Overview
- Manager Mark Kotsay announced Wednesday that two-time All-Star Brent Rooker will undergo season-ending surgery to repair a cartilage tear in his left knee.
- The tear was found during a Stanford Medical Center reevaluation after Rooker paused rehab for a left knee bone bruise and conservative treatment failed.
- Rooker has not played since June 8 and was batting .200 with 10 home runs and 29 RBIs in 48 games before he was placed on the injured list.
- Oakland faces a roster squeeze with a season-high nine players on the injured list, and the club plans to cycle Joey Meneses, Colby Thomas, Max Muncy, Jonah Heim and Shea Langeliers through the DH spot.
- Rooker was a durable power hitter from 2023–25 (99 home runs across those seasons and a full 162-game season in 2025), the team has not set a surgery date, and no timetable for his return has been announced.
