Dan Evans won the longest match in US Open history last night, taking five hours and 35 minutes to defeat world No.22 Karen Khachanov.

British star Evans suffered cramp during the effort and had to play through the pain barrier to reach the next round.

He then declared: “I don't really want to do that again!

“It was just a crazy, crazy match. It's one I'll remember obviously forever. It was sort of who could last the longest in the end. I was hurting all over really.

“It's the longest I've ever been on a court. I don't think I've played that long, five hours, in a day ever in two sessions, never mind in one! I was actually thinking that on the court. I've never practised for two hours, two hours. It's normally an hour and a half."
