The Pittsburgh Pirates have placed ace Gerrit Cole on the 15-day disabled list with right elbow inflammation.
Cole pitched five shaky innings in a 5-4 loss to Houston on Wednesday, and then let the team know he experienced some discomfort during the outing. He had a 6.08 ERA in five August starts.
Left-hander Steven Brault was promoted from Triple-A Indianapolis to take Cole's spot in the rotation Monday night at the Chicago Cubs.
Cole's injury means none of Pittsburgh's five starters from opening day are currently in the rotation. Francisco Liriano and Jon Niese left via trade and Jeff Locke and Juan Nicasio are working out of the bullpen.
Manager Clint Hurdle said Monday the decision to have Jung Ho Kang continue his injury rehab in Indianapolis instead of Chicago has nothing to do with an investigation into the infielder for an allegation of sexual assault.
Kang traveled with the team to Milwaukee, but went to Triple-A Indianapolis to work out when the team traveled to Chicago for a three-game series against the Cubs. Hurdle said the lack of facilities at Wrigley Field and the team's workout schedule were the main reasons for the move.
Kang hurt his left shoulder sliding head first into second base in the eighth inning of a 6-5 loss to Miami on Aug. 19. He is expected to miss two to four weeks.
Hurdle said Kang took batting practice and fielded grounders while the team was in Milwaukee.
