First All Star game of the year 10-0 top of the third for the win. Having a blast coaching these guys.
So a buddy of mine from college runs these baseball tournaments, and as an ex-collegiate/semi-pro player and lover of the game, I help him out (the kids are like 13-16).
If there's one thing that I would do as a coach for these kids is to tell them to keep their weight back. I was out at a tournament a few weeks ago and consistently these kids were lunging at pitches, swinging all arms, topping the ball for weak little grounders.
Stay back, get that front foot down and get that action going and transfer your weight from back, through the ball, to front.
If you can teach kids that, they will be set for awhile.
