ANAHEIM -- Angels closer Huston Street underwent season-ending surgery on his right knee on Wednesday, the Angels announced.
Street had arthroscopic surgery for "persistent medial knee pain," according to the Angels. The surgery was performed by Dr. Keith Meister in Austin, Texas.
Street, 33, has been sidelined by the knee issue since Aug. 2. He's been limited to 26 appearances this season, going 3-2 with nine saves and a 6.45 ERA, a 1.93 WHIP and a 1.17 strikeout-to-walk ratio. He also missed 32 games in April and May because of a strained left oblique muscle.
Street is set to earn $9 million next season and has a $10 million club option for 2018 ($1 million buyout).

The Angels have used Fernando Salas in the closer's role in Street's absence.
