Phillies right-hander Roy Halladay left his start against the Cardinals on Sunday afternoon because of shoulder soreness. Halladay surrendered the fifth grand slam of his career to Yadier Molina in the first inning, but worked a perfect second inning. The two-time Cy Young winner pitched with the injury the last few innings of his last start, and cutting back on throwing between outings didn't help. "Worried? Yeah, definitely, I'm concerned," manager Charlie Manuel said. "Pitching is one of the big things on our club and when guys miss a turn, it concerns me."
