thumb question

[Baller]

I'm a new bowler, but when I bought my ball, the guy at the pro shop gave me a few quick lessons/tips. He told me that the nail of the thumb should be up against the "wall" of the thumb hole. It makes sense, as it just slides against your nail on the way out. If you put the pad of the thumb up against the ball, it may have too much grip and not come out on release, which is what you were describing. I hope this helps some.

I worked with my coach today, Fred Borden. I didn't even tell him about my thumb issues I've been having. I just asked him to watch me throw a shot and analyze it. So he did, and he pointed out that my posture was bad. Instead of keeping my upper body upright I was bending at the waist and raising up as I was releasing. This was causing me to release the ball way too early OR way too late. This gave me my thumb issues.
As soon as I became more upright and bent more at the knees, my release window tightened up and I got out of the ball cleaner. I strung 6 straight strikes after that adjustment and got out of the ball cleanly every shot. Thanks coach!
