well, if it's just some fractures around the fingers or thumb, they shouldn't be to big of an issue for a while. If it's a crack that has started to go around the ball, it's done. I have 2 balls that started cracking last year while sitting on the ball rack in my heated basement. I looked at them yesterday, they are cracked in numerous places around the ball. Best bet would be to replace it. If by chance it's a newer ball or something your proshop drilled less that a year ago, you may be able to contact the manufacturer for a replacement. Regardless, I would email the manufacturer anyway, It cant hurt.
