John and I talked about this not long before he became ill. He said he’d been studying video of contemporary elite pitchers and had come to the conclusion that 45 degrees +/- was advantageous for both spin and speed.Her mother and I were taught to open at all cost from John Gay and she keeps telling them to open up. So there is an issue with being to open.
So, the opening and closing (if you call it closing) happens really fast. It’s not a 2 part move.
Great man and greatly missed…
