Image source, Getty ImagesBritain's Dan Evans, speaking to Sky Sports after beating Russian 23rd seed Karen Khachanov in the longest US Open match in history: “I haven't played a bunch of tennis this year, I just tried to keep fighting - at 4-0 I thought I was out, I felt a little sorryfor myself, got myself going and didn’t want to go out another Slam without afight and a whimper. I could see he was struggling a bit and tried to grab agame at a time.
“I’ve got a bad headache now."
On his year so far: “I’ve had a horrible year. I knew I had put the work in but not enoughbecause I was a bit hurt. Like to think I got a bit of luck at the end, nearlyblew it at the end but I’m really happy. It was a hell of the match. I justwant to go to bed."
On the crowds: “It was amazing at 4-2, it really started to get going. They sort of sensed it, I don’t know how many Brits were there, but It seemed like the whole place wanted me to win. I don't think that has ever happened before. It really helped. I played pretty good, great last point and here we are."

Former British number one on BBC Radio 5 Sports Extra and BBC SoundsIt is just extraordinary to witness this because who would ever have given Dan Evans a chance at 4-0 down?
If you listen to the crowd, they are very much behind Evans. Quite a lot of them are on their feet.
He was down and out in this match, he literally couldn't put one foot in front of the other and now he is looking energised.

Lajovic 3-6 6-3 3-6 1-6 Medvedev
Russian fifth seed Daniil Medvedev speaking after beating Dusan Lajovic: "In the second set he played an amazing level, I don't think you can play better than he did. I first off changed my clothes to be fresh for the third set. I was really tired at the end of the second set. I played aggressive, didn't face a break point afterwards and just played a tiny bit better. He lowered his level a little bit and happy to win."
On his reactions during the match: "He played some unreal points where I didn't know what I had to do to win a point. I tried to play even better and so I was really happy when I managed to do it, that's why I yelled 'come on'. It depend on the match and depends on the moment."
On coming back to the US Open: "Every year is different and if not better and better. First coming here I just try to win one match but now coming here is the best place in the world for me to play. I love it here, my favourite tournament in the world. Honestly, the only goal when I come here is to win. There are tough opponents but the only goal is to win so hopefully you can help me, guys."
