Rafael Nadal recovered to beat Stefanos Tsitsipas 6-7 (4/7), 6-4, 7-5 on Friday but faces an anxious wait to find out whether he will play Roger Federer in the last four at the ATP Finals.
The Spanish top seed is pinning his hopes on Daniil Medvedev beating defending champion Alexander Zverev in the evening match in Group Andre Agassi in London.
Nadal’s efforts will count for nothing unless Medvedev, who now has nothing to play for, beats Zverev. A win for the German would send Nadal home.
“I don’t know if I will see you tomorrow because it depends on the match of this evening but I did all the things that I could today,” said Nadal.
“I fought until the end two days ago and today, so if I am able to play in front of you tomorrow against Roger it will be a huge honour. If not, I really hope to see you next year.”
