[quote=“centerfield2150”]what should I do so you can get the file frame by frame? I’ve got the regular file sitting on my desktop, just let me know what I should do with it.[/quote]What format is the video you have? Can you please send it to me at firstname.lastname@example.org. It really makes a difference if we can see it frame by frame.
All of the advice so far has been about hip / shoulder separation. I don’t see a big problem there but the advice is still good. I’m going to add something that I believe is the biggest power robber you have. That is your arm action is inhibiting your ability to get to “full external rotation” with your throwing side upper arm (humerus). This is where the forearm has gotten to a point where it is laid back, horizontal as your shoulders square to the target. Chris O’Leary often speaks of Mike Marshall’s “reverse forearm bounce” with respect to this. I disagree with the term “bounce” here because, done well, it “loops” back, down, around, up, forward and on in a smooth, fluid motion, and is not a jerky “bounce”.
This is one of the most common problem I see in developing pitchers. The result is sort of a “push” with the arm rather than a whip. An extreme description of this is a “shot put” kind of throw. It’s very difficult to generate your maximum velocity without doing this well.
I’m eternally frustrated by not being able to post video directly here but, if you send me your email address, I’ll send some very good MLB videos of what this looks like and some thoughts on how to get there. It’s not easy to get there though. It takes a lot of work and patience.
The issue with your arm action that is causing difficulty in this regard is how you take the ball down and then, as it stays down there, you take it back behind your body (toward 1st base in your case as a righty). Then, and here’s where frame by frame would help, the hand / ball overtake the elbow on the way up. This path makes it very difficult to get any whip on it.
My suggestion is to stop swinging the ball down and back with the straight arm you exhibit. It’s fine to straighten out on the break from the glove, just get the elbow bent early and lift straight up with the back of the forearm, thumb under the ball. The hand should not overtake the elbow on the way up until the entire arm is horizontally oriented at shoulder height. Then the ball continues it’s arc up and back. If this is done with the proper timing, the shoulders and elbow being fired at front foot landing, the result is the looping action I spoke of. This is incredibly difficult to describe in words.
