ARLINGTON -- Martin Perez will get three to four days off and go into the Rangers' bullpen. Perez allowed one run over six innings in a start against the Red Sox on Tuesday, and finished with 98 pitches.
But Roy Oswalt is returning to the rotation on Sunday after missing a start because of tightness in his lower back, and Scott Feldman is also being used as a starter. That means Perez has to go to the bullpen.
"We're not going to six starters," Rangers manager Ron Washington said.
Perez is unavailable for a few days, but Washington said the Rangers' bullpen is sufficiently rested and did not need to go get a fresh reliever. The Rangers have an off-day on Thursday, then follow up with Yu Darvish in the series opener on Friday against the White Sox, and Matt Harrison on Saturday.
"Hopefully they can take it deep," Washington said.
Perez is 1-1 with a 4.26 ERA in three starts and two relief appearances during his two stays with the Rangers this season. He may not be here much longer, because the Rangers are hoping Mark Lowe will be ready to come off the disabled list by the end of the homestand. He is expected to pitch Sunday for Double-A Frisco on a rehab assignment.
