Why is this?
Because if you are facing the ball, your bat is actually one to one and a half feet to the right of your body when you are standing ready and keeping yourself able to go to the forehand or backhand equally easily. So if you point your bat directly at the ball, you will actually be in a slightly backhand waiting position.
Pointing Your Bat at the Ball - The ProblemSo what, you might say? Well, if you are pointing at the ball just like the player in the diagram, and the opponent hits the ball at the area between your bat and your belly button (your playing elbow, you are already in position to hit a backhand stroke - so guess which stroke you are likely to play? That's right - a backhand.
The problem is that you should actually be hitting a forehand when the ball comes to this area. Since your racket is pointing to the wrong location, you are more likely to play an awkward backhand than the forehand you know you should play.
