HOW TO PROPERLY CATCH A HIGH IN THE SKY FLY BALL.
First, you try to get under the ball. Then you lift your glove up to the place YOU think it will land. Now, you have to make your thumb pointing up when you have your glove up. As it starts getting closer to your glove you move your glove to where it will land. Then once the ball hits your glove you immediatly close it, and hastily put that other hand of yours on top of the opening of the glove so the ball won't pop out.
