Winder (shoulder) is continuing his rehab assignment at Triple-A St. Paul, Brandon Warne of Access Twins reported Tuesday.
Winder's rehab stint began with Low-A Fort Myers on April 30, and despite allowing four runs in 3.2 innings, he'll move up to St. Paul to continue his recovery. Even though he's set to return in late May or early June, Winder isn't guaranteed a big-league roster spot, so he'll likely need to make a strong case during his time at Triple-A to improve his chances.
