San Francisco Giants relief pitcher José Butto underwent arm surgery on Friday that is expected to sideline him for 5-6 months, the team announced on Saturday. Butto is a key member of the Giants' bullpen who has been a reliable setup man for the past two seasons.

The right-hander has been a valuable contributor out of the bullpen, and his injury creates a void that the team will need to fill through trades, free agent signings, or by promoting from within their minor league system.

Butto underwent the surgery on his throwing arm on Friday, though the team did not provide specifics on the nature of the procedure. The 28-year-old reliever is expected to be sidelined for 5-6 months as he recovers and rehabilitates the injury.
