NEW YORK - World number 39th Peng Shuai beat compatriot Zheng Jie 6-3, 6-3 in the 2014 US Open first round match here on Monday.

It was the sixth meeting between the two on WTA tournaments, and Peng leveled the overall score to 3-3 after Monday's victory.

"You always feel nervous when you meet a person from the same country," said Peng after the match.

"We were teammates for so many years and we know each other very well."

The 31-year-old Zheng planned to represent China to take part in Incheon Asiad next month.

Peng would face the fourth seed Agnieszka Randwanska in the next round.
