Armstrong was recently cleared to begin a throwing progression, a good indication that he is recovering from a left calf strain that landed him on the injured list in late July. He was transferred to the 60-day IL on Aug. 4, but he could be back on the Guardians' major-league roster right before the end of the regular season in mid-to-late September.

Armstrong hit the 15-day injured list July 25 due to left calf strain. He won't be eligible to return until Sept. 23, so there's a chance he will not return until the 2027 season.
