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.

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 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.

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.

Angels manager Kurt Suzuki indicated Tuesday that Rodriguez (elbow) will have to prove he's healthy and earn his place in the starting rotation, Rhett Bollinger of MLB.com reports.

The right-hander was acquired from the Orioles in November, but the Angels won't immediately guarantee him a spot in the starting rotation. Rodriguez was sidelined all of 2025 due to lat and elbow injuries and has had his fair share of health issues throughout his career. The 26-year-old seems likely to make the rotation if he can stay healthy, but that's hardly a given for the former top prospect.

Verlander agreed to a one-year, $13 million contract with the Tigers on Tuesday, Cody Stavenhagen of The Athletic reports.

The veteran right-hander spent the 2025 campaign in San Francisco, finishing the season with a 3.85 ERA, 1.36 WHIP and 137:52 K:BB across 152 innings. Verlander is now coming back to Detroit, where he won Rookie of the Year, an MVP and a Cy Young Award across the first 13 seasons of his big-league career. He'll turn 43 years old on Feb. 20 and will help round out a Tigers rotation headlined by Tarik Skubal and Framber Valdez.

The Red Sox placed Houck (elbow) on the 60-day injured list Tuesday, Chris Cotillo of MassLive.com reports.

The right-hander underwent a hybrid reconstruction of the UCL in his right elbow, plus a flexor tendon repair, in August, so his move to the 60-day IL was always a matter of time. Houck is targeting late 2026 to rejoin the Red Sox, but it wouldn't be surprising if he's unable to rejoin the major-league roster until 2027.

Civale agreed to a one-year $6 million contract with the A's on Tuesday, Jon Heyman of the New York Post reports.

The 30-year-old right-hander split the 2025 campaign between the Brewers, White Sox and Cubs, finishing the regular season with a 4.85 ERA, 1.26 WHIP and 88:33 K:BB across 102 innings. Civale started in 18 of those 23 appearances last year and is a safe bet to work out of the Athletics' rotation, providing another veteran presence in a unit that's unsettled at the back end.

Ober worked with a specialist much of the offseason after dealing with a nagging hip issue in 2025 and has noticed a "big difference," Dan Hayes of The Athletic reports.

Ober posted a 5.10 ERA over 27 starts last season and saw his average four-seamer velocity tumble from 91.7 mph to 90.3 mph year-over-year. The 30-year-old also lost the command he had been known for, but he is now fully healthy and seems optimistic about a bounce-back season in 2026. Prior to 2025, Ober had a career 3.76 ERA, 1.07 WHIP, 25.6 percent strikeout rate and 5.4 percent walk rate.

Ortiz (personal) will remain on leave and is not permitted to report to spring training, Tim Stebbins of MLB.com reports.

Ortiz and teammate Emmanuel Clase were placed on non-disciplinary paid leave amid allegations of sports gambling last July. The two pitchers were subsequently indicted on charges in November related to an alleged scheme to rig bets on pitches thrown in MLB games. There remains no timeline for a resolution in each case.
