Sidelined the entire 2011 season with an elbow injury, Zumaya's comeback this spring was quickly halted in late February when he tore the ulnar collateral ligament in the same elbow during a live batting practice session.
The 27-year-old right-hander signed a one-year, $850K contract with the Twins in January, but is set to only make $400K because he did not make the opening day roster.
Zumaya's entire career has been plagued by a variety of arm injuries. The flame-throwing right-hander has only thrown over 35 innings in a season once in his five-year career because of shoulder, wrist, finger and elbow ailments.
Zumaya will undergo Tommy John surgery later this week and will be out for at least a year.
