Well I want to see him beat Tsitsipas to clinch another 4 weeks at #1. Even if he is still eliminated. That gets him 210.
ATP Cup has 775 for undefeated champ. It is still very close at the top there with Djokovic. Every point and every match means something. YEC, ATP Cup, AO, all very tenuous situations. Of course if Djoker loses early in AO, then Rafa can hold it arguably till Wimbledon cause he can make up a lot on clay after he did not win MC, Barca, or Madrid.
Nightmare scenario: Fed wins YEC and wins AO. Now he has 9310. Rafa loses to Tsitsipas in London, and loses in SF in AO. Now Rafa has 9305. Not only Fed gets to 21 slams, now he also gets back to #1 and extends beyond 310!!!! With Fed not playing ATP Cup, those extra points might be the only thing protecting Rafa or Nole from losing #1 to 500 year old Federer
So anything can happen, there is a lot at stake not just rest of this week but very early in the season next year. And if it is neck and neck, we may see Fed, Nadal, and Djokovic all bouncing back and forth between 1,2,3 all year long, this guy gets a week, that guy gets a week, etc., and the history and narratives shifting with them. Very exciting tennis times as a fan.
But let's focus on Tsitsipas first.
