 Sun enjoyed only her second victory against a top 10 player |
Patty Schnyder was the first seed to fall in the women's Pilot Pen event in New Haven as she went down 6-1 6-3 to Chinese qualifier Sun Tiantian. The sixth-seeded Swiss admitted she was surprised by the world number 93, who came through three games in qualifying.
"I was not on my game and she really mixed up her serves well. I really didn't know her," Schnyder said.
Russia's fifth seed Svetlana Kuznetsova had to work hard to beat American Jill Craybas 6-7 (6-8) 6-1 6-1.
The first set lasted an hour and 22 minutes, including a marathon seventh game that went to deuce 14 times before Craybas held serve.
But the local favourite's resistance did not last as the 2004 US Open champion raced through the second and third sets.
"The rallies were long and it was a very hard match," said Kuznetsova. "I just felt so tired. You have bad days sometimes, and I'm very happy I got through."
