When framing, you need to extend your arm, go get the ball, and hold the ball for the umpire to see. Roll your wrists toward the plate, but don't pull the ball. Roll and extend in a smooth manner and avoid jerking or snapping the glove.
On low pitches, roll your wrists upwards. It is important to give the umpire a good view. The catcher and the umpire need to work together.
