The Texas Rangers activated Dane Dunning from the 15-day injured list Thursday and optioned fellow right-hander Gerson Garabito to Triple-A Round Rock.
Dunning was placed on the injured list on July 5 (retroactive to July 4) with right shoulder soreness.
He allowed one hit and struck out three batters over five scoreless innings in a total of two rehab assignments (one start) with Double-A Frisco and Round Rock.
Dunning, 29, is 4-7 with a 4.71 ERA in 15 appearances (12 starts) with the Texas this season. Dunning also missed time in May with shoulder discomfort.
