Madison Keys becomes fourth American to reach US Open quarter-finals

Karolina Pliskova's eight-week reign as world No.1 is over.

"But now I'm afraid to, like, play in the sun because I haven't done it in two weeks, so..." If they got that far, it was victor takes all: the No1 ranking. That distinction will belong to Wimbledon champion Garbine Muguruza of Spain.

On paper, Pliskova's first hurdle to reach the quarter-finals was significantly easier than Svitolina's.

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.

Stephens advanced on Tuesday with a gritty victory over 16th seeded Anastasija Sevastova which was followed by 37-year-old Venus Williams outlasting 13th seed Petra Kvitova.

Vandeweghe won 81 percent of her first-serve points to keep Pliskova on the defensive, but the former was thrilled with how she reacted to the latter's serves.

"So this feels really good".

The result was a real disappointment for Svitolina, who despite her excellent season on the WTA Tour has only made one grand slam quarter-final. "Of course, going out there I was a bit nervous", Brady said.

All smiles: CoCo Vandeweghe after defeating Pliskova.

No. 4 seed Elina Svitolina has come back to take the second set and force 15th-seeded Madison Keys to a third at the U.S. Open. "On top of coming back after having a big win the other night then all of a sudden being in a match where you're supposed to win". It was just a one-sided affair in the tie-break as Keys was just hitting the ball so cleanly, blasting winners past her higher-ranked opponent to clinch the first set after just 45 minutes of play.

"Just happy that this tournament is over now", she added with a smile.

Next up is American Vandeweghe, who registered a 6-4 7-6 (7-2) win over Lucie Safarova, and Pliskova knows she faces a tough battle to reach the last four.

The 22-year-old American can expect great support from the NY crowd as she takes on Kanepi, who is into her second U.S. Open quarter-final having reached the last eight in 2010.

The 22-year-old from Rock Island will now go the semifinals where she'll be up against American, CoCo Vandeweghe. And then came a run to match her best Slam performance from the 2015 Australian Open.

A USA women's victor became guaranteed at the US Open on Wednesday when CoCo Vandeweghe and Madison Keys completed an all-American semifinals at the US Open.

Now she finds herself bettwe able to adapt in matches and dismiss frustrations. "We have so many Americans to talk about in the last days of the US Open".
