US Open 2024 results: Dan Evans backs up marathon win; Katie Boulter stunned but Jack Draper through

Evans said he needed to remain “mentally” strong to reach the third round following Tuesday’s epic endurance test against 23rd seed Khachanov.

“I knew it was going to be difficult the longer that it went on,” said Evans.

“My big goal was to be big mentally today. Obviously I’m tired and when you’re tired you can make poor mistakes but I didn’t do that.

“I came forward great, made him pass a lot and was aggressive. That helped me mentally and physically.”

Prior to his victory over Navone, Evans had failed to win two successive matches on the ATP Tour this year.

The world number 184 found himself 3-0 down in the first set before recovering, winning six of the next seven games to take control of the match.

He overturned an early break in the second set before breaking twice more, while he held off a late surge by Navone in the third.

Evans celebrated with fans as his opponent fired a forehand long on the second match point after two hours 37 minutes.

“It’s been different, but it was important to win today,” he said. “The record and stuff is obviously great but I’m here to win.”

He will play Australian 10th seed Alex de Minaur, who defeated Finland’s Otto Virtanen 7-5 6-1 7-6 (7-3), in the third round.
