PHOENIX -- Right-hander Hiram Burgos, part of the Brewers' Minor League pitching depth, underwent right shoulder surgery on Thursday that could sideline him the rest of the season.
Brewers manager Ron Roenicke said the club's athletic training staff characterized the procedure as a "clean-up." Burgos, 26, also was bothered by a shoulder problem last season, when he excelled in the World Baseball Classic for Puerto Rico before making his Major League debut early in the season, but did not pitch in the Majors or Minors after July 7.
Burgos was able to regain strength in his shoulder without surgery, but he felt renewed discomfort this year after four starts for Triple-A Nashville.
"I don't think there's anything major, they just want to go in and make sure," Roenicke said after consulting with the medical staff. "He was going, but it just didn't seem right to him."
