Seattle Mariners

Matt Brash

RP

Brash resumed throwing off the mound earlier this week and is now ready to test things out in a game setting. The setup reliever has been out for all of May with right lat inflammation but appears close to a return if he can avoid a setback.

Cal Raleigh

C

Raleigh tweaked his oblique Wednesday in Houston and has landed on the IL for the first time in his career. Oblique strains typically result in longer than minimum absences, but more will be known about Raleigh's timetable once the Mariners return to Seattle and he's examined further. Mitch Garver and Jhonny Pereda will share catching duties for Seattle while Raleigh is out.

Miles Mastrobuoni

3B

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.

Teddy McGraw

SP

McGraw's inability to stay healthy has defined his pro career thus far. Selected in the third round of the 2023 draft, McGraw has thrown just 37 innings in pro ball due to consistent elbow injuries -- he had Tommy John surgery in 2019 and internal brace in 2023.

Patrick Wisdom

1B

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.
