Coaches are looking for potential, show arm strength and athletic ability. Video showing him asking for help and then throwing it around are of little value as does watching him jog to backup 1st base.. As another poster suggested shoot mostly from the 1st base side so the viewer can see the glove and hand work and zoom in, the viewer doesn't care what the pitcher etc are doing. I would not show the kneeling throw downs between innings, that is just a waste of video tape and time and might convey the wrong message to some coaches ("too cool for school"). The throw downs need to be taken seriously, scouts do pay attention to the in-between innings throws. I would also get rid of the pop up at home plate and add one that shows his athletic ability to chase one down. More clips, shorter duration all in the runner ready position.
imho Tee work and wearing the hat backwards can be cut.
I don't know if that's his school hat at the beginning but I'd go with a more neutral looking hat instead of something that might be an UoArizona hat.
Good luck.
