Rohan Bopanna's sputtering US Open campaign finally ended today while Sania Mirza and partner Barbora Strycova moved into the quarters of the doubles event. Juan Martin del Potro's dream run extended into the quarters, while Serena Williams and Andy Murray also made it through to the quarters.
Sania Mirza and her partner Barbora Strycova came into the US Open on the back of a very short campaign after Mirza had split from Martina Hingis. The pair had won the Cincinnati Open against Hingis and her partner, and have continued their good run at the Flushing Meadows.
The seventh seeds advanced into the quarters of the women's event defeating the unseeded American-Japanese pair of Nicole Gibbs and Nao Hibino 6-4,7-5.
Meanwhile, Rohan Bopanna, who had earlier crashed out of the men's doubles event was ousted of the mixed doubles event as well today. Bopanna and his Canadian partner Gabriela Dabrowski went down in the quarter-finals of the mixed doubles 6-1, 2-6, 8-10 to Robert Farah of Columbia and Germany`s Anna-Lena Groenefeld in 58 minutes.
Juan Martin del Potro's dream run continued today as challenger Dominic Thiem withdrew from the match after suffering a knee injury. The Argentinian, who was ranked below 1000 until months back, began the match with both opponents evenly matched until 3-3. Then del Potro ran away with the first set to win it 6-3. After the set, Thiem received some medical attention for his knee but withdrew soon after sending the former US Open champion into the quarterfinal to face Stan Wawrinka.
"You never want to win a match like this. I wish Dominic a quick recovery as he has a great future," said 27-year-old del Potro.
Stan Wawrinka appeared set for an easy win over Illya Marchenko after he won the first two sets 6-4, 6-1. Marchenko, as well appeared to be suffering from a knee injury as he received attention on court.
But the Ukranian came back stronger in the third keeping par with Wawrinka and breaking him back to set up a tie-breaker. Marchenko won the tie-break 7-5, but could not keep up the momentum in the fourth as Stan wrapped up the set 6-3.
Second seed Andy Murray also moved into the quarters without breaking a sweat as he defeated Grigor Dimitrov of Bulgaria 6-1, 6-2, 6-2.
Olympic bronze medalist Kei Nishikori also moved into the quarters with a 6-3, 6-4, 7-6(4) win over big-serving Iva Karlovic and will face Andy Murray in his next match.
"Wow, it's really exciting," Williams said about the record.
"This is where it all started so it's always so magical out here for me -- 308 sounds pretty good."
Williams will face Simona Halep for a semi-final berth after the fifth-seeded Romanian dispatched Spain's Carla Suarez Navarro 6-2, 7-5.
However, the much-anticipated Williams clash in the semifinal did not pan out as planned after Venus lost to hard-hitting Czech Karolina Pliskova 4-6, 6-4, 7-6 (7/3). Both players saved a match point each to set up a tie-breaker in the third set for the match, but Pliskova downed the American 7-3.
