NEW YORK – China's Wang Qiang upset French Open champion Ash
Barty 6-2, 6-4 on Sunday at the US Open to reach a first career grand
slam quarter-final.
The 18th-seeded Wang prevailed on fourth match point against second
seed Barty who won both of their previous meeting but failed to
convert on all of her nine break points and piled up 39 unforced
errors, to Qiang's 14.
"I was very focused, I tried to hit aggressive," said Wang who next
meets six-time champion Serena Williams or Petra Martic but is not
getting too wound up about her upcoming task.
"That's my coach's home work. My coach will tell me how to play next.
I want to just enjoy it," she said.
Other action Sunday included former finalist Karolina Pliskova v
Johanna Konta on the women's side, while men's fourth-round action
included a duel between title holder Novak Djokovic and 2016 champion
Stan Wawrinka, plus Roger Federer v David Goffin.
