"I think it's great" to have such numbers, Coco Vandeweghe said, "in our American Grand Slam".
She saved the only two break points she faced, and converted on six break points on Brady's serve for a almost flawless performance.
Federer was trying to keep alive his hopes of the long-awaited first match-up at the US Open with Nadal when he brought an 11-0 record against No 33 seed Philipp Kohlschreiber into their night match-up.
"I would say the first match was okay".
Keys overcame a 4-2 deficit in the third to win the last four games of the match to reach her first US Open quarterfinal. She went on dominating Brady with her aggressive style of play.
The onslaught was too much for the unseeded Dolgopolov, who was never comfortable enough to unleash his unconventional game that features unexpected drop shots and bold net approaches. I think it will be an easier match to the tune of 6-2 6-4.

CoCo Vandeweghe is on her way to the U.S. Open quarterfinals. "I'm really proud of myself for digging deep and figuring that out". "It was good for me to get a feel for what it's like playing on a big stage, playing on Ashe". She had lost the first round and had to fight off a match ball in the second before making a rally to defeat Zhang Shuai 3-6, 7-5, 6-4.
This time, she raced to a 4-0 lead against an obviously nervous opponent, then won the second set in even more lopsided fashion.
It only took 25 minutes for Pliskova to take the opening set as errors made an unwelcome early appearance in Brady's game.
Pliskova, for her part, had put together good results on all three surfaces this season: the semis at Indian Wells, Miami, Cincinnati and Roland Garros, plus the Eastbourne title. "Next time I play on it, I'll know what to expect", said Brady.
Former champion Juan Martin del Potro, the No 24 seed, faced sixth-seeded Dominic Thiem, with the victor getting Federer if the five-time champion can improve his 31-1 record in night matches at Arthur Ashe Stadium. Vandeweghe will come out firing and with the crowd's support, she stands a chance to dethrone last year's finalist. I played her last time in Stuttgart, I think, so it was clay, a little bit different story.
Seven matches later, the Estonian will face either fourth seed Elina Svitolina or Madison Keys in the last eight. Sloane Stephens will mark her third, and Vandeweghe her fourth.
As the lowly Americans from the overmatched country impress even when losing decisively, someone from that exceptional Williams family, Venus, will grace her 39th Grand Slam quarterfinal.
