Ruiz (wrist) underwent right knee arthroscopic surgery Tuesday, Martin Gallegos of MLB.com reports.
A patella tendon debridement and a chondroplasty procedure were performed on the knee. Ruiz -- who had already been ruled out for the season with a left wrist strain -- will rehab this offseason in hopes of being ready in time for spring training. The 25-year-old played 29 games for the Athletics this season, producing a .652 OPS with two homers and five steals.
The Athletics transferred Ruiz (wrist) to the 60-day injured list Wednesday.
Ruiz has already been ruled out for the remainder of the season after suffering a left wrist strain in May, so the A's will give his spot on the 40-man roster to CJ Alexander, who was claimed off waivers from Kansas City on Wednesday.
Manager Mark Kotsay said Saturday that Ruiz (wrist) will not return from the 10-day injured list this season, Martin Gallegos of MLB.com reports.
Ruiz has been on the IL since late May due to a left wrist strain, and a setback forced him off his rehab assignment July 20. After going more than a month without playing and making little progress in his recovery, the speedy outfielder won't attempt to ramp back up for a return before the season ends in late September. He'll close the book on 2024 with a .200/.270/.382 slash line along with five stolen bases over 29 games.
