The comeback bid of two-time Cy Young Award winner Johan Santana has ended because of a torn Achilles tendon.
The injury occurred Friday while the left-hander was pitching for the Baltimore Orioles in extended spring training. Santana was struck by a line drive, then stumbled when chasing the ball.
Orioles vice president of baseball operations Dan Duquette says an examination determined a tendon tear.
Duquette said of Santana: "He won't be able to pitch for the Orioles this season."
The 35-year-old Santana has not pitched in the majors since 2012 with the New York Mets. He signed a minor league contract with Baltimore in March.
Santana's return appeared on course when the Orioles purchased his contract from Triple-A Norfolk on Monday and placed him on the major league disabled list.
