US Open 2018: Unseeded John Millman Upsets Roger Federer, Takes On Novak Djokovic In Quarter-final

Roger Federer's bid to win his sixth title at Flushing Meadow this season is no longer in view after John Millman stopped him from reaching the quarter-final.
It was stunning how the unseeded world number 55 eliminated Federer after dropping the opener, but soon made incredible improvements and fought through three consecutive tie breaks, coming out as the winner in four sets by 3-6, 7-5, 7-6(7), 7-6(3).
Federer sudden drop in tenacity caused him to commit 77 unforced errors and 10 doubled faulting, consequentially leading to his shock exit in third round, and his first defeat to an unseeded player with world ranking lower than 50th at the tournament in his 17 appearances.
It amazes the Aussie who won his second career ATP FedEx match with the Swiss saying "I'm probably in a little of disbelief. I have so much respect for Roger and everything he's done for the game. He's been a hero of mine."
However, Millman has a tough match ahead of him as he is booked to face former world champion Novak Djokovic in the quarter-final.
