Who is he and where did he come from?
Caleb Durbin is an infielder who played college baseball at D-3 Washington University (in St. Louis) and was drafted by the Atlanta Braves in the 14th round of the 2021 draft. He was traded from Atlanta to the Yankees
after the 2022 season for Lucas Luetge, and then again to Milwaukee after the 2024 season as part of a package that landed Devin Williams. A year later, Durbin comes to the Red Sox from the Brewers, along with fellow infielders Anthony Siegler and Andruw Monesterio and the 67th draft pick (Comp B), in return for pitchers Kyle Harrison and Shane Drohan, and infielder David Hamilton.
Is he any good?
It depends on where you’re setting your expectations. If you’re looking for the middle-of-the-order power bat that Craig Breslow stressed was a top need on multiple occasions, you’re not going to find that with the 5’7”, 183 lb. Durbin.
What you will find is someone with an average-to-plus hit tool, who can make the plays defensively at multiple positions, with a lot of speed on the bases. Durbin slashed .256/.334/.387 in his rookie season, with 11 home runs and 18 stolen bases, which led to third place in Rookie of the Year voting.
The ball is usually put into play when Durbin is at the plate. He was one of only five qualified hitters in all of MLB who had less than a 10% strikeout rate (9.9%), but also had just a 21st percentile walk rate (5.9%). On Monday, Breslow noted Durbin’s Air Pull%, which is well above average at 20.4%. For a right-handed hitter at Fenway, that’s never a bad thing, both for home runs and for doubles.
Defensively, Durbin started 119 games at third base, but just three games at second base for the Brewers in 2025. He was a +5 in Defensive Runs Saved at 3B, but was exactly in the middle of the range with a “0” in Outs Above Average on Statcast. He can also play shortstop in a pinch. With an emphasis on a staff filled with groundball pitchers, Durbin should be part of an improvement on the defensive side in 2026.
TL;DR, just give me his 2025 stats.
136 G, 506 PA, .256/.334/.387, 11 HR, 53 RBI, 60 R, 18-for-24 SB, 5.9 BB%, 9.9 K%, 105 wRC+, 2.6 fWAR
Show me a cool highlight.
Here’s a walk-off homer by Durbin against the Padres on June 7th of last year. And, really, what’s better than a walk-off homer?
What’s he doing in his picture up there?
He’s getting hit by a pitch, something that Durbin can do with the best of them. He led the National League with 24 HBPs a season ago. While that may seem like a flukey stat, there is an art to getting hit by a pitch. If you have ever had a teammate who got hit by a ton of pitches and always found a way to make it look like an accident, you know what I’m talking about. Durbin had double-digit HBPs in each of his three minor league seasons, in significantly fewer plate appearances.
In fact, the Red Sox have brought the top two in HBP over from the NL, as new first basemen Willson Contreras was hit by 23 pitches a year ago. Is it possible that this was intentional?
In Durbin’s case, as mentioned earlier, his 5.9 BB% was in the bottom quarter of the league. But what if you include his 4.7 HBP%? A “walk rate” of 10.6% doesn’t sound so bad, and it’s a higher rate than Durbin strikes out at. In general, hit batsmen happened on 1.1% of the plate appearances in MLB in 2025, and Durbin was drilled at more than 4X that rate.
What’s his role on the 2026 Red Sox?
There were no definitive answers on day one from Red Sox executives, nor Alex Cora. It seems like Durbin would slot in at either second or third base, with Marcelo Mayer playing at the other spot. Upon prospect graduation, the 6’3”, 188 lb. Mayer had a 60-grade arm on Baseball America, where Durbin had a 50-grade arm. My best guess is that Mayer, with more size and a bigger arm, will play third base with Durbin starting at second, a position that he played the majority of the time coming up through the minor leagues. When left-handers are on the mound, Mayer may take a seat in favor of second baseman Romy Gonzalez, which may slide Durbin over to third base on those days. Roster Resource currently projects Durbin to hit seventh in the lineup behind Carlos Narvaez and ahead of Mayer, at least against RHP.
