MINNEAPOLIS -- Right-hander Mike Pelfrey felt shoulder soreness after his rehab start with Triple-A Rochester on Friday and flew to Minnesota to have it checked out by team doctors on Wednesday.
Pelfrey was originally placed on the 15-day disabled list with a groin strain on May 2 and made two rehab starts with Rochester. His groin is no longer bothering him but he felt shoulder discomfort a few days after Friday's start, so the Twins removed him from his rehab assignment on Wednesday. He'll start another rehab assignment once he's cleared to pitch again.
But there's no timetable for his return to the mound. Pelfrey still needs to meet with team doctors to find out what's wrong his shoulder.
"He has to get that checked out and see what's going on there," Twins assistant general manager Rob Antony said. "He came to the ballpark yesterday and reported he had some soreness and stiffness in his shoulder."
