This was Keys' first quarterfinal appearance.
"Venus last night said it very well that the younger ones were looking at Lindsay (Davenport), Jennifer (Capriati), and Serena and Venus", she said.
The 25-year-old Vandeweghe, a niece of former National Basketball Association player and current league executive Kiki Vandeweghe, certainly has her career pointed the right way.
The last time all four U.S. Open semifinalists were American was in 1981, when the players were Tracy Austin, Chris Evert, Martina Navratilova and Barbara Potter. She has won twice previously at Flushing Meadows, in 2000 and 2001. Vandeweghe, who was the junior champion in NY in 2008, reached a Grand Slam semifinal for the first time ever earlier this year at the Australian Open.
The typically reserved 25-year-old even saw her temper boil over during her match on Wednesday when she threw her racquet violently to the court in disgust after hitting a forehand long to hand the first set to Vandeweghe. "I'm really proud of myself for digging deep and figuring that out tonight". Vandeweghe is doing a much better job of putting mistakes and errors behind her and focusing on the next point, which is the reason for his breakout performances this season.
Pliskova's reign lasted eight weeks but she never shied away from admitting she felt the extra pressure as the world number one.
"The goal is the Australian Open, but that will of course depend on many things, including how Serena recovers", said her coach, Patrick Mouratoglou.More news: Mayweather chooses 'right dance partner' for final fight
"I think it was just good for me to get a feel for what it's like playing on a big stage, playing on Ashe", Brady said, "Next time I play on it, I'll know what to expect".
Pliskova did not exactly heap praise on her opponent afterward.
"I'm really happy with how I was able to close out the match in the fashion that I did", she said.
"She's a great player, a great person". They all motivated me to do better and to be the next American coming up.
Pliskova, who is from the Czech Republic, also offered this assessment of Vandeweghe: "She just (has) one plan, so either it's working or it's not". Vandeweghe did it with a controlled, precise, powerful effort that portends well, especially since she will be getting No. 1 ranked Karolina Pliskova in the next round. She has dreamed of triumph at the U.S. Open since winning the girls' title as a wild card at 16 without dropping a set.
"I mean, it means the world to me to make the quarterfinals". "And I'm still going to practice, work out and try to improve every day". I played her last time in Stuttgart, I think, so it was clay, a little bit different story.
