So what happens if Djokovic and Rune win 2-0 next matches
Sinner then has 2 wins and 4-3
Rune 2 wins and 5-2
Djokovic 2 wins and 5-3
In this scenario Sinner is actually out?
And Rune wins 2-1 then all 3 have 2 wins and 5-3 in sets, what then?
They do a three way between them where Sinner is 3-3, Rune 3-3 and Djokovic 3-3
How do they decide who goes through?
