My chance of getting into Harvey Mudd?

I LOVE math and science. I have a 4.00 and will have only taken 3 AP Courses by the time I graduate high school. I have been in a varsity sport for 3 years, and this year I will be team captain. I am not involved in many clubs/volunteer. And my SAT scores are not the best... What are my chances of getting into this selective school?
