throwing strikes

It might be something in his mechanics..it's kinda hard to give any help without seeing him. I'm 15 as well and lately have been real into looking at my mechanics. You might want to have him and others look at his mechanics too.

Get video clips. Take clips of bad throws and good ones. The answer is usually there somewhere.

There are drills you can do but unless you know what his tendecies are then you won't be able to help him when it goes backwards again.

Good luck.

How do I get good video clips? Do I just video him from the side, behind, and front with a digital camara? Then, how do I post it for all to see? I am new to this, so I am sorry for being so elementary.

Take a look at cap_n's post under "posting video clips" in the pitching forum. I believe he has given some suggestion on angles and he is willing to host the video on his server.

shermanreed,

I don't know your background, but assuming it's not as a former college or pro pitcher, I would definitely recommend not to self-diagnose. There is so much info out there..a little bit of knowledge is dangerous.

My son is also a LHP, just turned 16 yesterday. He's had years of training with former pros, college instructors, etc. His strike to walk ratio has improved dramatically through mechanics and balance. I certainly couldn't have taught him.

Remember, your son is a LEFTY! Protect him like you would a gold watch. Without proper mechanics and balance, his velocity will be limited. Find a qualified instructor asap.
