If a girl invites you to her game, how do you know if she's being friendly or interested?

At my school, I hang around the athlete crowd. It makes sense I gravitate towards them, since I'm athletic myself and enjoy playing sports. Anyway, sometimes I'm talking to a girl I'm attracted to, and she says "You should come to our game!" and gives you info on when and where. So being the person that I am, many times I go to support them, and the girl who invited me. But I never know if she's just trying to get people to come or is interested and wants me there to support her.

A couple times, I've attended games, cheered the girl and the team on, and then met her afterward, and she acts shocked when I ask her out down the line. Another time, the girl was weirded out that I came, and I was confused because she invited me. So how do I know if she's just being friendly or is legitimately interested?
