We use Ninth Inning for my rising 15U son. He has been with Mike Bohanna this season and is having a fantastic year. BA is up considerably as his power has returned very nicely.
He works out of Medlock park. In addition to the physical skills of hitting, he is very good with the mental side. My son put one over a 385 foot fence with BBCOR last week, so he must be doing something right.
Justin Pannell has been helping my son with hitting lessons. You can find his listing on craigslist in Athens--search for batting lessons. He also will do pitching lessons. jpannell8@gmail.com
