My son has been working on his sidearm delivery for the past six months. He experienced a lot of pain in his elbow throwing 3/4 but did it for two seasons. He threw 25-30 pitches and had to come out due to pain in the elbow. He threw that way each season but was told not to do it. He said he feels more comfortable at this angle and has MUCH better accuracy and velocity.
I noticed that he likes to drop low to the ground and I tried to correct that (forcing him to stay taller) and his accuracy disappeared. I have seen a lot of Japanese pitchers drop low to the ground like he does.
Can you see anything that looks correct?
Is there anything that he can be doing better?
He has been trying to crossfire and trying to not over do it. Looking at his pitches, they stay low and move from right to left and sink. Is this just how he pitches (or type of pitch) or is he missing the running fastball from sidearm pitchers?
Thanks for you help.
