When I was 17, I messaged the media/marketing/PR guy at the New Britain Rock Cats (Minor League), he responded with questions verifying if I was actually something more than a crazed fan. After that was out of the way, the team agreed to let me shoot a couple of games. It never hurts to ask, the worst they will say is no! Make sure you have a portfolio/website to send them for basic verification.
