Roy Halladay wasn't particularly sentimental about his return to Florida Auto Exchange Stadium, his spring-training home for most of two decades. "I got sent down four times in the office back here -- the last time was to A-ball," the Phillies' ace said as he stood in the visitors' locker room after pitching two shutout innings in a 6-3 win Monday over the Blue Jays. "So I'll be glad to get out of here." Halladay can rest easy that another demotion isn't in the cards this season, but that doesn't mean he's resting on his laurels -- including last year's National League Cy Young award -- as he gets set for his second season with the Phillies. "I'm always trying things," Halladay said. "You're always trying to improve. For me, that's always the case." The checklist for improvements shouldn't be particularly long for a pitcher of Halladay's stature, but he attributes much of his success to his constant desire to refine his game. This spring, Halladay has his eye set on finding consistency with all his pitches. "I felt like there's times I was really limited to one or two pitches during the course of a game," he said. "If I can just find a way to keep things more consistent, where I always feel like I have more than two or three options, obviously that would be ideal." Halladay exclusively used his fastball and a changeup that looked particularly good, according to catcher Carlos Ruiz, but he has varied his repertoire during workouts and bullpen sessions.
