Manager John Schneider said Tuesday that Santander will undergo left labral surgery Wednesday and will miss roughly 5-6 months, Arden Zwelling of Sportsnet.ca reports.

Santander was limited to just 54 regular-season games last year while battling injuries in his left shoulder and back. He said earlier in the offseason that he was feeling much better but later suffered a setback in January while ramping up his hitting progression, per Ben Nicholson-Smith of Sportsnet.ca. The 31-year-old's recovery timeline leaves room for him to return before the end of the regular season, though that isn't likely to happen until after the All-Star break. With Santander out, the Blue Jays will likely rely on Nathan Lukes and Davis Schneider to start in left field for the first half of the season.

Joe agreed to a minor-league contract with the Mariners on Tuesday that includes an invite to big-league spring training.

Joe split last season between San Diego and Cincinnati, posting a .186/.262/.243 slash line in 42 games before being outrighted off the Reds' 40-man roster in August. The 33-year-old offers some defensive versatility but is likely a longshot to make Seattle's Opening Day roster.

Manager Kurt Suzuki confirmed Tuesday that Detmers (elbow) is viewed as a lock for the Angels' Opening Day rotation, Rhett Bollinger of MLB.com reports.

Though Detmers found some success while working as a full-time reliever in 2025 (3.08 xFIP, 20.7 K-BB% in 63.2 innings), Angels general manager Perry Minasian said back in October that the left-hander earned another opportunity to prove he belongs in the rotation. Detmers apparently won't even need to earn his spot in the rotation with a strong showing in spring training; in addition to Detmers, Suzuki said that Yusei Kikuchi and Jose Soriano are also locked in as starters heading into the start of camp, while Grayson Rodriguez (elbow) will clinch a spot if he emerges from the spring healthy. Though he didn't pitch over the final weeks of this past season after experiencing elbow inflammation, Detmers didn't require offseason surgery and looks like he'll be 100 percent at the onset of camp.

Slater agreed to a minor-league contract with the Tigers on Tuesday that includes an invite to big-league spring training, Cody Stavenhagen of The Athletic reports.

Slater split the 2025 campaign between the White Sox and Yankees, and he posted a .216/.270/.372 slash line with five homers in 160 plate appearances during the regular season. The 33-year-old best fits as a short-side platoon player in the outfield, and he could carve out that role in a Detroit outfield that's heavy on left-handed bats.

The Nationals placed Williams (elbow) on the 60-day injured list Tuesday.

The move frees a spot on the 40-man roster for the addition of Andre Granillo, who was acquired via trade from the Cardinals. Williams underwent an internal brace surgery on his right elbow last July and will sidelined for at least the first two months of the season while he continues his rehab.

Stephenson will earn $6.8 million in 2026 after winning his arbitration hearing against the Reds, Gordon Wittenmyer of The Cincinnati Enquirer reports.

The two sides went to a hearing despite just a $250,000 difference in their submitted arbitration figures, and the three-person panel ultimately picked Stephenson's filing. Stephenson put up a .737 OPS with 13 home runs over 88 regular-season contests for the Reds this past season and will be their top catcher again in 2026. He is slated to reach free agency next offseason.

The Nationals acquired Granillo from the Cardinals on Tuesday in exchange for George Soriano, Jeff Jones of the Belleville News-Democrat reports.

Granillo broke into the big leagues in 2025 with a 4.71 ERA and 18:7 K:BB over 21 innings. The 25-year-old has a career 31.9 percent strikeout rate in the minors but has also walked batters at a 12.7 percent clip. Granillo will compete for a spot in the Nationals' bullpen but does have minor-league options remaining.

The Cardinals acquired Soriano from the Nationals on Tuesday in exchange for Andre Granillo, Jeff Jones of the Belleville News-Democrat reports.

Soriano has been bouncing around via waivers this offseason and is now joining his fifth organization of the winter. The right-hander is out of minor-league options, so he's a good bet to open the season in the Cardinals' bullpen. Soriano holds a career 5.95 ERA and 117:55 K:BB across 118 innings at the big-league level.

Angels manager Kurt Suzuki said Tuesday that Manoah will have to earn his place in the starting rotation, Rhett Bollinger of MLB.com reports.

The 26-year-old joined the Halos on a one-year, $1.95 million contract in December, but he was never likely to have much in the form of guaranteed playing time after spending most of 2025 rehabbing from UCL surgery. Manoah should still be the favorite to win a job at the back end of Anaheim's rotation, given the club's other starting options.

Mets president of baseball operations David Stearns said Tuesday that the team is targeting early May for Minter's (lat) season debut, Max Goodman of NJ.com reports.

Minter will get a late start to the season after undergoing left lat surgery last May. It's not clear where the veteran reliever is at in his throwing program, but he will be slow-played during spring training before eventually going out on a rehab assignment. Once healthy, Minter will fill a setup role ahead of closer Devin Williams.
