As a pitcher you got to play they hand your dealt. Fast pitchers tend to be either tall or average height with more mass. Concentrate on spin and movement. When you try to make a smaller girl fast you tend to get her right in that sweet spot speed where hitters tee off on them.Appreciate this post - DD is shortest one on her 12u team. Seems like she is the only one who hasn’t grown and as a pitcher she’s been frustrated that her speed isn’t picking up like the others who have grown taller. She’s a lefty and is working on her slapping and bunting. It’s hard to not focus on height when you’re in a team with all girls over 5’2” already and she’s only 4’10.
