Open Tennis Championships continues as she defeated the No. 1-ranked Karolina Pliskova, 7 (7)-6 (4), 6-3, to reach the semifinals.
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.
The 15th seed was just invincible on her serve throughout the whole encounter, clinching 79 percent of points behind her powerful first serve and losing just a mere six points off her second serve. Keys has also combined for 98 winners in her last three matches, proving she controls when the point is going to end most of the time.
"I'm going to have to serve really well", she said.
San Diegan Coco Vandeweghe's impressive run at the U.S.
Awaiting her is 20th seed CoCo Vandeweghe, who made the last eight for the first time by beating Lucie Safarova of the Czech Republic 6-4, 7-6 (7/2).
Unlike Williams vs. Stephens, this all-American semifinal gives us more history to glean from. "It has been a really great ride".
Kvitova eliminated Spanish third seed and two-time Slam victor Garbine Muguruza 7-6 (7/3), 6-3 while Williams beat 35th-ranked Spaniard Carla Suarez Navarro 6-3, 3-6, 6-1.
This is the second time Vandeweghe has defeated the reigning No. 1-ranked player in the world this year.
"Obviously before or when I started playing again at Wimbledon and D.C., I didn't expect much", Stephens said this week, per Sports Illustrated's Jamie Lisanti. "I was confident. I was feeling it". She was terrific against Kanepi, who sat with a white towel over her head during changeovers and dropped to 0-6 in Grand Slam quarterfinals. In the victory, Keys won 79 percent of her first serve points and 60 percent of her second serve points. She lost at that stage at Wimbledon in July, after making it to the semifinals at the Australian Open in January. "I'm thankful for the opportunity". I had to learn tactics, I had to learn pattern plays.
Sharapova is expected to jump from 146th to around 100th in the world rankings.
Remarkably, ninth seed Venus was part of that American quintet of Lindsay Davenport, Jennifer Capriati, Monica Seles and sister Serena 15 years ago and is aiming for a first title at Flushing Meadows since 2001.
Madison Keys beat Elina Svitolina at the U.S. Open.
Needless to say, their one meeting doesn't exactly stand out in Williams' mind. "I'm just so happy to be here". "I don't have words to describe". "I was very overwhelmed by the moment and I wasn't able to get myself together in order to play correctly". I don't really know. But she played confidently on Wednesday against Pliskova, who will lose her No. 1 ranking to Spain's Garbine Muguruza when the new rankings are issued next week.
