Stephenson (shoulder) threw a bullpen session Tuesday, Rhett Bollinger of MLB.com reports.

It's the first time throwing off a mound this spring for Stephenson. The righty missed all of 2024 and much of 2025 due to arm trouble and dealt with a nerve issue and thoracic outlet syndrome symptoms this offseason. Stephenson is a poor bet to stay healthy, but when he's on the active roster he'll be in the mix for high-leverage appearances.

Joyce (shoulder) threw a bullpen session Tuesday, Rhett Bollinger of MLB.com reports.

It's the first time the right-hander has thrown from the bump this spring. Joyce is a tad behind other Angels pitchers as he comes back from last May's surgery to repair a torn labrum in his shoulder, but he seems to have a good shot to be ready Opening Day, barring setbacks. The 25-year-old is expected to be in the mix to close games for the Halos, though he could be eased into high-leverage opportunities following what was essentially a lost season.

Lopez (elbow) completed a bullpen session Monday, Martin Gallegos of MLB.com reports.

Lopez missed the final month and change of the 2025 season due to a left elbow flexor strain, but he appears to have had a normal offseason and doesn't seem to be facing any restrictions in the early stages of camp. The 27-year-old lefty should be guaranteed a rotation spot heading into 2026 after he was one of the few bright spots for a wretched Athletics pitching staff last season with a 4.08 ERA, 1.27 WHIP and 19.0 K-BB% over 92.2 innings.

Hernandez is making progress but is still in the midst of a rehab program after suffering fractures to his left arm and right leg during a Jan. 11 car accident in Venezuela, SI.com reports.

Hernandez is still sporting a cast on his injured arm and is walking with the assistance of a crutch just over a month after the accident, so he doesn't appear likely to take part in spring training workouts anytime soon. The 28-year-old right-hander signed a minor-league deal with Cleveland in November and is expected to settle into the bullpen at Triple-A Columbus once he fully recovers from his injuries. Hernandez pitched primarily in the majors in 2025, logging a collective 6.23 ERA and 1.66 over 43.1 innings across stops with the Phillies, Tigers and Guardians.

The Mariners placed Evans (elbow) on the 60-day injured list Monday.

The transaction clears a spot on the 40-man roster for the arrival of Josh Simpson, who was acquired via trade with the Marlins on Monday. Evans will miss the entire 2026 season after undergoing UCL reconstruction surgery with an internal brace in January.

The Mariners acquired Simpson from the Marlins on Monday in exchange for cash considerations.

Simpson reached the big leagues for the first time in 2025 but was unable to work his way into a high-leverage role with Miami after submitting a 7.34 ERA and 1.83 WHIP in 30.2 innings. The southpaw yielded five home runs over 31 appearances and walked 14.6 percent of the batters he faced, but he generated ground balls at a high rate (59.6 percent) and struck out hitters at a decent clip (23.8 percent). Seattle recognized enough potential in Simpson to bring him aboard as an extra left-handed option out of the bullpen and opened up a 40-man roster spot for him by placing Logan Evans (elbow) on the 60-day injured list.

Watson is scheduled to begin a throwing program Monday as he works his way back from arthroscopic right elbow surgery, Evan Petzold of the Detroit Free Press reports.

Watson is in camp as a non-roster invitee, but he may not have enough time to complete his rehab and see Grapefruit League action before the end of the spring. Whenever he's back to full health, He's likely to head to Triple-A Toledo, where he'll presumably settle back into a starting role. After beginning last season as a reliever, Watson held his own upon moving into the Toledo rotation, logging a 3.20 ERA while punching out 59 batters over 70.1 innings across 14 starts.

The Tigers announced Sunday that Darnell (hip) has been playing catch five times a week and is also taking part in a running progression, Evan Petzold of the Detroit Free Press reports.

Darnell has opened camp behind the team's healthy bullpen candidates after undergoing left hip labral repair surgery in September. The 28-year-old could be ready to get back onto a mound soon, but he still looks like he'll face an uphill battle to win a spot on the Opening Day roster.

Sborz (shoulder) tossed a bullpen session Saturday, Jeff Wilson of AllDLLS.com reports.

The 32-year-old righty looks to be healthy for the start of spring training after he was limited to just a handful of minor-league rehab appearances in 2025 after undergoing surgery on his throwing shoulder in November 2024. After the Rangers non-tendered him in November, Sborz re-signed with the organization on a minor-league deal in January. He'll need to regain his pre-surgery velocity and command in order to make a serious run at a spot in the Opening Day bullpen.

Rays manager Kevin Cash said Sunday that Uceta arrived at camp with a "cranky shoulder" and won't be available to pitch for the Dominican Republic in the World Baseball Classic as a result, Marc Topkin of the Tampa Bay Times reports.

Cash labeled the decision to pull Uceta out of the WBC as precautionary and indicated that the Rays fully expect the right-hander to be ready to go for Opening Day. The team heads into the upcoming season without a set closer after letting Pete Fairbanks walk in free agency, and Uceta could factor into the team's late-inning mix if his shoulder isn't a concern. The 28-year-old netted one save and 21 holds over 70 appearances last season while racking up an impressive 103 strikeouts across 76 frames.
