In the wake of Giants catcher Buster Posey's serious leg injury, there has been a lot of debate about the future of collision plays at the plate. Yankees general manager Brian Cashman says that he would be in favor of making a rules change that would end contact between catchers and runners in collision plays in exhibition games. "I would make those changes in the spring," Cashman said, "in exhibition games that don't count." A few years ago, New York lost catcher Francisco Cervelli for three months to a broken wrist on a home-plate collision in spring training. Cashman said he was not ready to take the step of altering rules as an effort to eliminate catcher-runner contact during the regular season. "Second basemen and shortstops are vulnerable on double plays, outfielders will sometimes crash into a wall," he said. "Catchers are vulnerable [in collisions], for better or for worse."
