Dreaded low elbow


I don’t know the cause/effect of the following, but my 14u son seems to be throwing with a low elbow. He is also flying open, and as a RHP, is finishing almost facing the 1b bench.
I don’t know if the elbow is the cause of the flying open, or the effect, but it’s ugly to watch. And it produces a flat ball that’s easy to hit.
Any ideas how to fix?


Need to see video. Or need more details. For example, what specifically is flying open?


I’ll try to get some video this week.
It’s his front side that’s flying open.
Hie entire body rotates instead of having a downward tilt towards the plate and creating a downward angle on the ball. Instead, it’s a flat ball that’s easier to see and to hit.
