when the ball is out to either side you will have to wait even longer so the ball is almost next to you. If you reach or even slide out to the side with your body then all of your momentum is going out to the side. You will have to then stop that momentum and redirect everything back towards your target. Letting the ball get deeper on balls to the side will help maintain your direction and allow you to use your front side more.
The video up on baseballwebtv deals with a different way to receive (like Charlie Obrien-but that was a post from a couple years ago). I will check with tom this weekend in jupiter to see if the footwork feed is up. If you are in Jupiter you will see me doing extra work with our catchers and a couple others from other teams that have been with us over the year. I am managing East Coast PG Teal so feel free to say hi!
