Knuckleballers are a rare breed when it comes to big league pitchers. There have been only 26 pitchers to use the knuckleball as their primary weapon in the Major Leagues since the early 1900s. The lack of overall data has led to more questions than answers about what outside forces make that type of style effective. Does the ball have better movement when exposed to the elements or is there an advantage to having a game inside the controlled atmosphere of a dome? With R.A. Dickey now the bona fide ace of the Blue Jays' pitching staff, these are the type of questions people around Toronto have begun to ask.
