Peralta (illness) threw a bullpen session at the Yankees' Double-A stadium in Somerset on Saturday, Mike Ashmore of PatriotsBaseball.com reports.
Peralta was one of several Yankees to test positive for COVID-19 in mid-July, and he is just beginning to work his way back into game shape. According to Julio Mosquera, manager of the Double-A Somerset Patriots, Peralta is "trying to get his feet back under him and make sure body responds the right way." The lefty reliever could go on a minor-league rehab assignment prior to being activated, Bryan Hoch of MLB.com reports.
