Darrell Rasner left his outing against the Mets with a broken index finger Saturday that could sideline him three months, becoming the latest Yankees starter to go down with an injury. Hit on the right hand by Endy Chavez's one-hopper, Rasner lasted only nine pitches. He left Shea Stadium to be examined by a hand specialist and surgery was recommended. "It turned out to be a pretty bad break," general manager Brian Cashman said. Starters Chien-Ming Wang and Mike Mussina have returned from hamstring problems, but the struggling Yankees are still waiting for Phil Hughes (hamstring) to get healthy and Roger Clemens to round into game shape. Jeff Karstens is recovering from a broken leg and Carl Pavano is also sidelined -- again -- with an elbow injury.
