Video - When Federer defies the laws of tennis... and leaves Kyrgios incredulous
US Open 2018. Federer hits a shot only he has the secret to, literally going around the net. Nick Kyrgios's reaction, a mix of admiration and amazement, captures the moment: sheer artistry.
In 2018, Roger Federer remains at the peak of his abilities, having won the Australian Open and reclaiming the world number one ranking for several weeks.
The Swiss player breezes through his first two rounds at the US Open and then faces Nick Kyrgios. He overcomes this challenge without trouble (6-3, 6-1, 7-5) with a shot that captivated the world.
On a cross-court drop shot from the Australian, Federer dashes towards the ball, manages to avoid a second bounce in the nick of time, and spectacularly sends it back by going around the net.
A sublime shot that left Kyrgios speechless and brought a smile to the Swiss champion's face.
US Open 
You're just diabolical. So poor.
