Red Sox trade return: Who are the other two players in addition to Caleb Durbin Boston received?

FORT MYERS — The Red Sox made a six-player trade with the Brewers on Monday, acquiring an everyday infielder in Caleb Durbin.

Durbin — who has the ability to play third base and second base — is the headliner in the three-player return to Boston. But what about the other two acquisitions, Andruw Monasterio and Anthony Seigler?

Seigler and Monasterio each have two minor league options remaining, and so the Red Sox have the ability to send them back and forth between Boston and Triple-A Worcester throughout the 2026 season.

Monasterio, a 28-year-old right-handed hitter from Venezuela, has a chance to make the Opening Day roster if right-handed hitting utility man Romy Gonzalez isn’t ready. Gonzalez received a PRP injection for left shoulder inflammation two and a half weeks ago and hopes to be ready for the start of the regular season.

Monasterio appeared in 219 games for the Brewers from 2023-25. He went 34-for-126 (.270) with a .319 on-base percentage, .437 slugging percentage and .755 in 68 games last season.

“We think that Andruw is an above-average defender at multiple positions,” chief baseball officer Craig Breslow said. “He’s played second base, he’s played third base, he’s played shortstop. Also as a right-handed hitter, he’s had some success against lefties. An OPS over. 800 against lefties last year.”

The utility man has recorded six defensive runs saved in 392 ⅓ innings at second base as a major leaguer. He has four defensive runs saved in 671 innings at third base.

He went 12-for-44 (.273) with a .360 on-base percentage and .477 slugging percentage against lefties last year.

“Giving us another option who can play the infield and be in a lineup against left-handed pitching is something that is important for us and he’s kind of served that role very, very well in a couple of seasons with the Brewers,” Breslow said.

Seigler was a 2018 Yankees first-round draft pick (23rd overall) out of Cartersville High in Cartersville, Georgia. The 26-year-old left-handed hitting infielder made his MLB debut for Milwaukee last year. In 34 games for the Brewers, he went 12-for-62 (.194). He made all 16 of his starts at third base and also appeared in one inning at first base and one inning at catcher.

He has batted only .230 with a .369 on-base percentage, .370 slugging percentage and .739 OPS in 451 games in the minors but he had a strong season at Triple-A Nashville last year. In 72 games, he batted .285 with a .414 on-base percentage, .478 slugging percentage, .892 OPS, eight home runs, 16 doubles and four triples (307 plate appearances).

“A guy that has moved around a little bit,” Breslow said. “I think he can play second base, can play third base.”

Seigler does have some experience at second base, playing 163 games there in the minors.

“As a left-handed bat, can hit right-handed pitching and is coming off a really good season in Triple A,” Breslow said. “I think he maybe hasn’t gotten an extended look in the big leagues and a chance to show just how talented he is. But if you look at the pedigree and you look at the season that he just had, it’s pretty easy to get excited about him.”

Durbin is a right-handed hitting third baseman/second baseman who finished third for the 2025 NL Rookie of the Year. While the 5-foot-7, 183-pounder slugged only .387 with 11 homers in 136 games (506 plate appearances) for the Brewers in 2025, he’s a solid contact hitter. He finished in the 98th percentile in strikeout percentage (9.9%), 96th percentile in whiff percentage (13.0%), 95th percentile in squared-up percentage (33.3%) and 72nd percentile in chase percentage (24.6%).

“Just watching him from afar in that series (at Milwaukee) last year, he was a pain in the butt,” Cora said. “Put the ball in play, made some good decisions. He’s a good base runner, too.”
