Yeah, probably not a good sign for him returning any time soon . . . bummer.
From Rotowire 6/22/22: "Alcala (elbow) will resume his throwing program next week, the Minneapolis Star Tribune reports. Alcala has been on the injured list since April 12 with right elbow inflammation. He made a rehab appearance June 1 but was later shut down again with tightness in his pitching elbow. He's still likely a long way away from returning, but at least he's showing some progress and his setback wasn't season ending."
