Fantastic Federer destroys Goffin and closes in on Djokovic battle
Roger Federer laid down a marker by dismantling David Goffin to reach the quarter-finals of the US Open.
The third seed dropped just four games, winning the last nine on the trot, for a brutal 6-2 6-2 6-0 victory in just an hour and 21 minutes.
If Britain's Dan Evans was feeling bad about the manner of his third-round defeat to Federer, he can surely take some comfort from the fact he won one more game than Goffin, the 15th seed.
Federer had looked susceptible in his opening two matches, dropping a set in both, but now he is cruising through the gears, motoring towards what looks likely to be another semi-final against Novak Djokovic.
Goffin, who actually broke Federer's serve early in the first set, won just seven points in the third, the Swiss finishing him off with a stunning backhand pass down the line.
Federer, looking for a 21st grand slam title, said: "David didn't have his best day, he was struggling. I was down in the score early and I was getting to down on myself, but when I got up a break I felt he wasn't playing the same way I know he can play. It was a great day and I'm very happy. It was great. David didn't have his best day either, he was struggling. I was down on the score early so had to come back mentally."
Federer will face Bulgarian Grigor Dimitrov in the last eight.
Dimitrov, a former world number three whose ranking has dropped to 78, beat Australian Alex de Minaur 7-5 6-3 6-4.
The third seed had dropped the first sets in both of his opening two matches, but played with a swagger when he beat British number two Dan Evans in 80 minutes in the last round.
That form continued against Goffin, with the Belgian winning less than half Federer's total of 83 with 39.
Federer booked his place in the quarter-finals for the 13th time in New York with a stunning passing shot down the line.
Should Federer make it to the last day for the first time since his defeat by Djokovic in 2015, he could come up against Spanish second seed Rafael Nadal for the first time at the US Open in the final. Nadal moved ominously into the last 16 with a straight-sets win over Chung Hyeon.
The Spanish second seed made light work of South Korean qualifier Chung, winning 6-3 6-4 6-2 - a victory which took him a minute shy of two hours.
The draw has certainly been kind to Nadal with both his great rivals on the other side, while second-round opponent Thanasi Kokkinakis was forced to withdraw through injury.
It meant that while Chung, a former Australian Open semi-finalist who has slipped to 170 in the world due to injuries, had already spent 11 hours on court this week, Nadal had spent just two.
