Knuckleball

A knuckleball or knuckler is a baseball pitch flung in order to minimize the rotation of the ball in flight, initiating an inconsistent, unconventional movement. The absence of twist creates vortices over the sewed seams of the baseball throughout its trajectory, which in turn can create the pitch to change heading – and even corkscrew – in mid-flight. This makes the pitch troublesome for players to hit, and yet troublesome for pitchers to control and catchers to get; umpires are tested also, inasmuch as taking after the way of the ball makes it challenging to call balls and strikes.
