Alzolay (lat) started a rehab assignment Monday with the Cubs' rookie-level Arizona Complex League affiliate, Meghan Montemurro of the Chicago Tribune reports.
Alzolay opened the 2022 campaign on the injured list due to a strained right lat, but he's been ramping up his activity of late. He'll likely need to prove his health in at least a few rehab outings before having a chance to be activated from the 60-day IL before the season ends.
