|4-seam circle change|
and/or off-set fastball
4. Try an off-set fastball. Pitchers throw a fastball using their index finger and middle finger on top of the ball. "Off-setting" means placing your middle-finger and ring-finger on top of the ball instead. This finger combination uses less strong fingers so the velocity of the ball coming out is usually less. Many times this grip evolves into the popular circle change-up.
