I just like the kids all trying to constantly knock the mud off of their shoes in that video. That is one WET infield.
My 10 YO DD hates to strike out. Hates it more than anything. She has a good swing when she goes all out but is so worried about putting the bat on the ball that that's what happens. She puts it in play for an easy out. I've been emphasizing to her to be more aggressive early on in the count, you can't get hard hits if you don't swing the bat hard.
My point? You can't get too worked up about strike outs. They happen and they happen to good hitters. Worrying about them leads to a vicious cycle of bad swing mechanics.
With you!!! I say swing away hard ... twice, two out of three ain't bad... but if don't get it, Plan B....watch as many as you can, so you'll be ready for your next two swings.
