Roy Halladay (shoulder) will head to the Phillies' spring training complex in Clearwater, Florida on Thursday. Halladay threw a five-inning bullpen session on Monday evening and came out of it feeling strong. He'll start facing live hitters down in Florida and could rejoin the Phillies' starting rotation at some point in late August or early September if all continues to go well. The veteran righty underwent shoulder surgery in mid-May.
