Reyes was diagnosed with a frayed labrum in his right shoulder Friday and is expected to be sidelined until at least late May, Jeff Jones of the Belleville News-Democrat reports.
Reyes will be shut down from throwing for at least the next two weeks after receiving an injection of stem cells, and he's set to work out at the Cardinals' extending spring training once cleared to start his throwing program. The 27-year-old was expected to be a piece of St. Louis' closer committee to open 2022, but he'll instead start out on the injured list. Giovanny Gallegos and Genesis Cabrera should split save opportunities in his absence.
