The Milwaukee Brewers acquired left-hander Kyle Harrison, infielder David Hamilton, and pitcher Shane Drohan from the Boston Red Sox on Monday in exchange for third baseman Caleb Durbin, shortstop Andruw Monasterio, third baseman Anthony Seigler, and a Compensation B draft pick, sources told Jeff Passan of ESPN. Harrison, 24, went from the San Francisco Giants to the Red Sox last year in the trade that involved infielder Rafael Devers, and now he's on the move again. The former third-round pick only appeared in 11 games (six starts) for the Giants and BoSox in 2025, posting a 4.04 ERA and 1.37 WHIP with 38 strikeouts and 14 walks in 35 2/3 frames. It wasn't a great sign that Harrison's walk rate sat at 11.8% at Triple-A Worcester last year, but the Brew Crew will try to get more out of him. Harrison will be in the mix for the competition for one of the final rotation spots in Milwaukee in spring training this year.

Boston Red Sox infielder Romy Gonzalez (shoulder) is dealing with shoulder inflammation that popped up during the end of the regular season and got worse in early offseason workouts, according to Chris Cotillo of MassLive.com. Gonzalez said he received a platelet-rich plasma injection 2 1/2 weeks ago. He's currently behind schedule, but the goal remains to be ready for Opening Day. The 29-year-old former 18th-round pick by the Chicago White Sox in 2018 out of the University of Miami slashed .305/.343/.483 with an .826 OPS, nine home runs, 53 RBI, 47 runs scored, and six stolen bases in 96 regular-season games in 2025 in his second year with Boston. Gonzalez had an impressive 99th-percentile hard-hit rate and 123 wRC+ in what was a breakout year, and he also dominated left-handed pitchers with a .331 average. Playing time will be the biggest issue for Gonzalez, who figures to open the season in a utility infield role if he's healthy.

Houston Astros All-Star closer Josh Hader (shoulder) has been throwing lightly and on flat ground as spring training begins for the Astros, according to Buster Olney of ESPN. Hader and the Astros hope to learn more about where he stands in his preparation for the 2026 season in the middle of this week. The 31-year-old southpaw missed the last seven-plus weeks of last season with a left-shoulder strain, but he said earlier in the offseason that he feels "back to normal," and he should be ready for Opening Day, barring a setback in spring training. Hader is a bit more of a risk for fantasy managers entering the 2026 campaign, but with his nasty fastball/slider mix, he showed last year before his shoulder injury that he's still one of the most dominant closers in the game. He held a 2.05 ER and 0.85 WHIP with a 29.1 K-BB percentage, which was fifth among qualified relievers. If Hader has a setback before or during the season, Bryan Abreu would likely be the favorite to take over the closing job in Houston.

Arizona Diamondbacks left-handed reliever Andrew Saalfrank (shoulder) posted a photo of himself on Monday on his Instagram account and announced that he underwent shoulder surgery, according to Alex D'Agostino of Sports Illustrated. MLB.com's Steve Gilbert reports that Saalfrank will miss the entire 2026 season. The 28-year-old southpaw was a key bullpen piece during the team's 2023 run to the World Series. The former sixth-round pick made a career-high 28 relief appearances for the Snakes last year, posting a 1.24 ERA, 1.00 WHIP, his first three career saves, five holds, 19 strikeouts, and 10 walks in 29 innings pitched. Saalfrank's injury is another blow to a banged-up Diamondbacks bullpen that will also be without relievers Justin Martinez (elbow) and A.J. Puk (elbow) for a good chunk of the 2026 season.
