Where can I research alternate golf grips for swinging a club?

A baseball grip where you place the left thumb close to the knuckles and not on the shaft will work just fine. A ten finger grip has the thumb running down the top of the shaft and may cause you some trouble. I played a couple of times with a very good player who used the baseball style grip and he was a very good ball striker. He did position his hands on the club in a very conventional manner and by looking at his grip it was hard to detect that his thumb wasn't on the club. He started gripping the club this way as a teenager after spraining the thumb while playing baseball. You may have to invent your own way of gripping the club but don't be afraid to try the baseball grip or any other that may suit your injury. Try anything but don't give up. Good luck
