Will this girl think I am creepy or weird?

There is this girl that is an athlete and comes in to the training room where I work a lot, and I think she is really cute, but have never talked to her. I added her on facebook a week ago, but I removed her today so I wouldnt be sketch. Meanwhile I think I caught her looking at me today with a look like "that guy added me on facebook," which is exactly why I removed her, so It wouldnt seem creepy, Although I doubt she has noticed I removed her. But I would like to talk to her, and maybe ask her out but I absolutely have NO game with girls. She is pretty but I feel like I have a shot with her, since we are both involved in our school's athletics.
