This one applies to the "cut underneath the ball" type of curve. It's a little cue that has been helping my pitching students learn the pitch faster. It seems to be the key to success.

We've been putting a lot of emphasis on leading the elbow, and getting it in front of the hip. It's that getting it in front of the hip thing that has been the key.

When the elbow gets in front, it sets up the proper angle to cut not only under the ball but across the body from right to left. It helps get better side spin on the ball.

When the elbow stays on the side, or behind the hip, it tends to make the ball go straight. You may get the correct spin on the ball, but it won't get the right to left angle that will help it break.

When you get in front of the hip, though, and get the hand underneath the ball of course, you can get the nice, tight side spin that leads to great ball movement. It's a thing of beauty.
