For some reason or another I lost the edge I gained a week ago. One night I just forgot how to throw. I was pinpoint for about a week, but now I can’t hit my pitchback. I get frustrated and down on myself, do I need to have a mound visit with myself? How can I regain my confidence/composer?
You may have unknowingly changed something in your mechanics and introduced a flaw that leads to control problems. Check your mechanics (or have someone else who is knowledgeable enough do it).
Also, start throwing from a shorter distance and gradually work your way back as you get your control back. Small, incremental successes will help restore your confidence.
