Consistency With my fastballs

This may also fall under the category of training advice but here goes. Im 13, im a pitcher and i throw strikes. But the problem is, is that I can throw a few strikes but not consistently. I can throw the ball straight, but I cant throw it exactly where I want it. Sometimes I can control the ball on the horizontal axis, but not the vertical, sometimes the opposite, sometimes neither. What are your techniques on throwing strikes and throwing them consistenty?

@LABaseballBoi37 Practice a consistent fastball motion, I wish could help more and be more specific but I don’t know other techniques.

Ok thanks. That’s ok, i appreciate all the help I can get.
