So after long studying maybe for about a couple years now I've started to notice a glide then push. I see pitchers such as the famous Nolan Ryan clip hiding around somewhere. That pitchers glide but then push with the post leg to only get hip rotation started. So would the push be has last minute has possible before front foot lands
Good question. Wish I had the answer. BUT, if you look at some of the video of Lincecum he most definitely has a very late ankle "kick" that gives him a bit of a late hop in his stride.
There really isn't a "push" at any point. At stride foot contact (SFC) there is backside drive of back leg. By this, I mean after the stride leg stabilizes the body, the back knee is pulled forward and inward aiding hip rotation.
