Flaherty (shoulder) played catch on flat ground ahead of Friday's game at Milwaukee, Jeff Jones of the Belleville News-Democrat reports.

EDGE Analysis

Flaherty has been building up his arm and shoulder strength with plyometric exercises, and he's now been cleared to start a throwing program. The 26-year-old was shut down from throwing in mid-March after receiving a PRP injection to address inflammation in his right shoulder, so he'll likely require a significant buildup period before progressing to mound work.
