Day 7 updates from the Flushing Meadows are here. Serena Williams is only three wins away from a calendar Grand Slam win, a feat last achieved by Steffi Graf in 1988. 33-year-old Serena defeated fellow American Madison Keys 6-3, 6-3 on Sunday to advance to the quarterfinals of the tournament.
“I served much better today,” Williams said. “I’m so proud I was able to serve better.
“Obviously I had to – I knew I wouldn’t have too many chances to break.”
19-year-old Keys’ challenge brought out the best from the 6-time champion.
And Serena now meets her 35-year-old sister Venus Williams, who beat Estonia’s Annett Kontaveit 6-2 6-1.
In another incident earlier, Eugenie Bouchard withdrew from the U.S. Open following a locker room accident. The 25th seed Bouchard slipped after entering the room and suffered from concussions, tournament director David Brewer confirmed.
Marin Cilic in quarterfinals
Defending champion Marin Cilic entered the quarterfinals after beating France’s Jeremy Chardy on Sunday. Cilic survived the challenge of a twisted ankle to win 6-3 2-6 7-6 (7-2) 6-0 win.
“Jeremy played really well from second set on and I was having trouble with my movement after twisting my ankle,” said Cilic, who twisted his ankle after winning the first set.
The ninth seed Croat will next play nineteenth seed Jo Wilfried Tsonga, who defeated fellow Frenchman Benoit Paire 6-4 6-3 6-4.
Earlier, third-seed Andy Murray defeated Brazilian Thomaz Bellucci in straight sets to advance to the round of 16 on Saturday. Murray won 6-3 6-2 7-5 in the New York night game.
“It was very important today,” Murray said about his three-set win.
“My last match was extremely tough physically and mentally. It was a lot cooler today, which helps, and to get the win in three sets. I get a day to recover now and get ready for the next one.”
The Briton will now face 14th seed Kevin Anderson of South Africa in the pre-quarterfinals.
