Pirates' Joe Musgrove: Will begin rehab assignment Tuesday

Musgrove (shoulder) will join High-A Bradenton for a rehab assignment Tuesday, Adam Berry of MLB.com reports.

Musgrove has yet to make his Pirates debut while battling a shoulder injury. He'll start out by throwing just three innings and is expected to make four starts while ramping up to a full starter's workload. Assuming each start comes on four days' rest, he'd be lined up to start for the Pirates in their series with the Reds that runs May 22 to 24.
