Looks like achieving more than 7 men's singles wins is impossible.
Mentioned on the live text feed on BBC Sport that a Fed defeat here would be the first time we had no Fed, Rafa, or Djok in the semis at Wimbledon since 2002
Inspired by that, I checked when the last time none of those three were in the semis of any of the Grand Slams - it was the 2004 French. 12 years ago!
Does Nadal winning 9 at the French not count?
No Fed, Djok, Rafa in the final of Wimbledon for the first time since 2002, and in any of the Grand slams since 2004!
Cilic/Nishikori 2014 US open final is just one off the top of my head. Too lazy to check for more...
