Quick Question

When you pitch do you put all you have into it 'cause when I do it flies all over the place but when I take a little off it it is very accurate.

Well I don’t overthrow, I throw controlled, but I do throw as hard as I can, keeping my mechanics in check, with my timing.

What you probably do, is change something in your mechanics, or upset your timing, or both. Post some videos to get analyzed in the mechanics forum.
