KISSIMMEE, Fla. — Braves rookie shortstop Tyler Pastornicky, who has struggled all spring, broke out of his slump by going 4 for 5 with an RBI to lift his spring average to .224 in a 5-5, 10-inning tie with Miami on Thursday. Pastornicky said he just needs to keep the pressure off and have fun. "I've been working hard," Pastornicky said.
