San Francisco Giants pitcher Jose Butto is set to have surgery to remove a blood clot discovered in his throwing arm, following his placement on the injured list Thursday due to arm fatigue.
The right-handed reliever had been dealing with discomfort in his arm prior to making three appearances out of the bullpen this season, posting a difficult 22.50 ERA across just two innings of work. Throughout his five-year major league career split between the New York Mets and Giants, Butto holds a record of 13-10 with four saves and a 3.76 ERA.
The Giants moved Butto to the 15-day injured list earlier this week and brought up right-hander Blade Tidwell from their Triple-A affiliate in Sacramento. Tidwell made an impressive debut Thursday night, throwing three shutout innings in relief against the New York Mets to earn his first major league save.
Both Tidwell and Butto joined the Giants organization last July as part of a trade package that also included outfielder Drew Gilbert, with all three players coming from the Mets in exchange for right-handed pitcher Tyler Rogers.
