普通の高校球児がプロ野球選手になる為にした、3つの方法

Thank you for watching today's video! Today's video was a pitching lesson where I taught you the pitching form that really changed my game. What did you think? There are three key points! Left hand height, right knee, and stride length. It's really simple, so please pay a little attention to it when pitching! And then, give it a try! #Baseball #Maeken #Pitching
