Now when I say "fix things," I'm talking about mechanical issues. Changing your body physically only takes a few weeks for the average athlete. But changing something mechanically takes hours and hours of drill work. A pitcher's body and muscles are used to doing things a certain way. When you go and attempt to change something, it is very difficult to make your body adjust to it. It's all about muscle memory. The more you do something physically, the easier it becomes to perform. I hate when coaches, pitching coaches in this case, tell their players that they're not going to try and change any mechanics. Well thats fine if every pitcher on the staff has professional pitching mechanics. If kids are doing something wrong, it should be fixed. When a coach says he is not changing anyones mechanics, it means only one thing: he simply doesn't know how.
I am at the point in my pitching career where little things are enormous things. This summer I decided to video tape myself pitching in my backyard. I had been watching some videos on YouTube of professional pitchers, pausing at certain times in their deliveries. Then I watched the video of myself and compared.
In the above picture, Andy Pettitte is just about to throw to home. When you look at this photo, focus on two key areas: his chest, and his back leg. As his arm starts moving towards home, his chest will be out in front over that front leg as far as he can get it. His back leg is fully extended which brings him closer to the plate and creates all the power for his pitch. Pitching velocity starts with a transfer of weight from the back leg, through your core, and onto the front leg. This allows the arm to work like a whip when throwing the ball.
In the video of myself, I noticed that I was not fully extending my back leg in my delivery. Also, my chest was not far enough over my front leg at release point. This means I am not generating the maximum amount of power from my lower body and I am not releasing the ball out in front like I should. These two mechanical issues are what I need to fix during my summer break. I will keep you posted on how it goes.
