100-win club this season, but none of them look to be on a path to 200 wins right now.

Of these eight, only Nola projects with a 50% chance to get to even 150 wins. While it’s theoretically possible for most of the eight to get to 200 wins, it would require an unusually robust late-career surge. During the Wild Card era, only 10 pitchers have amassed 90 wins after their age-34 season, and almost all of them were in the early part of the era; pitcher workloads have continued to drop, and starting pitchers get fewer decisions than ever.

ZiPS projects only four other pitchers to have a 50% shot at reaching 150 wins: Tarik Skubal, Garrett Crochet, George Kirby, and Paul Skenes.

Rewind ZiPS a decade, and it gave 17 active pitchers a 50% chance to win 200 games. Nine eventually did hit that milestone, and Cueto, the only member of the other eight who is still technically active, isn’t going to do it.

So, let’s run the ZiPS projections for the remainder of deGrom’s contract with the Rangers, beginning in 2026 and running through 2028 — assuming Texas picks up his club option for that season. ZiPS was really worried about his health entering the season, for very obvious reasons, and while he just missed his most recent scheduled start due to shoulder fatigue, the injury is not believed to be a long-term issue. His projected workloads in future seasons have increased now that he’s stayed mostly healthy in 2025.

Give deGrom the 21 projected wins for 2026-28 and a couple September wins this year, and that gets him to 123 for his career. In his piece, Jay brought up Sandy Koufax while discussing deGrom, and I think it’s an apt comparison.

Koufax’s peak was more concentrated and more impactful in individual seasons than deGrom’s, but as I said about Johan Santana when he was on the Hall of Fame ballot, if your best years are being mentioned in conversation with those of Koufax, you must have been a dynamite pitcher. To me, from a pure dominance perspective, Peak deGrom isn’t that far behind Peak Koufax; certainly, the gap isn’t wide enough to keep deGrom out of Cooperstown considering pretty much everyone views Koufax as a no-doubt, inner-circle Hall of Famer.

Of course, it’s an inauspicious sign for deGrom that I’m using Santana as the other not-quite-Koufax comp, given that Santana went one-and-done on the ballot. But I’m hopeful that time is on deGrom’s side here. Santana was knocked off the ballot in the 2018 election, and the demographics of BBWAA members who stick around long enough to earn a Hall of Fame vote have changed a lot over the last decade. In fact, the BBWAA didn’t open up membership to internet-based writers — a group that tends to be more versed in analytics — until after the 2007 season, and many of these stathead members couldn’t vote when Santana was eligible. That will be different by the time deGrom hits the ballot in roughly eight or so years.

By then, it’ll be nearly 20 years of writers seeing starter workloads change, and maybe voters will have figured out how to account for the fact that the role of a starting pitcher is very different in the 2020s than it was in the 1990s, let alone in the days of Old Hoss Radbourn. The trio of former Cy Young winners in their 40s — Justin Verlander, Max Scherzer, and Zack Greinke — will likely be in Cooperstown by the time deGrom hits the ballot. Clayton Kershaw is only three months older than deGrom, but considering the Dodgers icon debuted six years earlier, it feels all but guaranteed that he will be the first of the two to retire, meaning he will also enter the Hall before deGrom becomes eligible. If that happens, Kershaw will be the last of his kind to be voted in by the writers, setting the stage for a new standard for starters to make it to Cooperstown. That is, unless Kershaw is to be the last-to-debut Hall of Fame starting pitcher.

I can’t imagine that will be the case, but it is true that over the next decade, the BBWAA has some interesting philosophical questions to answer about the nature of starting pitcher greatness. I’m not sure what those answers will be, but I do know that deGrom will be instrumental in determining them.
