New York Mets pitcher Dillon Gee has undergone surgery to remove a blood clot from an artery in his throwing shoulder.
The team said Tuesday no timetable has been set for the right-hander's return, but he will miss his next start and likely will be put on the disabled list.
Gee complained of numb fingers on his right hand Sunday, a day after he pitched. Tests on Monday revealed the shoulder clot.
Doctors used a catheter to break up the clot. The 26-year-old pitcher will remain hospitalized for a day or two to make sure the problem is fully resolved.
Gee pitched eight innings of one-run ball in Saturday's 3-1 win over the Chicago Cubs. He was scheduled to start New York's first game after the All-Star break against the Braves.
He is 6-7 on the season with a 4.10 ERA and has been one of the Mets' most effective pitchers recently, with a 3.34 ERA over the last month.
