Overview
- The Astros said Tuesday that Brown has a Grade 2 right shoulder strain and will stop throwing for a few weeks, with a reevaluation planned in about two weeks.
- Manager Joe Espada and GM Dana Brown said the issue is muscular with no structural damage, and the team has not set a return date.
- Houston will shift to a six-man rotation after Thursday’s off day, with Triple-A right-hander Spencer Arrighetti expected to cover a turn.
- Medical reporting on Grade 2 shoulder strains points to about six weeks to resume light throwing and closer to 8–10 weeks for a starter to ramp back to game duty.
- Brown opened 2026 with a 0.84 ERA and 17 strikeouts in 10.2 innings, and his absence adds strain to a staff already missing Josh Hader, Ronel Blanco, and Nate Pearson with a shaky bullpen.
