Jered Weaver, who is 15-1 for the Angels this season, takes the mound against the Mariners on Sunday. Weaver is currently tied for the second-best single-season winning percentage in history (.938, with Cleveland's Johnny Allen, who went 15-1 in 1937). Roy Face, who went 18-1 for the 1959 Pirates, has the best winning percentage in history. "I've never been a numbers guy, man," he said. "I don't really pay attention to all that stuff. I just go out there and try to give us a chance to win, and that's all I really care about."
