The Athletics transferred Rooker (knee) to the 60-day injured list Friday.
Rooker has already been ruled out for the remainder of the 2026 season, and he recently underwent surgery to repair torn cartilage. He's expected to be ready for the start of spring training in February. When healthy this season, Rooker slashed a disappointing .200/.281/.389 with 10 homers, 29 RBI, 20 runs scored, two stolen bases and a 19:65 BB:K across 203 trips to the plate.
