Craig Breslow seems to love himself a last-minute, big-time addition for spring training. Last season, he agreed to a three-year deal with Alex Bregman after camp was underway. This year, he swung a three-for-three player trade with the Milwaukee Brewers mere hours before pitchers and catchers reported to Fort Myers.
In a deal seemingly out of nowhere, Breslow traded LHP Kyle Harrison, LHP Shane Drohan, and INF David Hamilton to the Brew Crew for INF Caleb Durbin, INF Andruw Monasterio, and UTIL Anthony Seigler along with a Competitive Balance Round B draft pick that will fall around No. 67 overall. Arguably the most interesting part of the trade is the Brewers have traded their entire third base depth to Boston in exchange for two mostly unproven pitchers and a utility man who offers little outside of speed on the basepaths. That sounds like an absolute fleece for the Red Sox.
Kyle Harrison was the biggest part of the return of the Rafael Devers trade. I’m not going to sit here and rehash that at all — our own @Maddie Landis has done an excellent job breaking down that trade tree here — but there is now only one part of that deal left in the organization, and Jose Bello won’t be sniffing the major leagues any time soon. Shane Drohan was returned to the Red Sox after he failed to stick on the 40-man roster of the White Sox after he was selected in the 2023 Rule 5 Draft. We don’t need to go into detail on Hamilton but we now no longer have to suffer his defensive lapses and his lack of production at the plate. Sure, he could swipe a bag, but his profile became entirely superfluous once Isiah Kiner-Falefa was signed.
Diving under the hood on the return to Boston, we see why the Red Sox were eager to make this deal. Durbin finished third in the National League Rookie of the Year voting last season. He slashed .256/.334/.387 with 11 home runs, 53 RBIs, and 18 stolen bases. He led the National League in hit by pitches as well, so he’s not afraid to get on base by any means necessary. He was viewed as the third baseman of the future with the Brewers but will likely shift to second base in Boston so Marcelo Mayer can man the hot corner.
Now, the team has options as second and third base between that duo plus Kiner-Falefa being able to spell pretty much the entire infield when necessary. What likely made Durbin even more interesting for the Red Sox though, is that he had a PullAir% of 20.4% in 2025. When the team traded for Willson Contreras in December, his 19.8% PullAir% was cited as one of the main reasons he made sense for the team. Now, we have a much younger, more controllable infielder with an even more tantalizing profile in the fold. An interesting winkle here is that Durbin’s home spray chart is tailor made for Fenway Park. He hit seven of his 11 home runs at home last year. If we overlay that chart over Fenway, we add nine additional home runs to his total. He’s not a slugger by any means, but taking aim at the Green Monster will likely add more homers to his overall total and increase the number of doubles, and maybe even triples, that he has season after season.
In addition to Durbin, Monasterio and Seigler both profile as utility players. Monasterio played first, second, third, shortstop, and left field in 2025 while handling left-handed pitchers fairly well. He slashed .273/.360/.477 against lefties last season. He can insert into the lineup, along with Romy Gonzalez, against left-handed pitching to give guys like Mayer a break against tough matchups.
Seigler can play second, third, and catcher. He slashed .285/.414/.478 in 72 games in Triple-A last season. In one trade, the Red Sox replenished what was considered their weakest position player group. Breslow swung big here, and at least so far, seems to have really taken advantage of the Brewers. The Red Sox have spent the offseason circling around a multitude of different infielders that didn’t make much sense for the construction of the big-league club. With Caleb Durbin though, the team gets a controllable young infielder with a high floor. He also fits the timeline of the current youth movement in the organization and should prove to be a building block in the infield.
It’s always tough to correctly say that a team has fleeced the Brewers — just look at the Quinn Priester deal from last season — but this feels like an overwhelming win by the Red Sox. Factor in an additional draft pick that essentially replaced the pick they lost by signing Ranger Suarez, and the team has an incredibly bright future ahead of them. Baseball season is here and the Red Sox look like a team that’s ready to compete for the AL East.
