Swiss tennis player Roger Federer was left out of the U.S. Open after the five-time tournament champion lost 3-6, 7-5, 7-6(7) and 7-6(3) to John Millman.
The Australian advanced to a quarter-final match where he will face Novak Djokovic, who beat Joao Sousa 6-3, 6-4, 6-3 to qualify for the quarter-finals of the tournament.
Sousa arrived in New York with seven consecutive defeats, but in the last Grand Slam tournament of the year seemed to regain his level.
But despite that, he was never a threat to the former world number one on a day when the heat was once again the protagonist. “I’m not 21 anymore, that was 10 years ago. I don’t feel old but at the same time the biological clock is not ticking in my favor,” said Djokovic.
“The heat was a hardship, it’s not easy to play in these conditions but you have to find a way to overcome it and win.
In another match of the day, Kei Nishikori beat Germany’s Philipp Kohlschreiber 6-3, 6-2 and 7-5 in a match in which the Japanese scored 29 winning shots.
In the top eight, Nishikori will play with Croatian Marin Cilic, who beat Belgian David Goffin 7-6, 6-2, 6-4.
