Overview
- The Mariners paused Brash’s throwing program after he felt right-lat tightness following a recent bullpen and doctors ordered an MRI to evaluate the area.
- Reporting from The Seattle Times and MLB Trade Rumors says the MRI showed increased inflammation but no structural damage, and the club has halted his throwing for about eight weeks.
- Brash has been on the injured list since June 9 with a recurring right-lat strain and this marks his second IL stint this season after an earlier May absence for the same issue.
- General manager Justin Hollander described a pattern where Brash feels fine on flat-ground work and during pens but develops tightness afterward, which has blocked progression to live batting practice and rehab starts.
- The shutdown removes a high-leverage arm from a bullpen that has struggled since August and compounds roster pressure while other pitchers such as Nick Davila and Brendan Donovan also face season-ending or recovery setbacks.
