Guardians activated RHP Shawn Armstrong from the 60-day injured list.

Armstrong returns to Cleveland’s bullpen mix after missing two months with a left calf strain. The 36-year-old veteran reliever is back for Wednesday’s contest against the Red Sox. He’s compiled a serviceable 4.91 ERA, 1.45 WHIP and 33/19 K/BB ratio across 33 innings this season.
