bowling release, My Ball is rolling over thumbhole

[Big Nick]

I had a similar problem, albeit with a conventionally drilled ball, and it was all related to how my hand was positioned at the time of release. Make sure that you're staying behind the ball and not turning it too early. If I had to guess, you're tending toward a full-roller release. There's a video around here somewhere that demonstrates a drill to help with this problem. I'll see if I can find it.

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

Lol if it's happening with every ball you use there is no way its a broken ball, the only reason i said it was i saw a fellow bowler who has a loose core bowl and the thing was thumping down the lane lol (he had left the ball in the car over night in -30 degree weather and thought he would throw it the next morning)

There is also a chance the during the time you took a break and your return that your PAP changed raising your track. I also think a quick trip to the pro shop would help solve this. Is this the only ball doing it?

My question would be where is the oil track on your ball ? Was it always in the same spot or did it change when you started bowling again? Try changing your wrist position, cocking it, so your fingers are at 9 or 10 O'clock under the ball. As Bill mentioned this will change the axis the ball is rolling on and "should" get it off of the thumb. If you're hitting the thumb on all of the balls you own, and they're all drilled a little differently, the I'd say it's your hand position at the point of release. Have someone watch your release (very closely) or video your approach and release and run it back in slow motion to see exactly where your hand is upon release.
