Alcaraz, Sabalenka romp into last 16 at US Open

World number one Carlos Alcaraz surged into the last 16 of the US Open on Saturday as second-seeded Aryna Sabalenka advanced safely in the women's draw.

Alcaraz, looking to become the first man to successfully defend the title since Roger Federer in 2008, polished off British 26th seed Dan Evans 6-2, 6-3, 4-6, 6-3 in 3hr 11min.

"He's a tricky opponent," Alcaraz said. "I think when we play each other it's a show on the court. We made great points, great shots, a lot of different kinds of situations."

Alcaraz, who will surrender his world number one ranking to Novak Djokovic at the end of this tournament, admitted he was motivated by matching Federer in defending his crown.

"Obviously defending the title is a goal for me," he said. "I'm looking for that. Nobody's done it here since Roger so I'd love to be part of tournament history with him."

Alcaraz's last-16 opponent Arnaldi, meanwhile, advanced after upsetting 16th-seeded Briton Cameron Norrie, winning 6-3, 6-4, 6-3 in just under two hours.

Arnaldi, 22, had never played in the main draw of a Grand Slam before this season, with a brief run to the second round at Roland Garros his best performance in a major championship.

There was better luck for another member of Britain's US Open contingent elsewhere though, with Jack
