Detroit Tigers right-hander Jeremy Bonderman had surgery Monday to correct a condition that caused a blood clot in his pitching arm.
Bonderman was placed on the disabled list the first week in June after having the blood clot broken up and getting an angioplasty.
Dr. Greg Pearl performed a procedure in Dallas to correct thoracic outlet compression syndrome, a condition that pinches the vein responsible for returning blood from the arm to the heart and caused the clot.
The team has not put a timetable on Bonderman's return to the mound.
Kenny Rogers underwent a similar procedure for the same condition that kept him out for most of the 2007 season, but he has returned to pitch for Detroit this year.
