Wednesday night's victory of baseball's Florida Marlins over the Arizona Diamondbacks raises a question: How does a pitcher's wind-up affect his success on the mound? Two superstar pitchers — Dontrelle Willis and Randy Johnson — competed in that game. The Marlins' Willis took the win. His wind-up is something of a spectacle. To discuss how Willis' flailing lends to his game, Robert Siegel talks with New York Yankees broadcaster Jim Kaat. Kaat is also a Baseball Hall of Famer and author of Still Pitching: Musings from the Mound and the Microphone.
