There's a good story in the New York Daily News about Tom Glavine changing his style of pitching for success in the 2nd half of 2005:

He and Mets pitching coach Rick Peterson talked during bullpen sessions about what to do. Peterson recalled Glavine throwing nasty breaking balls when warming up and then not using them enough in games. "Why don't you use it?" Peterson asked. "He said, 'I don't know, I just never have.'"

At one point in their discussions, Peterson delved into golf analogies to make a point. Glavine had once played golf with Tiger Woods, Peterson said, so he was asking Glavine questions about what Woods was like. Then he reminded Glavine that Woods, at the time already the world's best player, had altered his swing. Maybe a five-time 20-game winner with two Cy Young Awards needed change, too.

"It's a lot easier to make changes when you're unsuccessful, but to have the courage to make them when you're as successful a pitcher as Tom Glavine has been, that's not as easy," Peterson said. "He rewrote his recipe."
