Matt Brash

Placed on the 15-day IL with a lat strain, retroactive to June 9. Brash has been a key high-leverage arm for Seattle in 2026. His absence further thins the Mariners' bullpen behind Andrés Muñoz, who is already dealing with command issues and five blown saves on the year. The lat strain timeline is typically 3-6 weeks.

ACTIVATED: Mariners activated Brash from the 15-day IL Tuesday. He's been out since March with a hamstring issue. His pre-injury upside (top-10 RP material in 2024) is intact; he'll work setup behind Andrés Muñoz initially but is the next-up if Muñoz slips. Hold in deep leagues; speculative add.

NEW: 15-day IL retroactive to April 30 with right lat inflammation. A setback for Brash, who had been working back into a high-leverage role behind Andrés Muñoz. Josh Simpson recalled to take the roster spot.
