I played around with it and got pretty good at it. Did your knuckleball have at least two different breaks? My best ones always had two. The first break was small and the second break was big in a different direction. My weaker ones had three breaks, but not big. Usually because I overthrew them. The ones with either no rotation or too much rotation were flat and a batting practice pitch. I used to throw them to my younger brother that was a catcher and had all the gear. A lot of the time he was trotting back to pick up the ball. I did pick up a tip from Hoyt Wilhelm. He told me that the last break is usually 180 degrees opposite from where you release the ball. In my experience it was usually true, but not always. It is probably due to how many rotations you expect before getting close to the plate. I would vary my finger positions when throwing them. And pitching a knuckler with a tailwind sucks. To get any motion means that you have to throw it hard and if you throw it hard it doesn't move very much. Throwing into a headwind is easier to get motion, but if it is a strong headwind it is crazy and you have almost no control. It flies all around. A light headwind is ideal for a knuckleball pitcher.
