Roy Oswalt (hamstring) hopes to throw a bullpen session this weekend. Oswalt thinks he's ahead of schedule after doing resistance training with weights, increasing the pace of his running and playing long-toss on Monday. "It's going pretty well," Oswalt said. "They're looking at me kind of funny, like it's going too fast. It's not going fast enough for me. I know they don't want to push me until it gets completely healed, but it feels great right now." If Oswalt is able to throw a bullpen session this weekend, a return in early August is likely.
