Its ALL on the adults. The critiques, comments, congratulations, etc...etc. from coaches, and foremost, the parents will be the greatest things from that moment. The player lives for those moments and feeds on them... it's always gonna be awesome sink or swim because they are incredible players. That incredible athlete may or may not cry whether they win or lose, but if the adults aren't properly reassuring then the moment could be a downhill ride for the rest of their softball lives with a simple, "gee thanks", and all that encompasses from a pre-teen or know-it-all teenager.
Disclaimer: A proper positive reassuring statement can receive the same "gee thanks" response but you'll know the difference when they truly are thankful.
