Pedro Martinez was very upset following his performance in Pittsburgh on Friday night. "I was on the verge of snapping," he admitted. Willie Randolph could see that, so he walked over to him and asked, "You feeling OK?" He insisted he wasn't hurt, insisted that whatever was getting him down had little to do with the physical ailments that have sabotaged his season, starting with his toe, working its way up to his calf and his hip. "I expect a lot out of myself," he said. "I wanted to prove something to my teammates."
