The Guardians activated Cecconi (arm) from the 15-day injured list Friday, Tim Stebbins of MLB.com reports.
Cecconi has been sidelined for nearly a month with right arm fatigue, but he's been cleared to return after allowing two runs over 3.2 innings in two rehab outings. The right-hander will be used in a relief role down the stretch, and there's a good chance he'll be needed to pitch during Friday's doubleheader against the Tigers.
