ANAHEIM, Calif. — Shohei Ohtani has a right forearm strain that will prevent the Los Angeles Angels’ two-way star from throwing for at least four to six weeks, possibly ending his season as a pitcher after just two starts.

Angels general manager Billy Eppler announced Monday that Ohtani “has a grade 1-2 strain of the flexor pronator mass” — a collection of muscles and tendons in the forearm near the elbow.
