Overview
- The Giants said José Buttó has a blood clot in his throwing arm after evaluation by Stanford vascular surgeon Dr. Jason Lee. He is undergoing a procedure to remove it.
- He was pulled after a drop in velocity and arm pain during his last outing, then placed on the 15-day injured list the next day with what was first called forearm fatigue.
- Manager Tony Vitello said there is no timetable for a return. He noted Buttó has dealt with circulation issues before.
- San Francisco recalled Blade Tidwell to take his bullpen spot as the pitching staff adjusts in the near term.
- Reporters note some pitching arm clots are linked to thoracic outlet syndrome, though the team has not said that is a factor here.
