With the US playing 3 days of 1st round, there would also be the possibility that Rafa/PEHK would play Saturday Tailgate day. Sadly, they would likely have that match on Ashe, and while I have a Saturday Ashe ticket, I really don't like watching matches in there. That's why I would much prefer a Kohli/Simon Friday match. Incidentally, Simon was one half of my all time favorite in person mens match in all my years of going to matches, so I'd be very happy to see the two of them play.
