The 2019 ATP Finals champion, Stefanos Tsitsipas, was given a wake-up call by Andrey Rublev in his first match at this year's tournament but promised to improve.
He went down 6-4, 6-4 in 90 minutes to the Russian World Number 5 who put on a serving masterclass, winning 90% of points on his first serve.
However, thanks to the unique Round Robin format of this tournament, all is not lost for the Greek. 'It is a format that most players are not familiar with because we don’t get to play it very often. I like it because it gives me chances and I can improve and get better match by match,' he said in his post-match press conference. 'I am excited. I still want to play good tennis. Despite the loss today I feel I will get more chances. I want to step it up and play better tennis next time.”
The victory means Rublev levels his H2H with Tsitsipas with four victories apiece.
Next up for the Greek is Casper Ruud, who gave Novak Djokovic a stern test before eventually losing in straight sets. Djokovic currently leads the Green Group with Rublev in second place. They square off for the first time ever in the afternoon match on Day Four.
