Roger Federer admitted he struggled in the New York conditions after crashing out of the US Open to world number 55 John Millman. The 37-year-old Swiss was a huge favourite to progress to the quarter-finals and a clash with rival Novak Djokovic but, after taking the opening set, he went down 3-6 7-5 7-6 (9-7) 7-6 (7-3) in three hours 35 minutes.
It is the first time in his career that the five-time Flushing Meadows champion has lost to a player ranked outside of the top 50 in the tournament and it seemed as though the heat and humidity got to the legend.
Federer rarely complains about anything during his matches but appeared distracted and flustered for large periods of the contest, becoming vocal about crowd noise during some tense periods.
Afterwards, he revealed that it was not a pleasant experience and one that he was happy to complete.
“It was very hot and one of those nights where I felt I couldn’t get air,” he said. “I just struggled in the conditions and it was one of the first times it has happened to me.
“You just keep sweating and lose energy. At some point I was just happy the match was over.”
Australian Millman, who now faces two-time champion Djokovic in his first Grand Slam quarter-final on Wednesday, admitted he was in a state of shock after the best win of his career.
“I’m probably in a little bit of disbelief,” he said. “I have so much respect for Roger and everything he’s done for the game. He’s been a hero of mine.”
