I gave myself a break-and watched Doctors. 
Keith has not beaten Rafa since the Rio Olympics (and that was a hard court)- but to be fair, there haven't been many opportunities, as both have been out injured. Keith in particular has struggled the last year or so.
I'm wondering who can beat Djok though.
Maybe Fed and Rafa will both be on Chatrier- like yesterday? I really hope Stan can do it. He is the last player to beat Fed at RG, after all.
