Crochet (lat/shoulder) was spotted playing catch off the mound Monday, Mac Cerullo of the Boston Herald reports.
Crochet has taken the latest step forward in his throwing progression as he works his way back from left shoulder and lat discomfort, which has kept him out of commission since late April. The southpaw won't have enough time to rebuild his stamina to return as a starting pitcher, but the Red Sox are optimistic that he can contribute as a reliever at some point in September.
