Defending champion Agnieszka Radwanska has kicked off her 2017 campaign in New Haven with a 6-3 7-5 win over Eugenie Bouchard on Tuesday.
Radwanska advances to a quarterfinal meeting with eighth seed Peng Shuai, who beat Mirjana Lucic-Baroni.
It was a second-round battle between players who have both struggled for form this season; Radwanska ended 2016 ranked third yet has since slipped to 10th, while Bouchard now slumps to 13-17 in 2017, having failed to win back-to-back matches since Madrid.
Radwanska largely controlled the match against the error-prone former world No.5, who sprayed 25 unforced errors in the first set alone and finished the match with seven double faults.
“I had so many chances from the beginning of the [second] set,” said Radwanska, who sealed victory on her fourth match point.
“So many 40-15 games, so many break points. When you’re not using those kind of chances against good players, there’s always trouble.
“But I’m very happy I could finish the match in two sets.”
Also advancing to the quarterfinals were Daria Gavrilova – a 7-5 7-6(6) winner over Timea Babos – and qualifier Elise Mertens, who overcame Daria Kasatkina 6-2 7-5.
Carla Suarez Navarro sealed a spot in the second round after getting past an injured Jana Cepelova.
The US Open series usually means one thing is for certain – John Isner wins a lot.
And the American proved that was the case with another victory, this time in the second round in Winston-Salem over Andrey Kuznetsov.
Isner’s 2-6 7-6(5) 6-3 win over the Russian sends the third seed into the last 16 where he will face Borna Coric.
Isner last week reached the semifinals in Cincinnati; a few weeks earlier he won the title in Atlanta.
In between – when he stepped across the border into Canada – he lost in the first round in Montreal to Juan Martin del Potro.
Coric advanced on a day the ATP’s Next Gen stars were out in force.
Seeded 14th, the Croatian recovered to beat local Donald Young 4-6 6-4 6-2, while American teen Taylor Fritz, a wildcard at Winston-Salem, brushed aside Japan’s Yuichi Sugita for the loss of just five games.
No.13 seed Hyeon Chung won an all-Next Gen battle with Andrey Rublev, beating the Russian 5-7 6-1 6-1.
Chung next faces Julien Benneteau after the Frenchman upset defending champion Pablo Carreno Busta, while Fritz has seventh seed Paolo Lorenzi next up.
Meanwhile, top seed Roberto Bautista Agut began his tournament with a 6-4 6-3 win over Dusan Lajovic, and will take on Marco Baghdatis in the last 16.
