Great arm but wild

Drill work. Lots and lots of drill work. One knee/two knee/ten toes/load & go/towel.

My husband played "target" games with son. They would stand opposite each other and try to hit the glove. Husband would move his glove around and they placed bets - goofy stuff you know but with some reason for son to try hard - like who would mow the yard next or having to walk the dog the next five times. Finally son kept winning, so they stopped...

MTH and 55mom have some great suggestions. I also think that drill work contributes greatly to a young players development. I also like to include the figure eight with the ten toe drill.
I think that 55mom's suggestion is similar to the eyes to the glove or nose to leather follow through and would be good for younger players, keeps it fun.

Some other things to consider might be making sure the young guy is moving through the ball as he recieves it and after receiving the ball does he begin to bring it to the throwing shoulder?

Another thing to consider is whether or not he uses the right arm arc to make a throw from a specific distance. A long throw requires a long arm arc versus a short throw that will require a shorter arc. Here is where I watch to see that a player is consistent. Does he keep his elbows up and his hands toward the middle of the body on the pivot to make the throw?

I see some basic problems that lead to loss of accuracy that include dropping or elevating the elbows,early hand break and poor use of lower body.
I also like to see the front side stay closed (chin, glove side elbow and front hip outside the front knee and also the outside of the front heel facing towards the target.

Again I like to spend about thirty minutes each time working on drills. Dependent upon needs I might use the flick or sitting drill to focus on ball rotation for accuracy.

Coach, I am sure that I am not really telling you anything new, but maybe it will jog your memory and help you remember some other concepts that you may know and be able to implement with your young protege. Best of success in helping him reach his potential.

Hey ts, you might consider telling the kid/parents to get a pitch back, then wear it out. There are many on the market; some with simple square targets and others with elaborate imitation batters and pocket to throw through like the one at this link.

My son wore out three before I found one that stood up to his routine. He was always outside throwing at it when I was not able to throw.

coach0 and mth both mentioned the ten toe drill... never heard of that one... what is it?

Gater022, we use this drill to emphasis accuracy and velocity, (the release point). It focuses on weight and energy transfer through the body.

The drill is performed by the players standing and facing each other with feet about shoulder width apart. There is slight flexion in the knees to help with balance and transfer of energy from the ground up. The player throwing holds his hands together at the chest midline and rotates and points his front side shoulder at his partner. The emphasis is to keep elbows at chest height, and keeping the eyes focused on the target. (Focus is on weight transfer, upper body mechanics and release). Hope this helps.
