bowling release, My Ball is rolling over thumbhole

[Ucci]

I am having trouble with my release. I had to stop bowling for a year due to work related injuries and I am finally being let go by the doctors. I went out and tried to bowl and my ball keeps rolling over the THUMB hole. I have no idea why. and I cant seem to fix it. Its tearing up my bowling game! can anyone help me, any ideas how to fix this???????????????

do you turn your hand at all?

during my push off and the rest of my swing path I am inside of the ball the at the bottom I come out of it as I usually do (but that's no the case). Its not forward roll really, it has side spin but it rolls all the way from release to pins with a constantly thumping noise. my hook potential has gone down due to this. I'm a cranker and I'm unleashing around 500rpms and playing 15 to 10 with 18miles/hour and its barely coming up. just so confused and fed up with it

is it possible that the ball is damaged? if the core is loose this could happen...

Try slowing everything down and remember to lift the ball with your fingers at release.

Being a cranker with reasonable speed and above average revs I would guess you were a high track player to begin with. Axis tilt is the leading cause of rolling over the thumb hole. Playing the inside part of the ball correctly you will have good side roll/rotation. Once you fix the tilt of your rotation the movement will return. Axis tilt is controlled by when and where the thumb exits the ball. High track players have less margin of error in this area due to the track being so close to the holes to begin with. Without any video my best guess would be your timing is a tick off. Most crankers are late to begin with so you're probably a millisecond earlier than you were before.

Would it do any help if I change the pitch in the fingers or thumb maybe? Just throwing out suggestions maybe. Because I tried bowling earlier today and slowing down and really trying to focus on my timing and what not but seems to still roll over the thumb.

I would go to your local pro shop and have them check your ball to see if core is intact,if it is I would have them measure your hand span,finger & thumb pitch.

Alright man, sounds good! thanks. . .However really hope its just my pitches or timing way off. Because all of my balls are rolling over thumb hole, I better not have all of my balls broken cores or loose lol
