Lately I feel like I forgot how to bowl. My games been inconsistent. First three weeks of league and I'm sitting at a 153 average feeling I'm back in youth league. It's like I'm fishing for that ideal backswing and release and it's tanked my average 45 pins for the start of the season. I have an appointment setup with my coach to try and bounce back but I wanted to ask if there were any tips from anyone on here to help "reset" persay.

Basically I feel like every week this far my mind if trying to get my hand to do something different with the release. I'm grabbing it for sure as well, I developed a nice callus on the interior side of my thumb from I assume knuckling it.

I could be wrong here but to me, its seems like you are pulling the ball down. Wait on the ball to fall. For me, fast feet create this issue. when I slow my feet down, everything is better. 

Before you start making changes to your game try to find out if the house has changed the oil pattern.  --  JohnP

no matter the pattern, you must stick to fundamentals.
when you go to practice, do it without scoring and throw at each and every spare shot.

You may want to see if there is a coach available, always good for someone else knowledgeable to watch and see whats going on
