Walk up music, if you're not a baseball fan, is the short clip of a song that a baseball player chooses as they stride to the plate. It is usually used for professional baseball players and the music can be inspiring or intimidating. We hadn't seen walk up music used in a tee-ball game before, but if they do it like this kid, we want to see MORE of this. This could be the greatest walk up music song and dance routine in the history of baseball ANYWHERE on ANY LEVEL. Check out this kid's moves, and then he actually gets a hit! Even the mom videoing this can't keep it together watching the moves at the plate!
