Hey guys, I am new to this board. I AMA 15 year old rhp, I have a 4 seam, 2 seam, circle change, and a 12-6. I have recently noticed that my 2 seam and change up are not doing what I want them to. My two seam is not breaking down and towards my throwing hand, and my change up is not dropping as much. I have located the problem through looking at videos of myself pitching, and I realized I am not pronating. When I try to focus on pronating when practicing, the pitches are slower, more dull, and wild. Is this just because I am trying something different (pronating)? Or is there a further problem?
