ANAHEIM, Calif. -- Texas Rangers manager Ron Washington had to make sure there was no misinterpretation as he discussed the progress of an injured player Sunday.

"Wait, I said, 'We need another picture,' not another pitcher," Washington said, smiling.

But, really, "pitcher" would appear to be an appropriate word to use, especially with the two bits of news the Rangers received before their rubber match against the Los Angeles Angels. Right-hander Roy Oswalt (lower back stiffness) was scratched from his scheduled Monday start against the Boston Red Sox, and recently activated Colby Lewis (forearm tightness) will be re-evaluated Monday and is likely to miss his start Tuesday.

The good thing for the Rangers is that the trade deadline is still nine days away. If things look bleak, there is time to make a move.

"The timing of it, with some of the other things we've got going on, isn't ideal," general manager Jon Daniels said. "But that's out of our control."

On Friday, Lewis appeared set to make his second start since being activated from the disabled list. Yet the right-hander did not play catch Saturday and skipped Sunday's scheduled bullpen session. He said he would visit Dr. Keith Meister on Monday to get another opinion on the persistent tightness in his throwing arm.

"If for some reason Colby can't go, we've got a plan," Washington said.

That plan would center around 21-year-old left-hander Martin Perez, who was pulled after only two innings Friday at Triple-A Round Rock in case he'd be needed. Right-hander Justin Grimm is the other option, according to Daniels.

"We're not going to panic," Washington said.

Other notes:

* Catcher Mike Napoli was penciled in at designated hitter for the second consecutive game. "I just want to get him another day off his legs and get him rested," Washington said.

* Washington said he was content with the way the Rangers played on the eight-game, three-city road trip coming out of the All-Star break. A win would give the Rangers a 5-3 record on the trip.
