Los Angeles Angels star Shohei Ohtani will have season-ending knee surgery Friday but is expected to recover in time for 2020 spring training.

The Angels announced Thursday that the surgery will "address a bipartite patella" in Ohtani's left knee.

The operation carries an expected recovery of 8-12 weeks, according to the Angels.

Ohtani, 25, had Tommy John surgery on his pitching elbow last October and did not pitch or play in the field this season.

Serving exclusively as a designated hitter or pinch hitter, Ohtani batted .286 with 18 home runs and 62 RBIs in 106 games this season.
