The Texas Rangers placed starting pitcher Colby Lewis on the 15-day disabled list on Tuesday because of tendinitis in his right forearm.
Lewis is one of four Rangers pitchers on the DL. The others are Derek Holland (elbow fatigue), Neftali Feliz (elbow inflammation), and Alexi Ogando (groin).
Lewis is 6-6 with a 3.51 ERA this season. In his most recent start on Saturday, he gave up eight runs on 12 hits, both season-highs, in four innings.
Scott Feldman will replace Lewis in the Rangers rotation and pitch in Thursday's game against the A's. Feldman had been moved out of the rotation and into the bullpen when Roy Oswalt was added. Feldman is 1-6 with a 6.00 ERA this year.
Lewis will be replaced on the roster by Martin Perez, who was called up from Triple-A Round Rock.
