Roger Federer hit one of the most stunning winners of his career against Nick Kyrgios in the third round of the US Open.
The crucial game came at 3-all in the first set when Kyrgios had three straight chances to break Federer's serve and take a 4-3 lead but instead lost a nine-minute game.
Federer took advantage of a drop in focus from his opponent to secure a second consecutive break to increase his advantage at the start of the second set.

Kyrgios, seeded 30th, came into the match on the back of controversy surrounding the intervention of umpire Mohamed Lahyani during his four-set victory over Pierre-Hugues Herbert but began in encouraging fashion racing through his opening few service games.
"Almost unreal", said Kyrgios, who admired the bit of racquet wizardry with eyes wide open and mouth agape.
"The amusing thing about that shot was I didn't think about it until I hit it", he said. "Other big shots I remember, with Andy (Roddick), the counter-smash, and of course the between-the-legs here with Novak (Djokovic)".

The Aussie star took to social media to congratulate the 37-year-old and predicted Federer could well be on his way to the 21st Grand Slam of his career. Kohlschreiber now meets 2014 runner-up Kei Nishikori, who got past No. 13 Diego Schwartzman 6-4, 6-4, 5-7, 6-1.
"He's the best that's played the game, in my opinion", said Millman, who practised with Federer ahead of the grass-court portion of this season. All the pressure was off him. I think there is a lot more to be done and there is a lot more to be, I mean, explored. "When he gets in front, there's not much you can do".
Kyrgios started as the entertainer but it was now Federer putting on the show, the 20-times major victor flicking a sublime backhand victor then rifling a forehand cross court to charge to 5-0 before seizing a two-sets-to-love lead with his 10th ace.
