WATCH: The incredible Roger Federer shot that left Nick Kyrgios stunned

Roger Federer's third round clash with Nick Kyrgios at the US Open did not disappoint on Saturday.

There was Kyrgios imitating Federer's serve, some ruthless efficiency from the Swiss, and the Australian melting down against his own box.

However the undoubted highlight of the match was this absurd shot from Federer.

There are no words for Federer's brilliance.

Kyrios' reaction really says it all.
