Separate your hands and abduct (stride) with your left leg toward home. The stride should be a comfortable one, so it shouldn't be too long. Drop your hands inferiorly (away from the head) and then seperate them. Extend your right arm back and up to a 90 degree angle. Pronate (turn outward) your throwing arm and hand, showing the shortstop the ball. Use your left arm to aim for your target. Your elbow should point toward the catcher. Keep your glove tucked in.
