Mariners vs White Sox

Donovan landed on the 10-day injured list Monday after missing Seattle's previous two matchup due to the left groin injury. "It doesn't seem like it's going to be a longer-term situation," said manager Dan Wilson. "But again, we just kind of have to assess it as we go." Wilson also mentioned that Donovan's groin injury seems to be related to a sports hernia, which required surgery last October and forced him to miss the last month of the 2025 while with St. Louis. "This is just something that we're going to take as cautiously as we can. It's early and we want to give him the best chance to get back and be 100%," noted Wilson. An official timetable for Donovan's return should come into focus after he starts to make progress in his rehab.

General manager Justin Hollander said Miller will likely need the full 30 days to build his arm up, according to Kramer. The plan for Saturday is for Miller to throw two innings or 30 pitches. The right-hander missed almost the entirety of spring training and has been throwing for the last couple weeks. It sounds like he could rejoin the Mariners later next month.

The transaction will clear a spot on the 40-man roster for the addition of Connor Joe. Vargas has been out all season while recuperating from a right lat strain and now is not eligible to return until late May. It's not clear whether Vargas has resumed throwing or remains shut down.

Evans missed several weeks during the second half of last season with right elbow inflammation, so it's possible he had UCL damage for a while that was only recently discovered. He will miss the entire 2026 season and, given the timing of the procedure, could get a late start to the 2027 campaign, as well. Evans had been likely to open the upcoming season at Triple-A Tacoma, but his absence is a blow to the Mariners' pitching depth. The 24-year-old posted a 4.32 ERA and 59:31 K:BB over 81.1 innings covering 15 starts and one relief outing last season.

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.

Wisdom may have picked up the injury during his last outing Tuesday against the Padres, when he struck out in his lone plate appearance. Wisdom is eligible to be activated from the IL in late April, though oblique injuries tend to take more time to recover from. Rob Refsnyder (personal) was activated from the Mariners' paternity list in a corresponding move.

The 28-year-old landed on the shelf last week due to a right pectoral strain, and the Mariners are building him back up slowly since it's an injury to his throwing arm. Robles will be eligible to be reinstated Friday but seems likely to require a longer stint on the IL.

Hays has been cleared to take the next step in his recovery from a Grade 1 right hamstring strain that caused him to land on the 10-day injured list April 7. He'll head to Triple-A to get some in-game reps and is inching closer to returning to the majors, barring a setback.

Baldwin was hurt during spring training and eventually diagnosed with a sprained UCL. The utility player elected to have surgery rather than rest and rehab, which has ended his 2026 campaign before it starts. Baldwin is expected to be ready for the start of spring training next year.

Murphy gave up seven runs over his first six innings out of the White Sox' bullpen this season before going down with a left elbow impingement. He has been sidelined only for just over two weeks, so Murphy's rehab assignment shouldn't take long if all goes well.

Cannon went to the injured list April 14, but a clear timeline for his return was never established. That remains the case, as there has been nothing reported about his response to the bullpen session or when he will throw again. However, because a rehab assignment will be required, Cannon will be sidelined at least into early May.

Teel had been scheduled to kick off a rehab assignment with Triple-A Charlotte on Monday, but that's been pushed back. The catcher noted that his hamstring strain -- which he initially suffered in mid-March while playing for Team Italy during the World Baseball Classic -- is "getting better every day," but it just isn't progressing as quickly as hoped. Edgar Quero and Reese McGuire will continue handling catching duties for the White Sox until Teel is ready.

The move clears a spot on the 40-man roster for the addition of Dustin Harris. Vasil underwent Tommy John surgery in March and will be sidelined until around midseason next year.

Fletcher saw action in 12 games in the majors with the White Sox in 2025, but after joining the Pirates on a minor-league pact over the winter, he was viewed as a longshot to break camp with the big club. He'll likely be in line for steady at-bats at Indianapolis but will presumably need an injury or two to hit the Pittsburgh outfield before he gets another chance in the big leagues.

Clevinger will be immobilized for several weeks before resuming workouts. The veteran right-hander has been pitching out of the bullpen at Triple-A Indianapolis, allowing five runs with a 9:5 K:BB across 8.2 innings. He won't be an option for the Pirates until sometime in June, at the earliest.
