Gonzalez dealt with left shoulder inflammation much of the offseason and is expected to be limited at the start of spring training, Tim Healey of The Boston Globe reports.

Gonzalez initially injured his left shoulder in the final series of the regular season against the Tigers back in September before going 1-for-9 at the plate in the wild-card series loss to the Yankees. Gonzalez didn't require any sort of offseason surgery but did receive a PRP injection after experiencing discomfort after swinging the bat in January. Gonzalez is aiming to be ready for Opening Day and is once again expected to fill a utility role for Boston this season.

The Rays signed Martinez to a one-year, $13 million contract Monday, Jon Heyman of the New York Post reports.

Martinez will turn 36 years old later this summer and pitched in 40 games for the Reds last season, making 26 starts. He posted a 4.45 ERA, 1.21 WHIP and 116:42 K:BB across a career-high 165.2 innings. Capable of starting or working out of the bullpen, Martinez is expected to be part of the Rays' rotation, Bob Nightengale of USA Today reports.

Duran might not start against left-handed pitchers this season, Chris Cotillo of MassLive.com speculates.

The Red Sox haven't been able to trade from their glut of outfielders this offseason and appear motivated to give Wilyer Abreu an opportunity to play every day, which means Duran could get squeezed out of an everyday role. The left-handed-hitting Duran slashed only .211/.260/.340 over 209 regular-season plate appearances against southpaw hurlers in 2025.

The Red Sox acquired Seigler in a trade with the Brewers on Monday, Mark Feinsand of MLB.com reports.

Seigler hit .194/.292/.210 in 34 games with the Brewers in 2025 but posted a .414 on-base percentage during his time at Triple-A Nashville. The 26-year-old offers unique positional versatility with an ability to play third base, second base, both corner outfield spots and catcher. Seigler has minor-league options remaining and seems likely to begin the 2026 campaign at Triple-A Worcester.

The Red Sox acquired Monasterio on Monday in a trade with the Brewers, Mark Feinsand of MLB.com reports.

Monasterio offers a steady glove at multiple infield spots and he improved offensively with the Brewers in 2025, slashing .270/.319/.437 with four home runs over 68 regular-season contests. The 28-year-old enters a crowded infield picture for the Red Sox and will most likely open 2026 in a reserve role.

The Red Sox acquired Durbin (elbow), Andruw Monasterio, Anthony Seigler and a Comp B pick from the Brewers on Monday in exchange for Kyle Harrison, David Hamilton and Shane Drohan, Jeff Passan of ESPN.com reports.

Durbin had a solid rookie season in Milwaukee, slashing .256/.334/.387 with 11 home runs and 18 stolen bases over 136 regular-season contests. Slated to turn 26 later this month, Durbin mostly played third base for the Brewers and that could be where he slots in for the Red Sox, but he's also an option to handle second base. Durbin underwent arthroscopic elbow surgery in October but should be ready to go for the beginning of spring training.

Oviedo's fastball improved significantly upon his return from elbow surgery in 2025, Mike Petriello of MLB.com reports.

Surface indicators aren't particularly kind to Oviedo, but the Red Sox took a deeper dive and liked the direction of the right-hander's fastball. Prior to undergoing Tommy John elbow surgery in 2024, Oviedo had a decent-enough campaign over 177.2 innings for the Pirates in 2023. That's when he finished 11th in MLB with a plus-11 Run Value on his slider. His fastball, however, was at the other end of the spectrum, minus-10 (178th out of 179 qualified starters). Oviedo's four-seamer had respectable velocity (96 mph) but poor vertical movement. Upon his return in 2025, both metrics showed significant improvement. The pitch that allowed a .275 batting average and .465 slugging percentage in 2023 dropped to .149/.383, while its Whiff rate climbed from 18.5 percent to 31.3. Its Stuff+ metric rose from 82 in 2023 to 115 last year. The Red Sox believe they're getting in on Oviedo at the right time, but it's important to note the small sample size in 2025 -- just 40.1 innings -- and that Oviedo's already troublesome walk rate (4.2 BB/9 in 2023) ticked higher to 5.1 in 2025.

Berrios (elbow) doesn't have a clear path to a spot in the Blue Jays rotation to begin the season, Keegan Matheson of MLB.com reports.

Berrios endured a tough 2025, finishing the regular season on the IL due to a sore elbow and then getting left off the postseason roster. The veteran right-hander has made 30-plus starts in five straight seasons, with last year's 166.0 innings representing his lowest total for a full campaign since 2017 with Minnesota, but Toronto's offseason moves to bring in Dylan Cease and Cody Ponce seem to have Berrios ticketed for the Opening Day bullpen. He still has three years and $67 million left on his contract as well, which will make him tough to trade given his mediocre 4.17 ERA, 1.30 WHIP and 11.8 percent K%-BB% in 2025. With Shane Bieber (forearm) and Trey Yesavage both having potential workload concerns, however, Berrios could still end up getting plenty of starts in 2026 while filling a swingman role.

Akin lost his arbitration case against Baltimore and will earn $2.975 million during the 2026 season, Mark Feinsand of MLB.com reports.

Akin had filed for $3.375 million. The lefty reliever is expected to be one of the Orioles' top setup men in 2026 after finishing last year with eight saves, 16 holds and a 3.41 ERA in 64 appearances.

Volpe (shoulder) will begin the 2026 season on the injured list and is unlikely to be ready to play "at least until May," Randy Miller of NJ.com reports.

Volpe underwent left labrum surgery last October and is still in the recovery phase. This isn't a new timeline for him -- Bryan Hoch of MLB.com reported in early December that Volpe isn't likely to play in April -- but rather serves as a reminder for fantasy managers that the young shortstop is going to miss a substantial chunk of time early in the campaign. Jose Caballero seems to be the leading candidate to get the most starts at shortstop until Volpe is back in action.
