First Outing of The Year

Hey guys… if you have 3 minutes to review my sons pitching I would appreciate any feedback, This is his first season pitching from 60 feet.

Link to the video.

make sure that when he pitches, he lands straight towards the plate, because the pitch will otherwise be pulled off to the left or right

correct me if I am wrong but I believe I see that he is landing on his heel when he is land on the mound. That only causes you to what to my knowledge is to fly open and lose velocity etc.

How fast is he throwing currently?
