It's an exclusive club: Pitchers who rely on the knuckleball, and win, in Major League Baseball. It's one the most difficult and unpredictable pitches in the game. Only about 80 players have ever used the knuckleball consistently in the major leagues. Even fewer were successful.
New York Mets pitcher R.A. Dickey is one of the only active starting pitchers in professional baseball who uses this slower, methodical pitch. He's chasing 20 wins, and a possible Cy Young Award, in the 2012 season.
Along with famed Red Sox knuckleballer Tim Wakefield, Dickey is one of the subjects of a new documentary, <em>Knuckleball!</em> Dickey joins NPR's Neal Conan to discuss the art of the knuckleball, and a life of ups and downs in the world of baseball.
