The Pink Sox and Brewers pulled off a six-player commerce on Monday. Boston acquired infielders Caleb Durbin, Andruw Monasterio and Anthony Seigler, in addition to Milwaukee’s Aggressive Steadiness Spherical B choose in trade for pitchers Kyle Harrison and Shane Drohan and infielder David Hamilton. All six gamers in query have been on their golf equipment’ 40-man roster, so no corresponding strikes have been needed.
Durbin is a notable pickup for the Boston infield and needs to be penciled in for on a regular basis at-bats — presumably at third base, although he also can deal with second base if the Pink Sox desire Marcelo Mayer on the scorching nook from a defensive standpoint. The 25-year-old Durbin (26 in a pair weeks) completed third in Nationwide League Rookie of the Yr voting in 2025 after he batted .256/.334/.387 with 11 dwelling runs, 25 doubles, 18 steals (24 makes an attempt), a 5.9% stroll charge and a tiny 9.9% strikeout charge. He turned in above-average marks for his glovework at third within the estimation of each Defensive Runs Saved (5) and Outs Above Common (2).
He’s not the massive middle-of-the-order presence many Sox followers have coveted, however Durbin is an reasonably priced, controllable and versatile defender who’ll additional the Pink Sox’ pivot towards run prevention and assist to decrease a crew strikeout charge that was Tenth-highest within the sport final yr at 22.9%. He’s a right-handed hitter whose pull proportion (43.3%) is a bit larger than league common (40.6%), which ought to play nicely with the Inexperienced Monster at Fenway Park. Durbin involves the Pink Sox with 5 full seasons of membership management and two minor league possibility years remaining (not that there’ll be any considered optioning him to the minors anytime quickly after final yr’s sturdy efficiency).
If Durbin is ticketed for the recent nook, that’ll go away second base to a mixture of the left-handed-hitting Mayer and righty-swinging Romy Gonzalez. Not too long ago signed utilityman Isiah Kiner-Falefa can again up each these positions in addition to shortstop.
The 28-year-old Monasterio might additionally think about at both second or third base, though like Gonzalez and Kiner-Falefa, he’s a right-handed hitter. As is the case with Gonzalez, Monasterio additionally carries notable platoon splits. He’s a profession .255/.352/.375 batter towards lefties however a .246/.303/.338 hitter towards fellow righties. He’s coming off a career-best exhibiting within the majors — albeit in a restricted pattern of 135 plate appearances — having slashed .270/.319/.437 (111 wRC+) with 4 homers. He’s controllable for an additional 4 seasons and gained’t be arbitration-eligible till a minimum of subsequent offseason (probably later, relying on how a lot time he spends within the minors this yr).
Monasterio additionally has practically 3500 skilled innings at shortstop underneath his belt, so he provides Boston one other backup choice to oft-injured Trevor Story at shortstop (alongside Kiner-Falefa). He additionally has a full slate of three minor league possibility years remaining, so there’s no assure he’ll open the season on Boston’s main league roster. He’ll have the chance to win a job in camp, however barring harm and/or commerce, Boston’s bench appears prone to embody Gonzalez, Kiner-Falefa, catcher Connor Wong and outfielder/designated hitter Masataka Yoshida.
All of that assumes that Mayer makes the Opening Day roster, nevertheless it’s attainable that the previous No. 4 total choose might open the season in Triple-A Worcester, too. Mayer’s .228/.272/.402 slash was nicely under league-average in 2025, however he solely turned 23 in December and has a formidable minor league monitor report. That features a .271/.347/.471 exhibiting in Triple-A final yr. He’ll have each alternative to win a beginning job in camp with the Pink Sox, however late additions of Durbin and Kiner-Falefa reduce the crew’s reliance on the nonetheless largely untested prime prospect.
Boston additionally picks up the 26-year-old Seigler, who’ll present some depth within the higher minors and could possibly be a steadily used bench piece over the course of the approaching season. He’s batted simply .194/.292/.210 in an insignificant pattern of 73 main league plate appearances, however Seigler hit .285/.414/.478 with eight homers, 16 doubles, 4 triples, 23 steals (27 makes an attempt), a 16.9% stroll charge and a 19.2% strikeout charge in 307 Triple-A plate appearances this previous season. He’s been used as an infielder (second base, particularly) much more steadily than a catcher in latest seasons as a result of troubles controlling the run sport and a susceptibility to handed balls.
Even when he’s hardly ever deployed behind the plate, Seigler is on the very least an fascinating third catcher possibility who is also comfy at second base and third base. He has two minor league possibility years remaining and doesn’t actually have a full season of main league service, making him controllable for a minimum of the following six full seasons.
The Pink Sox additionally add a Aggressive Steadiness draft selection — the one picks permissible to be traded underneath MLB guidelines. Milwaukee’s Spherical B choice is the primary in that spherical, presently 67th total (though that might change by a spot or two relying on what occurs with Zac Gallen, the ultimate remaining free agent who rejected a qualifying supply and is thus topic to draft choose compensation). They’ll not solely get so as to add an additional participant however may also add that choice’s slot worth to their draft bonus pool. Final yr’s No. 67 choice got here with a $1.285MM worth. This yr’s needs to be up from {that a} bit. The Pink Sox don’t must spend that quantity on this choose particularly; the slot worth can be added to their bonus pool, which they will freely divide up amongst their picks how they see match.
Turning to Milwaukee’s aspect of the swap, it appears like a precursor to a different acquisition. The Brewers not solely traded their incumbent starter at third base — they traded two of the highest depth choices behind him in the identical swap. Maybe there’s some infield shuffling on the horizon, nevertheless it feels just like the Brewers might want to add some assistance on the filth. Hamilton might see reps on the scorching nook this spring however has spent much more time at second base within the Pink Sox group. Shortstop Joey Ortiz and second baseman Brice Turang are plus defenders who might each slide one place over to the left, however doing so may weaken the general defensive aptitude of the group.
Bringing in some assist at third base appears prudent, however choices there are few and much between. Time will inform if president of baseball operations Matt Arnold has one other transfer up his sleeve, however for proper now, the Brewers look skinny at third base.
Their pitching depth, nevertheless, continues to develop — even after buying and selling ace Freddy Peralta to the Mets final month. In the present day’s commerce brings in a pair of massive league-ready arms. Harrison, 24, already has 42 huge league video games (37 begins) underneath his belt. He’s pitched to a 4.39 ERA with a 22.9% strikeout charge and eight% stroll charge in that point.
In the intervening time, Harrison profiles as a fifth starter possibility for the Brewers, however he carries extra upside than most back-of-the-rotation candidates. The 2020 third-round choose ranked as one of many prime minor league abilities in all of baseball for a number of years, peaking because the No. 26 prospect in your entire sport on Baseball America’s top-100 previous to the 2023 season. He’s but to place all of it collectively within the majors, however Harrison has fanned higher than 30% of his opponents in elements of two Triple-A seasons.
The Brewers have developed a popularity as one of many sport’s prime “pitch labs.” They labored wonders with righty Quinn Priester in 2025 and have helped to facilitate turnarounds or breakouts from relievers like Trevor Megill, Joel Payamps, Bryse Wilson, Colin Rea, Nick Mears, Jared Koenig and others. There are many parallels between Priester’s trajectory and that of Harrison; each have been former prime prospects traded to Boston and rapidly buried on the Pink Sox depth chart. The Brewers will hope to transform on that very same profile for a second consecutive season now.
Drohan simply turned 27 final month, making him outdated for a “prospect,” however he nonetheless sat fifteenth on Baseball America’s latest replace of Boston’s system. His path to huge leagues has been slowed each by harm and a range within the Rule 5 Draft. The White Sox took Drohan again in 2023 after Boston left him unprotected. He required a nerve decompression surgical procedure in his shoulder that spring, nevertheless, which restricted him to 16 1/3 rehab innings that season. A forearm harm in 2025 restricted him to 54 minor league frames.
When he’s been wholesome, Drohan has appeared the a part of an fascinating prospect. His Triple-A numbers are skewed by a tough exhibiting late in 2023 and through some rehab work in 2024 — each probably impacted by his shoulder — however he was wonderful final season, tossing 47 2/3 innings with Worcester and recording a 2.27 ERA, a 35.3% strikeout charge, an 8.4% stroll charge and a large 17.3% swinging-strike charge. He additionally posted a 2.17 ERA in elements of two Double-A seasons and was a part of the 2023 Futures Recreation. Drohan sat 93.3 mph along with his four-seamer in Triple-A in 2025, complementing the pitch with an 84.7 mph slider, an 88.8 mph cutter, an 84.3 mph changeup and a 77.9 mph curveball (listed so as of utilization charge).
Hamilton, 28, returns to the membership that initially drafted him however traded him to Boston as a part of 2021’s Hunter Renfroe swap. He’s performed in elements of three seasons with Boston and totaled 550 plate appearances with a .222/.283/.359 batting line.
Hamilton hasn’t hit a lot however is a plus runner with ninety fifth percentile dash pace, per Statcast, and 57 profession steals in 68 makes an attempt (83.8%). On a charge foundation, he’s been one of many sport’s elite defensive second basemen throughout his time within the majors, piling up 16 Defensive Runs Saved and eight Outs Above Common in solely 679 innings.
The Brewers initially drafted Hamilton within the eighth spherical of the 2019 draft out of the College of Texas. Arnold and prime lieutenants like AGMs Matt Kleine, Will Hudgins and Karl Mueller have been all within the Milwaukee entrance workplace after they first signed Hamilton out of the draft. That familiarity with him each as a participant and as an individual presumably performed a job on this morning’s commerce.
Adam McCalvy of MLB.com reviews that Hamilton will see loads of reps at third base this spring. Whether or not his stellar second base protection carries over to 3rd base and whether or not Hamilton performs nicely sufficient to safe a job will decide his roster standing come Opening Day. He has a minor league possibility yr remaining, so if the Brewers do make one other acquisition or if Hamilton merely struggles to an important sufficient extent this spring, he may be despatched to Triple-A Nashville while not having to move by waivers. The Brewers can management him for a minimum of 4 extra seasons — 5 if he spends greater than 25 days within the minors this yr.
For the Pink Sox, at this time’s commerce appears to largely spherical out the infield. With Kiner-Falefa additionally aboard as a glove-first utility possibility, there doesn’t look like far more room so as to add. Durbin needs to be an improve of a pair wins, and his excessive put-the-ball-in-play method and defensive aptitude ought to assist to lift Boston’s flooring fairly a bit, even when the offense as a complete seems to be suspect past the highest few hitters.
The Brewers are actually 10 to 12 deep of their rotation combine, which might set the stage for an additional commerce. They might additionally merely maintain onto that depth, figuring out they’ll want a military of pitchers to get by a 162-game season and that lots of their present arms have lower than a full yr of expertise within the majors, however some type of extra infield depth appears prone to be on the horizon after at this time’s commerce thinned them out.
Jeff Passan of ESPN was first to report Durbin, Harrison, Drohan and Hamilton’s inclusions. Will Sammon of The Athletic first reported Seigler, Monasterio and the draft selection.
