I have played against Larry Ray and Arizona a few years ago when I was coaching at Simon Fraser University (lost 4-1 with Finch on the mound) but I had a chance to talk to Coach Ray and he is a great gentleman and a passionate about the short game.
Your time will definitely be worth it. He was actually sort of a pioneer in the 1990`s turning AZ into a short game (not even counting their power side) powerhouse and is easily recognized as one of the leading expert on the topic of slapping. Has 2 videos out on the topic as well I believe.
I strongly encourage you to go.
