Seventh seed Roberta Vinci, Petra Kvitova and Belinda Bencic all won their women's singles second round matches at the US Open in Flushing Meadows, New York on Wednesday.
Italian Vinci, last year’s US Open finalist, was far too strong for American Christina McHale beating her 6-1, 6-3 in a match lasting just 65 minutes.
Two service breaks in the fourth and sixth games gave Vinci the opening set 6-1 in 23 minutes.
Though the second set was a closer affair McHale dropped her serve in the seventh game and again in the ninth game to lose the set and match 6-3.
“The first round is always the toughest one,” Vinci told reporters afterwards. “But, yeah, step by step you can play more confident.
“Now I just keep going. I’m so happy that I won two matches here, tomorrow rest, and then focus for the next round.”
The 33-year-old Vinci will next face the winner of the Yulia Putintseva versus Carina Witthöft match in the third round.
In some other second round matches, Czech 14th seed Petra Kvitova defeated Cagla Buyukakcay of Turkey 7-6(2), 6-3.
Six service breaks in the opening set led to a tie-break which Kvitova won 7-2 to clinch the set 7-6.
A dropped serve by Buyukakcay in the ninth game was all Kvitova needed to claim the set and match 6-3.
