Daniil Medvedev dropped just four games as he breezed past Nuno Borges to secure his place in the US Open quarter-finals.

Russia’s Medvedev, champion in New York three years ago, was barely troubled by the Portuguese in a 6-0 6-1 6-3 win.

Medvedev is the only former US Open champion left in the draw in New York, and the only Grand Slam singles champion other than Jannik Sinner.

He could potentially face world number one Sinner – who beat him from two sets down in the Australian Open final in January – next.

It is the fifth time in the past six years that Medvedev has reached the last eight at the US Open.

Medvedev was interviewed on court afterwards by Nick Kyrgios, who was the last player to beat him before the quarter-final stage.

“The last time I lost in the fourth round was against you, right? Good memories,” the 28-year-old joked.

“I try to work hard. Sometimes I do, sometimes I don’t.

“I have the mentality that if the other guy practises more than me, I have less chances to win, and I want to win all the time.”
