Righthander Roy Oswalt, who has been on the disabled list since June 24 with lower back inflammation, has pronounced himself ready to return to the Phillies rotation.

Oswalt went 6 innings in a rehab start for Triple-A Lehigh Valley Monday night, allowing 2 runs on 7 hits. His fastball was consistently 90-91 and occasionally hit 92. He threw 90 pitches, 61 for strikes.

He's expected to rejoin the team in Denver on Tuesday, throw a bullpen in San Francisco on Thursday and then start against the defending world champion Giants on Saturday or Sunday.

Asked if there was any reason why he wouldn't, Oswalt grinned.

"No, I don't think so," he said. "The back feels great. I don't have any pain. Right now it's just getting back into that rhythm of pitching. Taking five weeks off and being off the mound, you've got to get back in the groove of things. I'm probably not going to throw a no-hitter first night out. Wish I could. But I feel pretty good so it's just a matter of executing pitches."
