The Athletics designated Spence for assignment Tuesday.

With Scott Barlow and Aaron Civale officially signing one-year deals with the A's on Tuesday, Spence and Grant Holman (finger) will both lose their place on the 40-man roster. Spence made 32 appearances (eight starts) with the Athletics in 2025, turning in a 5.10 ERA and 1.44 WHIP to go with a 66:26 K:BB through 84.2 innings. Assuming he clears waivers, the 27-year-old righty will open the season at Triple-A Las Vegas.

The Athletics designated Holman (finger/shoulder) for assignment Tuesday.

Holman and Mitch Spence will both lose their places on the 40-man roster to make room for new signees Scott Barlow and Aaron Civale. Holman posted a 5.09 ERA and 1.52 WHIP over 23 innings with the A's in 2025 before suffering a season-ending finger injury in June. It's unclear where he stands in his recovery, but he now seems likely to open the new season in the minor leagues.

The Tigers placed Olson on the 60-day injured list Tuesday after he underwent a right shoulder labral repair Feb. 2 that will result in him missing the 2026 season.

It was feared that Olson would not be ready for Opening Day, but it turned out to be worse than that. Near the end of the 2025 season, there was a hope that he could return for the postseason after hitting the injured list in July, but that did not come to fruition either. Prior to the Tigers announcing Olson's surgery, they signed Framber Valdez on Feb. 4 and Justin Verlander earlier Tuesday. Troy Melton is also an option to find time in the rotation with both Olson and Jackson Jobe (elbow) out.

The Tigers placed Jobe (elbow) on the 60-day injured list Tuesday.

Jobe underwent Tommy John surgery in June and will officially open the 2026 season on the injured list while he continues his recovery. The Tigers are hopeful that the 23-year-old righty will be able to return near the end of the regular season, though he may have to wait until 2027 to have a significant impact on the team.

Bieber will have a delayed build-up during spring training and will begin the season on the injured list due to right forearm fatigue, Ben Nicholson-Smith of Sportsnet.ca reports.

After making five appearances in the playoffs -- including Game 7 of the World Series versus the Dodgers -- Bieber reported to have pitched through forearm fatigue late in the year, and he's still not back up to full strength a few months later. The right-hander also made seven regular-season starts last season in his return from Tommy John surgery, and it's not a major surprise he's dealing with some fatigue after an extended playoff run. Manager John Schneider described Bieber as "feeling good," so he may not need too much time on the shelf to begin 2026.

Manager John Schneider revealed Tuesday that Francis is undergoing UCL reconstruction surgery on his right elbow and will miss the 2026 season, Mitch Bannon of The Athletic reports.

Francis dealt with a right shoulder impingement during the 2025 season that landed him on the injured list in June. He was able to commence a throwing program in August after some prior setbacks and had managed to face hitters during live batting practice. However, with the right-hander set for Tommy John surgery, he may not pitch in a game for 12 to 18 months.

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.
