John Millman has beaten Roger Federer at the US Open.
Millman defeated the number two seed 3-6, 7-5, 7-6 (7), 7-6 (3) in a gruelling three-and-a-half hour match to reach his first ever quarter final in a Slam.
He becomes the second ever Aussie to defeat Federer in a Grand Slam, following Pat Rafter a whopping 19 years ago.
"(I'm) probably in a little bit of disbelief," he said after the match.
"I have so much respect for Roger and everything he's done for the game.
"I'll take it!"
