ARLINGTON -- The Rangers are switching Scott Feldman and Roy Oswalt in the rotation. Oswalt, who threw in the bullpen on Friday, is now scheduled to pitch on Monday against the Angels.
Feldman is being moved up and will pitch Sunday against the White Sox. The Rangers decided to give Oswalt an extra day of rest to recover from the tightness in his lower back.
"There's nothing wrong, we just decided to switch it and give Oswalt an extra day," Rangers manager Ron Washington said. "Feldman is good to go on Sunday."
Oswalt was scratched from his last start on Monday. He will be pitching on 12 days' rest when he takes the mound on Monday.
"I should be ready to go. I feel great," Oswalt said. "I could go tomorrow. I threw a bullpen today so I could throw either Sunday or Monday. They told me I was going to throw Monday. It doesn't really matter."
Oswalt improved to 3-1 in his last start July 17 against Oakland, giving up one run on three hits over 6 1/3 innings while striking out six and walking none during a 6-1 win over the A's. He has posted a 5.22 ERA and struck out 25 batters in 29 1/3 innings over five starts.
"My job is to eat up as many innings as I can," Oswalt said. "We've got some tremendous arms, some tremendous pitchers. Derek [Holland's] coming around. He threw really well his last start. [Yu] Darvish has been throwing great. [Matt] Harrison's been lights-out. You've got three guys that have been throwing great all year. All you try to do is continue that throughout the starting five."
