Rafael Nadal to face Andrey Rublev in US Open quarters

Nadal bounced back from a set and break down to outplay Daniel 4-6, 6-3, 6-2, 6-2 in an exhilarating second-round clash under the lights on the Arthur Ashe Stadium. "After that, the match was completely different".

"Now I have the opportunity to compete again, to try to do it well".

Juan Martin del Potro, a countryman of Mayer, continued his impressive play by recording his third straight-sets victory and setting up a fourth-round match against sixth-seeded Dominic Thiem.

In his post-match press conference, he was once again asked about the Tennis Integrity Unit's (TIU) investigation into a match between him and Thiago Monteiro at the Winston-Salem Open, a match where Monteiro recorded his first ever ATP Tour win on a hard court.

- Brady served six aces and hit 46 winners, but will need to improve on her 52 unforced errors if she is to give herself a chance of reaching the quarter-finals at the expense of world number one Pliskova.

It was the Brazilian's first ATP hardcourt triumph and came without Dolgolpolov managing a break-point chance, a poor showing he blamed on heavy training for the US Open that left him drained and exhausted. "I know I can not play very well always, and not the whole match". I changed more forehands down the line, hitting some good backhands later. Thiem served for the match at 5-3, but got broken. He's in a very good form no and also the previous weeks and month, so it was a tough match.

"I think the best thing is I had a lot of moments to be very frustrated in the match, and I was not".

Thiem was equally impressive.

Keys now faces Estonia's Kaia Kanepi, who beat Daria Kasatkina 6-4, 6-4 to become the first qualifier in 36 years to reach the U.S. Open women's quarterfinals.

No. 20 CoCo Vandeweghe beat Lucie Safarova 6-4, 7-6 (2) earlier Monday, while Venus Williams and Sloane Stephens advanced Sunday. I don't really like to play against him. "I hope we can produce another good one".

"For sure, by far, the best performance by me".

As for what effect the whole episode has had on him, Dolgopolov said: "Not much".

When it was over, del Potro raised both arms overhead and threw his head back, enjoying the fans' adulation, then crossed himself.

Ninth-seeded David Goffin of Belgium advanced to the fourth round when 18th-seed Gael Monfils of France retired because of injury with Goffin leading 7-5, 5-1.

Nadal played his best match of the tournament to beat Alexandr Dolgopolov 6-2 6-4 6-1 while 19-year-old Russian Rublev defeated an injured David Goffin to become the youngest men's quarter-finalist in NY since Andy Roddick in 2001.

Goffin's next match will be against 19-year-old Andrey Rublev of Russian Federation, who defeated Damir Dzumhur of Bosnia and Herzegovina 6-4, 6-4, 5-7, 6-4.

Third-seeded Roger Federer was slated to play his third round match on Saturday night.
