All are welcomed. I'm sure you know video is better. Not knowing your sons age, I would say from pics this was outfield throws. He looks good. Read through the fielding posts, the ones marked throwing. Alot of good info. I'm sure your like most parents that throw well, but aren't really sure how you really throw. Pay attention to how you throw. Pay attention to how your front thigh rolls over as you start your throw untill release. Check at Tweeks at AB Athletics, he has done alot on proper throwing. So has FiveFrameSwing and wellphyt on this site. Throwing is to hitting as hitting is to throwing.
