ARLINGTON -- Roy Oswalt knows there is a possibility the club could trade him before Friday's deadline. He was told three weeks ago that he has cleared waivers.

"I've never been through this before," Oswalt said. "I don't know what the process is or what to do. I don't have any say-so in the matter. If they trade me, I'd have to go. I'm just going to do what they tell me to do."

The Rangers signed Oswalt at the end of May to reinforce their rotation, and he has since been moved to the bullpen. He has made it clear that he prefers to start but has accepted his role.

He's not sure what his role with a new club would be, but he is not as unhappy as people have assumed he would be as a reliever.

"A lot of people have written a lot of good opinions," he said. "I'm great. ... I'm good. I'm just waiting for them to call down there and the phone to ring."

Oswalt said that when he signed there were no promises that he would be a starter, but he admits that the possibility of going to the bullpen was not something he completely expected.

"If they [had said something] up front, it would be a different situation," he said. "It caught me by surprise, but that's water under the bridge."

Manager Ron Washington said that Oswalt's role is of a long reliever, and he is not sure if he'll get another start this season.

"I can't predict. Let's just wait and see," Washington said.
