June 13, 2025 5:24 PM : Slaten (shoulder) hasn't started playing catch yet, Christopher Smith of MassLive.com reported Friday
Analysis: Slaten has been shut down from throwing for nearly two weeks, having not played catch since hitting the injured list June 1 with right shoulder inflammation. It's unclear when he'll get the green light to throw, but he may not be ready to go until July.
