A straight pitch is achieved by gripping the ball with the fingers across the wide part of the seam (called a "four-seam fastball") so that both the index and middle fingers are touching two seams perpendicularly. A sinking fastball is thrown by gripping it across the narrow part (a "two-seam fastball") so that both the index and middle fingers are along a seam. Lateral motion is achieved by holding a four-seam fastball off-center (a "cut fastball"), and sinking action with a lateral break is thrown by splitting the fingers along the seams (a "split-finger fastball").
