12 Yr old's Pitching Mechanics

Jeff is 5’3 125 In this video he is throwing from 60’6 inch. Any tips or thoughts are welcome.

First why is he throwing from 60’, is he playing that far up in age brackets, isn’t the first possible move to 60’ at 14U is most places and 15u generally?

To comment on the video is almost impossible, you should invest in a tripod and a much better angle(from the side and the back) to get a true look at what is going on. Throwing mainly fastballs too, looks to be 2 curve balls, a change and a fastball in the video.
