How do you get a hockey guy interested?

Okay so Im 16. There is this hockey guy that I think is really cute. But we go to a big school and I don't have any cles with him. So I don't really know him and as far as I know he doesn't know me. We are both jr. His little sister is on the badminton team with me so I kinda have that but they are by no means close. I have been to his games and I saw him looking at me before the game and I glanced up and we kinda just looked at each other for a little bit. So what do i do? Guys Please help!!
