Without consulting either his doctor or Dodger trainers, Pedro Guerrero (pinched nerve in his neck) took batting practice before Wednesday night's game. Dr. Robert Watkins, the specialist treating Guerrero's injury, had told Guerrero to wait until after the All-Star break before trying to take batting practice. But Guerrero took several batting-practice swings, apparently without discomfort. "As far as I know, he did it on his own," trainer Bill Buhler said. "We talked about it before, and he knew about (the timetable). But I guess he felt good enough to hit." Buhler also said that Guerrero was supposed to be having daily traction treatments but had stopped them. "He didn't do it very religiously," Buhler said. "He just stopped coming in, and we stopped nagging him about it."
