High School Baseball?

I have never been involved in high school athletics and I would like to play high school baseball. What can I expect going into conditioning and tryouts? My problem is I can't do push ups and the baseball coach is my gym teacher and he knows when it comes to push up exams, I struggle. Is that going to keep me from having a chance at making the baseball team, even if I have the ability to play like the other kids. Coach knows I have a good work ethic as I participated and dressed out everyday in Gym and had All A's in Gym cl. Thanks for your answers as I have been really worrying.
