Uceta underwent an MRI on his injured right shoulder Thursday, Marc Topkin of the Tampa Bay Times reports.

Uceta had a setback with the shoulder when he played catch Thursday, so he had imaging done and will see a doctor Friday. Even if he doesn't have any structural damage in the shoulder, it will take him time to get ramped up, putting his Opening Day availability in doubt. When healthy, Uceta is expected to be in the mix for saves in the Rays bullpen.

Gipson-Long (oblique) is scheduled to throw a bullpen Friday, Evan Woodbery of MLive.com reports.

Gipson-Long has been dealing with a strained left oblique early in spring training but is making progress in his recovery. The right-hander appeared in eight regular-season games for Detroit in 2025, making three starts. He figures to open the campaign at Triple-A Toledo.

Simpson will not play in the Rays' first several Grapefruit League games due to a tight left hamstring, Marc Topkin of the Tampa Bay Times reports.

Much of Simpson's value comes from his speed, so the Rays will proceed cautiously with any lower-body issue. The 25-year-old is in line to be the team's primary left fielder this season. He slashed .295/.326/.345 with 44 stolen bases over 109 contests last season as a rookie.

Cardinals manager Oliver Marmol said Friday that O'Brien will be shut down for a few days due to a mild right calf strain, Brian Murphy of MLB.com reports.

It will take a couple weeks for O'Brien to ramp things back up, so it will be at least the beginning of March before he's ready to pitch in spring training games. O'Brien is also now unlikely to pitch for Team South Korea in the World Baseball Classic, though he will remain in the player pool in case there's a chance he can be added later. The injury could also affect O'Brien's chances at opening the season as the Cardinals' closer. He is in the mix for saves with JoJo Romero and perhaps Matt Svanson.

Berrios has appeared to be fully healthy to begin spring training, Keegan Matheson of MLB.com reports. "Jose is fully healthy. He's looked sharp," manager John Schneider said Thursday on TSN 1050's OverDrive. "His stuff is back to where it was probably two years ago in terms of velocity and his breaking ball."

The veteran right-hander is coming off a rough 2025 campaign in which he threw just 166 innings, his lowest total in a full MLB season since 2017. Berrios didn't pitch in the final week of the regular season or in the playoffs due to elbow trouble, but the Blue Jays will need him to be healthy to start 2026 with Shane Bieber (forearm) set to begin the year on the shelf. Berrios posted a 3.63 ERA and 1.17 WHIP over 382 innings from 2023-24, and him regaining that form would provide a big boost to Toronto's rotation.

Alexander is likely to be the Orioles' Opening Day second baseman in place of the injured Jackson Holliday (hand), Brendan Mortensen of MASNSports.com reports.

Holliday will begin the season on the injured list following hamate surgery, though his absence could be relatively brief. Jordan Westburg (elbow) had been under consideration for a move from third base to second base, but he's now shelved himself for at least the first month of the season. Acquired from the Diamondbacks via trade earlier this month, Alexander slashed .230/.323/.383 with seven homers and four steals over 74 games in 2025.

Mayo could be the Orioles' Opening Day third baseman following an injury to Jordan Westburg (elbow), Brendan Mortensen of MASNSports.com reports.

Westburg is set to miss at least the first month of the season due to a partially torn UCL in his right elbow. Mayo was primarily a third baseman in the minors before the Orioles had him focus mostly on first base last season. However, there is a clear need at the hot corner now, so the 24-year-old is in line to return to his old position. Mayo has mostly struggled at the big-league level, but the former top prospect showed signs of life last September, slashing .301/.393/.548 with five homers.

Gillies will be sidelined for at least six weeks with a quad injury, Roch Kubatko of MASNSports.com reports.

Gillies had been in camp as a non-roster invitee and will now get a late start to the minor-league season. The 6-foot-8 right-hander posted a 2.68 ERA and 51:13 K:BB over 53.2 frames between Double-A Chesapeake and Triple-A Norfolk in 2025.

Sweeney will have his throwing program paused due to a right shoulder strain, Cody Stavenhagen of The Athletic reports.

It's unclear when Sweeney might be ready to throw again, much less play in games. The 25-year-old was already lower down in the pecking order at shortstop for the Tigers, and this setback won't help his chances at earning a spot on the Opening Day roster.

Westburg will be sidelined at least through the end of April due to a partially torn UCL in his right elbow, Matt Weyrich of The Baltimore Sun reports.

Westburg will not undergo surgery and will instead treat the injury with a platelet-rich plasma injection and rest. When he does return, he could do so as a designated hitter initially. Westburg entered Orioles camp with an oblique strain, but that injury should heal long before the elbow issue. While the infielder is shelved, the Orioles could turn to Coby Mayo or Blaze Alexander to cover third base. Alexander is also in the mix for reps at second base in place of the injured Jackson Holliday (hand).
