Do you mean the span is still too long? If so that is probably what is causing the base of your thumb to press so hard that it is pinching the nerve there. Get this fixed immediately, forward pitch with too long of a span can cause serious hand injuries. That is why I tell everyone to make sure their span is right before venturing forward with the thumb pitch.

yes, i mis-spoke. the span is still too long. it's still right at 4" which is about 1/4" to long. i can get out of the ball easily without pain in my thumb if i concentrate on trying to press my finger nails into the to the top of the finger grips. this allows my thumb to be able to pull out of the hole straight and not bent.

i'll prolly try bowling with it a little bit and then end up going back to the Pro Shop to lengthen it again.

Does this mean that moving the thumb pitch forward or reverse will not have any affect on the span? I was considering moving forward a bit, but was concerned about a span change.

I second getting this fixed. You're going to end up hurting yourself if your span is to long. There's also a nerve at the base of your thumb that you can end up aggravating and it will send a shooting pain up your arm when you swing the ball. Just get it fixed.

You need to shorten the span 1/8" for every 3/8" of forward pitch or lengthen the span 1/8" for every 3/8" of reverse pitch.

If you are at 0 pitch and the edge of the finger hole is right at 1/2 way between the first and second knuckles with the thumb in the hole and the fingers laid relaxed across the holes as I have described repeatedly here, and you want to go to 3/8" forward then you will want to shorten the span 1/8" to allow the thumb to clear the edge of the hole.

yes, i noticed this problem. if i put my thumb in first and don't put my fingers in all the way my thumb would come right out but if i put my fingers in first and then my thumb the edge of the hole is to far away and almost forces me to knuckle the ball to get it out of the hole almost making it impossible for anyone to get it off the hand!

span is so [censored] important and i didn't really realize until i went with this forward pitch. anyway, the ball will hopefully be fixed before leagues start up as currently it's my only ball!

update:

got the ball drilled with a shorter span. went from about 3 (15/16)" span to 3 3/4" span and it feels better. i feel absolutely nothing on the thumb now which is good. i can't quite relax my hand or else it seems like it wants to fall off yet i'm not sure i can make it tight enough or else it will stick. could just be the way i'm releasing it but it feels as though an even shorter span may help a little.

here are some pics to show you guys.

you'll notice the thumb is still doing that. i can tighten it up but i don't think the ball will come off my hand if i do. i do notice that if i don't put my fingers all the way in the inserts it comes off the hand much cleaner which is why i think maybe a little less span would help even more.

also, i'm kinda confused because i can throw the ball a few ways and get it off my hand but i'm not sure which is correct or should i say best. one way is to keep the thumb straight but grip the fingers. the other i do is keep the thumb straight but try to straighten the fingers against the top of the thumb grips and the other is to keep the fingers straight and do nothing with the fingers.
