For those who follow this closely, can you help me get a good sense of who might be playing this weekend including monday at the US Open? I'm interested in seeing the top 15 men on any court, but haven't really got an idea of who might play when. I know Rafa, Murray, Del Potro are playing today so wont play tomorrow, but could they play Sunday or Monday? I heard Roger is playing Saturday. What about the rest of top 15 guys? Any approximate guesses would be helpful thanks!
