I was there on Thursday/Friday/Saturday and I watched Rafa practice every single day. The practice court was always packed 30 minutes before his arrival. I was able to get a couple of great Rafa autographs for my collection but I managed to do that on Thursday and Friday. It was like a mob scene with people screaming and literally jumping on the backs of others to get a picture of Rafa or an autograph 
How do you find out where a player is practicing and when?
I vow I am going to do that this year.
