Here is a story that tells you all you need to know about the motor that runs inside Halladay. He reported to Phillies camp this spring with 148 wins, a $20-million-a-year contract and, while about to turn 33 years old, four straight seasons in which he finished no worse than fifth in Cy Young Award voting . . . and decided he needed to learn a new pitch. And so he simply mastered the changeup.
"Just means I'm getting old and need something new to trick 'em," Halladay joked recently when I asked him about it. "That's what happens when you hang around Jamie Moyer."
