The injury won't cost the 21-year-old another elbow surgery, but orthopedic specialist Dr. James Andrews recommended that the Tigers rest Crosby to quiet the swelling and give him a better chance of coming into next spring healthy.
Crosby opened the season on the disabled list with elbow tenderness and had a slow recovery before being cleared for a rehab assignment in the Gulf Coast League. He gave up 15 runs, 12 earned, on 21 hits over 12 1/3 innings in three starts there, including nine runs over 3 1/3 innings in his final start on July 3. That was supposed to be a five-inning, 75-pitch performance.
The Tigers sent him back to Dr. Andrews after that for exams.
"Structurally, he's fine," Tigers head athletic trainer Kevin Rand said Monday. "Dr. Andrews recommended we shut him down from throwing for six to eight weeks."
Crosby's velocity was strong, Rand said, but he had residual swelling.
The move continues what has been a rough summer for Tigers pitching prospects. Former first-round Draft pick Jacob Turner, regarded alongside Crosby by many as Detroit's top prospect, pitched relatively well at Class A West Michigan, but has had growing pains in four starts at high Class A Lakeland. Relief prospect Cody Satterwhite is out for the season following shoulder surgery, and Robbie Weinhardt also missed time before his promotion to Detroit earlier this month. Andrew Oliver has arguably been the brightest spot in the system armwise.
