Seattle Mariners

Brendan Donovan

2B

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.

Miles Mastrobuoni

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.

Patrick Wisdom

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.

Bryce Miller

SP

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.

Victor Robles

RF

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.
