The Texas Rangers activated right-hander Darren O'Day from the 60-day disabled list prior to Saturday night's game against the Florida Marlins.
O'Day had been out since April 27 with a partial tear of the labrum in his left hip. He compiled a 2.45 ERA in eight relief appearances for Texas before the injury.
After recovering from surgery on the hip, O'Day had a 3.68 ERA in six minor league relief appearances leading to his return to the Rangers' roster.
To create a spot for O'Day on the 25-man roster, the Rangers optioned left-hander Michael Kirkman to Triple-A Round Rock.
The additions of O'Day and right-hander Tommy Hunter, who was activated from the disabled list on Friday, will give the bullpen a boost, but Rangers manager Ron Washington said the Rangers are not done seeking relief help.
Hunter made his first appearance of the season on Saturday night, relieving starter Derek Holland in the first.
He was removed from the game in the sixth when he appeared to be hit in the left foot on a line drive by Florida's Emilio Bonifacio. Later, the Rangers said Hunter wasn't taken out due to injury.
