Casper Ruud, the fifth seed, outlived Tommy Paul in five sets to secure his place in the fourth round of the US Open.
Norway’s Ruud, who lost the French Open final to Rafael Nadal earlier this year, battled the American 7-6 (7-3) 6-7 (5-7) 7-6 (7-2) , 5: 7, 6: 0 through in four hours and 23 minutes.
Ruud is one of four players aiming to become world number one by the end of the tournament.
He will play the French Lucky Loser Corentin Moutet next.
Moutet passed Argentina’s Pedro Cachin 6-3, 4-6, 6-2, 7-5.
Ruud, defending champion Daniil Medvedev, Australian Open and French Open winner Nadal and rising star Carlos Alcaraz could all top the men’s rankings after the tournament.
Medvedev, who currently holds the top spot, meets Chinese qualifier Wu Yibing in the Arthur Ashe Night Session.
Nick Kyrgios is also in action while 11th seed Matteo Berrettini ended Andy Murray’s hopes earlier on Friday.
