Roger Federer cruised into the US Open quarter-finals, thrashing 15th seed David Goffin 6-6 6-2 6-0 in just 78 minutes.
The Swiss five-time champion fell a break down early in the first set but then won six games in a row to establish control in the fourth-round match.
Federer, 38, hit 34 winners while Belgian Goffin could only manage eight.
He will face Grigor Dimitrov or Alex de Minaur in the last eight.
"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," said Federer.
