Seattle transferred Mastrobuoni (calf) from the 10-day injured list to the 60-day IL on Monday.

Mastrobuoni had been in the midst of a rehab assignment with Triple-A Tacoma and appeared to be on the cusp of a return from the 10-day IL, but his move to the 60-day IL likely indicates that he suffered some sort of setback over the weekend. As a result of the transaction, Mastrobuoni now won't be eligible to make his 2026 debut with the Mariners until the final week of May, though an exact timeline for his activation is unclear. The utility player initially suffered the right calf strain in March while playing for Team Italy in the World Baseball Classic.

Mayo is out of the lineup for Monday's game against the Royals, Matt Weyrich of The Baltimore Sun reports.

Mayo started each of the Orioles' previous five games but was unable to wake up from his season-long slumber at the plate, going just 2-for-16 with a double and a 2:5 BB:K. Now holding down a .148/.258/.185 slash line for the season, Mayo looks like he'll be part of a timeshare at third base with Blaze Alexander, who receives the starting nod Monday. The 24-year-old could be at risk of a demotion to Triple-A Norfolk once Jackson Holliday (wrist) is back from the injured list, as Holliday's return would likely result in the hot-hitting Jeremiah Jackson moving off second base and cutting further into Mayo's playing time at the hot corner.

Rays manager Kevin Cash said Monday that Uceta will be shut down for 2-to-3 weeks after being diagnosed with a right shoulder strain, Marc Topkin of the Tampa Bay Times reports.

Uceta began the season on the injured list with a right shoulder impingement, and he suffered a new shoulder injury during his last rehab appearance with Triple-A Durham on Wednesday. The righty reliever will need time to get built back up once he does resume throwing, so Uceta will be out for several more weeks even in a best-case scenario. He's a candidate to be moved to the 60-day IL when/if the Rays need to free up a spot on their 40-man roster.

Rays manager Kevin Cash said that Pepiot's injured right hip felt "unstable" while the pitcher played catch Monday, Marc Topkin of the Tampa Bay Times reports.

Pepiot suffered a setback with his right hip last week when he threw a bullpen session, which resulted in him being shifted to the 60-day injured list. He was given an injection and shut down for a few days, and it seems the hip issue is still lingering. It's unclear whether Pepiot will be shut down again, but clearly the righty isn't progressing as well as hoped. He won't be eligible to make his season debut with the Rays until May 24.

The Athletics recalled Basso from Triple-A Las Vegas on Monday.

Basso will provide a fresh relief arm after the Athletics' bullpen was overworked in recent days. The left-hander has permitted seven runs with an 8:3 K:BB over 6.2 innings with Las Vegas in the early going this season.

The Athletics optioned Barnett to Triple-A Las Vegas on Monday.

Barnett needed 43 pitches to cover two-plus innings Sunday versus the White Sox in his lone appearance in the majors. Since Barnett would have been unavailable to pitch for a day or two, the Athletics have summoned a fresh bullpen arm to take his roster spot.

Bohorquez was placed on 7-day injured list at High-A Cedar Rapids with a right forearm strain, Theodore Tollefson of Zone Coverage reports.

Given the nature of the injury, it could be a lengthy absence for the 21-year-old hurler. Bohorquez carries an 11.25 ERA and 13:9 K:BB over eight innings in his first three starts with Cedar Rapids this season.

Trammell will start in center field and bat sixth in Monday's game against the Guardians.

Trammell will draw his fifth consecutive start and should have a clear path to an everyday role in center field for the time being after Joey Loperfido (quadriceps) recently joined Jake Meyers (oblique) on the injured list. Since receiving a call-up from Triple-A Sugar Land on April 10, Trammell has slashed .321/.387/.429 with two extra-base hits (one double, one triple), one stolen base, four RBI and four runs in nine games.

Smith is out of the lineup for Monday's game against the Guardians, Matt Kawahara of the Houston Chronicle reports.

Smith will exit the starting nine for just the second time through the Astros' first 24 games, clearing the way for waiver pickup Dustin Harris to make his first start with Houston. Though he'll head to the bench after going hitless in each of his last four games, Smith is still holding maintaining a .764 OPS on the season, well ahead of the .670 mark that he posted during his 2025 rookie campaign.

Lambert is slated to start Wednesday's game against the Guardians in Cleveland, Matt Kawahara of the Houston Chronicle reports.

Summoned from Triple-A Sugar Land last week after submitting a 1.84 ERA and 0.95 WHIP over his first three starts in the minors, Lambert stepped in to fill one of the opening in Houston's injury plagued rotation. Though he was dealt a loss Friday against the Cardinals after yielding four runs and allowing 10 baserunners in five innings, Lambert posted a strong 8:1 K:BB and racked up 23 swinging strikes on 90 pitches. That massive whiff total alone makes Lambert a worthwhile speculative pickup in deeper leagues, and another quality showing against the Guardians could allow the 29-year-old righty to solidify a more permanent spot in a rotation that isn't expected to get any of its injured starters back anytime soon.
