The Texas Rangers have placed utility infielder Andres Blanco on the 15-day disabled list with a stress fracture in his lower back.
Texas made the move before Friday night's game against Oakland, and purchased the contract of infielder Omar Quintanilla from Triple-A Round Rock.
To make room for Quintanilla on the 40-man roster, the Rangers transferred right-hander Scott Feldman to the 60-day disabled list. Feldman is still eligible for activation since he hasn't pitched this year while recovering from offseason right knee surgery.
Texas also announced that right-hander Dave Bush cleared unconditional release waivers and is a free agent.
Blanco is hitting .223 with two homers in 24 games this season.
