Don Mattingly is moving up to Yankees' bench coach next season, a promotion that makes him the early favorite to one day succeed Joe Torre as manager. Mattingly rejoined New York in 2004 as hitting coach. Torre, hired by New York before the 1996 season, is entering the final season of his contract and isn't sure he wants to manage beyond 2007. "It's probably a step in that direction," Mattingly said Wednesday during a telephone conference call. "I want to have an opportunity to manage at some point."
