The issue is with one of Garcia’s knees.
“He’s still in rehab,” Roberts said. “I don’t know the next time he’s going to pitch.”
Garcia pitched on back-to-back days Thursday and Friday for the first time since joining the Double-A Tulsa roster this week. He allowed three runs in one-third of an inning Thursday and one run in one inning Friday.
The 25-year-old right-hander was placed on the 60-day disabled list April 23.
