Knuckleball

A knuckleball (or knuckler for short) is a baseball pitch thrown so as to minimize the spin of the ball in flight. The lack of spin creates a chaotic airflow over the stitched seams of the baseball and produces an erratic, unpredictable motion. This makes the pitch difficult for batters to hit, but also difficult for pitchers to control. The challenge also extends to the catcher who must make an attempt to catch the pitch, and the umpire who must determine whether it was a strike or a ball.
