Shohei Ohtani of the Major League Baseball team, the Los Angeles Angels, has begun rehabilitation three days after undergoing knee surgery.
Ohtani had the operation in Los Angeles on Friday. He had experienced pain in his left knee this season.
The Angels had said that the Japanese star would take some time to rest, but sources say Ohtani began rehabilitation at his home field in Anaheim on Monday.
Ohtani reportedly performed upper body training with the team's medical staff in presence. He is also said to have had a lower body massage to help his circulation and speed up his recovery.
Ohtani is set to practice throwing the ball while in a seated position for about three weeks. He will then play catch and aims to resume full-fledged pitching training about 10 weeks after his surgery.
Ohtani had surgery on his right elbow last year and had focused on batting this season. The Angels hope to have Ohtani as a two-way player next season as it had originally intended.
