An MRI was performed on right-hander Edinson Volquez’s left knee on Friday, casting doubt on his scheduled return to the rotation on Sunday. Volquez is continuing to experience discomfort in the knee, according to manager Don Mattingly.
“I’m not as optimistic as I was before I left for the [All-Star] break,” Mattingly said.
Volquez was placed on the 10-day disabled list following his start in St. Louis on July 5, when he came out after four innings because of soreness in his landing knee.
“He went back to the Dominican [Republic], and I know he threw over the break,” Mattingly said.
