I have seen a few College players diving head first to 1st base and I never understood why? Logic tells me that running thru is faster. I can understand diving back to avoid a tag, but not on the initial run to 1st. I'm an assistant coach for my daughters 12u team and the head coach wants our girls to learn sliding head first to 1st base to beat the throw down. In my opinion it's unsafe and slower. How am I wrong?
