Petra Kvitova was the latest big name to exit the US Open women’s draw after she fell to Serbian qualifier Aleksandra Krunic 64 64 on Saturday. The No. 3 seed and defending Wimbledon champion fought back from a break down in the second set to level the score at 4-4 but that was the last game she was to win as the 21-year-old world No. 145, who had never won a Grand Slam match before this week, broke again and then served out the match.
"It was an honour for me to be on the same court as Petra, who is a great champion," said Krunic. "Going to play against such a champion meant to stay on the court as long as possible. Of course, I didn't expect to win. Of course, I hoped to. I'm very happy."
Krunic will face Victoria Azarenka in the 4th round after the Belarusian, who seems to be showing signs of returning to form after battling with an injury in 2014, defeated Elena Vesnina 61 61.
No. 15 seed Carla Suarez Navarro was another casualty on day six at Flushing Meadows. She just lost a tight first set with Kaia Kanepi before being bagelled by the Estonian in the second. Kanepi will face world No. 1 and defending champion Serena Williams in the last 16 after the American saw off compatriot Varvara Lepchenko 63 63 in her 3rd round match on Arthur Ashe.
Novak Djokovic needed just one hour 25 minutes to dispatch of Sam Querrey, who won just seven games in his straight set loss to the Serbian. The world No. 1 will meet Philipp Kohlschreiber in the round of 16 on Monday after the German defeated John Isner in the 3rd round the third straight year.
Milos Raonic’s campaign for a first Grand Slam title continued after he squeezed past Victor Estrella Burgos 76 76 76, to end the Dominican Republic player’s ground-breaking US Open run. Raonic’s compatriot Eugenie Bouchard also progressed to the next stage after recording a 62 67 64 victory over Barbora Zahlavova Strycova in the night session.
"I did way more unforced errors than I expected," said Bouchard. "To just give away so many free points is really frustrating. I realised in the third I can still stay with her, I don't have to go for crazy shots all the time. I was a bit too impatient in the second set."
Andy Murray started his match against Russia’s Andrey Kuznetsov well, but a dip in concentration in the third set saw his victory take four sets to complete. He will play Jo-Wilfried Tsonga in his next match after the Frenchman defeated Pablo Carreno Busta 64 64 64. Stan Wawrinka moved through to the next round of the draw without having to step on court after his opponent, Slovenia’s Blaz Kavcic, withdrew with a right foot injury.
