ARLINGTON -- Rangers pitcher Roy Oswalt, who is sidelined with tightness in his right forearm, played catch on Friday and will try again on Saturday. If that goes well, he could have a bullpen session early next week when the Rangers are in Anaheim.
Oswalt is unavailable to pitch out of the bullpen. His last outing was a two-inning start on Sunday against the Rays that was cut short because of discomfort in his forearm. He tried to throw on Thursday but still felt more discomfort.
"It wasn't terrible, but ..." Oswalt said.
Oswalt is 4-3 with a 6.29 ERA in nine starts and four relief appearances since signing with the Rangers at the end of May. Opponents are hitting .328 off him.
"We just have to keep going until he gets better," manager Ron Washington said. "You're always concerned when something is nagging. You hope by now it's gone away, but it hasn't. It's unfamiliar territory. He's never had an arm injury. It could be he's a little tentative, we'll just have to wait and see."
