Core Event
Designated hitter and outfielder Brent Rooker underwent arthroscopic surgery on his left knee on Friday, a procedure that ends his participation for the remainder of the 2026 MLB season. The surgery, performed by Dr. Tim McAdams and Dr. Mike Freehill at Stanford Orthopedic Hospital in Redwood City, repaired an articular cartilage tear and removed loose bodies. The Athletics transferred Rooker to the 60-day injured list and announced the move alongside several other roster adjustments.
Background & Player Profile
Rooker, a two-time All-Star, entered the 2026 season on a five-year, $60 million contract signed in January 2025. After playing all 162 games in 2025, he struggled with injuries this year, missing 15 games in April with a strained right oblique and receiving a cortisone shot for his knee in May. In 48 games this season, he posted a .200 batting average with 10 home runs and 29 RBIs. Over his four-year tenure with Oakland, he has compiled a .261/.337/.498 slash line, 299 RBIs and 109 home runs in 492 games.
Official Team Statement & Roster Moves
The Athletics confirmed that Rooker’s recovery is expected to be complete in time for the start of 2027 spring training. In addition to moving Rooker to the 60-day IL, the club designated starting pitcher Aaron Civale for assignment and promoted infielder Tommy White from Triple-A Las Vegas. Management emphasized that the team will “do our best to fill that void and make the best of the situation.”
Impact on the Athletics’ Season
Rooker’s departure removes a “middle-of-the-order bat” that has produced 30-plus home runs in each of the past three seasons. The Athletics have lost 13 of their last 14 games, and the loss of his leadership and power hitting deepens concerns about the team’s offensive production as it heads into the second half of the season.
Verbatim Quote
“This is a big blow,” Athletics manager Mark Kotsay told reporters on July 1. “It’s a middle-of-the-order bat; it’s a guy that has produced for us the last three seasons, 30-plus homers. In terms of replacing Rook, there’s not one guy that’s going to come in here and step in and do that type of production, but we’ll do our best to fill the void and make the best of the situation.” — Mark Kotsay, Athletics Manager
