Olympic champion Zheng Qinwen <\/b>fought back from a set down to beat world number 50 Amanda Anisimova 4-6 6-4 6-2 on Louis Armstrong Stadium.<\/p>\n
Anisimova raced out to a 5-1 first-set lead but twice failed to serve it out, before breaking Zheng for the third time to clinch the opener.<\/p>\n
But Zheng, a little over three weeks on from her Olympic triumph in Paris, recovered well and served superbly from then on.<\/p>\n
The Chinese seventh seed said it was the “typical match” she would have lost in the past, adding that victory was “one step forward in my mental side”.<\/p>\n
“Usually after huge success I will get a little bit too high, and until the reality slap me down again and I come back to the ground,” Zheng said.<\/p>\n
“So this time when I get a success, I’m telling myself, I don’t want to let this happen. I’m really happy to get this match, because she’s really tough to face.”<\/p>\n
Australian teenager Iva Jovic<\/b> pulled off the biggest upset of the opening day in New York, with the 16-year-old beating world number 40 Magda Linette 6-4 6-3 for her first WTA match win.<\/p>\n
Meanwhile, France’s Clara Burel<\/b> claimed an impressive comeback victory against 2017 champion Sloane Stephens.<\/p>\n
Stephens won the first nine games of the match in 33 minutes but Burel somehow clawed her way back from a break down in both the second and third set before wrapping up a 0-6 7-5 7-5 win.<\/p>\n
Burel will face three-time runner up Victoria Azarenka<\/b> of Belarus, who beat Ukraine’s Yulia Starodubtseva 3-6 6-1 6-1.<\/p>\n
Daria Kasatkina,<\/b> the 12th seed, beat Romania’s Jaqueline Cristian 6-2 6-4 to progress, while Ukrainian 27th seed Elina Svitolina<\/b> came through in three sets against Maria Lourdes Carle of Argentina.<\/p>\n
Wimbledon champion Barbora Krejcikova <\/b>also progressed, beating Spanish qualifier Marina Bassols Ribera 7-6 (7-3) 6-2, while American 13th seed Emma Navarro<\/b> beat Anna Blinkova 6-1 6-1 in just 59 minutes.<\/p>\n
However, Maria Sakkari<\/b> became the first top-10 player to fall, with the ninth seed forced to retire injured after losing the first set to Wang Yafan.<\/p>\n
A visibly upset Sakkari received treatment from the trainer to her shoulder and neck midway through the first set, and was ultimately unable to continue into a second.<\/p>\n
American 14th seed Madison Keys<\/b>, runner-up at Flushing Meadows in 2017, moved past Katerina Siniakova of the Czech Republic 6-4 6-1.<\/p>\n<\/div>\n
