The Marlins placed Henriquez (elbow) on the 60-day injured list Thursday.

The transaction frees up a spot on the 40-man roster for Chris Paddack, whose signing was officially announced Thursday. Henriquez underwent a UCL reconstruction surgery with an internal brace procedure on his right elbow in December and will be sidelined for the duration of the 2026 season.

Walker believes he fixed a mechanical issue over the offseason that had affected his command last season, Alex Pavlovic of NBC Sports Bay Area reports.

Walker discovered that he had been over-rotating, which made it difficult to command his slider, in particular. That led to having to throw more sinkers for strikes, and because the hitter was able to guess what was coming, his sinker got hit harder. After finishing with a 1.91 ERA, 0.85 WHIP and 32.1 percent strikeout rate in 2024, Walker regressed to a 4.11 ERA, 1.28 WHIP and 22.6 percent strikeout rate in 2025. The 30-year-old is the favorite to open 2026 as the Giants' closer, and he could have a bounce-back season if his mechanics are in order.

Lewis has been shut down from throwing after he was diagnosed with a moderate subscapularis strain in his right shoulder, the Minneapolis Star Tribune reports.

Lewis is coming off a disappointing season as he had an ugly 7.27 ERA and 87:68 K:BB ratio in 73 innings at Triple-A in 2025. He missed some time last season with a right shoulder injury, but it's not clear if this setback is related. Lewis has had an unusual career path, as he's increasingly incorporated a knuckleball in his arsenal. He'll likely be shut down for at least a few weeks before being evaluated.

Rodon (elbow) has thrown 5-to-6 bullpen sessions and is scheduled to throw another one Saturday, Meredith Marakovits of YES Network reports.

Rodon also revealed that he was given two platelet-rich plasma injections in his surgically repaired left elbow in order to expediate the healing process. The expectation is that Rodon will make a few Grapefruit League starts and be ready for his season debut in late April or early May.

Cardinals president of baseball operations Chaim Bloom said Thursday that Herrera (elbow) remains limited with his throwing and hitting, Derrick Goold of the St. Louis Post-Dispatch reports.

Herrera underwent surgery in November to remove bone spurs from his right elbow, so he's being eased into things in spring training. The elbow rehab will keep Herrera from participating in the World Baseball Classic for his native Panama due to insurance issues, but it is not expected to affect his Opening Day availability. Herrera is attempting to return to catcher in 2026 after the elbow issue limited him to designated hitter duty for the final few months of the 2025 season.

The Phillies released Castellanos on Thursday.

After attempting and failing to unload Castellanos and his $20 million price tag during the offseason, the Phillies will now cut their losses and release him into free agency. The 33-year-old outfielder took another step back last year, as he slashed .250/.294/.400 with 17 homers, 72 RBI and 72 runs scored across 589 regular-season plate appearances. Despite his regression, the two-time All-Star figures to receive plenty of interest in the open market now that teams will be able to bring him in at a much lower price.

The Royals traded Causey to the Athletics on Thursday in exchange for Mitch Spence.

Causey spent time with the Royals' High-A and Double-A affiliates in 2025, posting a 1.72 ERA and 0.90 WHIP in 73.1 innings across the two levels. The 23-year-old righty will likely begin his tenure with the Athletics in Double-A and aim to reach Triple-A Las Vegas at some point this summer.

The Dodgers placed Phillips (elbow) on the 60-day injured list Thursday, Fabian Ardaya of The Athletic reports.

The move frees a spot on the 40-man roster for Enrique Hernandez (elbow). Phillips will be sidelined for at least the first few months of the 2026 campaign after having Tommy John surgery last May.

The Royals placed Marsh (shoulder) on the 60-day injured list Thursday.

Marsh missed all of 2025 due to shoulder problems, and after undergoing surgery in November to address the issue, he's expected to miss the entire 2026 campaign as well. His move to the 60-day IL clears space on the 40-man roster for Mitch Spence, whom the Royals acquired in a trade with the Athletics on Thursday.

Yankees manager Aaron Boone said Thursday that Schlitter will not throw off a mound for a few days due to mid-back inflammation, Gary Phillips of the New York Daily News reports.

The injury is considered minor, and Schlitter will continue to throw on flat ground. At this point, the Yankees seem to be simply exercising caution, though it's possible Schlittler's Grapefruit League debut gets pushed back. The young right-hander is locked into a spot in the Yankees' rotation after holding a 2.96 ERA and 84:31 K:BB over 73 regular-season innings in 2025.
