José Buttó

San Francisco Giants relief pitcher Jose Butto (right arm fatigue) was diagnosed with a blood clot in his right arm after exiting Wednesday's game with discomfort, according to Alex Pavlovic of NBC Sports. He has been placed on the 15-day injured list, and he underwent a procedure to remove the blood clot on Friday. The 28-year-old right-hander has allowed five earned runs over two innings (three appearances) this season. He has surrendered two homers and four walks while striking out five batters. It's been an uncharacteristically poor start to the year for Butto, who was projected to be a setup candidate in the Giants' bullpen after posting a 3.70 FIP last season. He'll be eligible to return from the injured list as early as April 17.
