Reaction after the first round matches at the US Open.

SOUNDBITE (English): Roberta Vinci (def. Anna-Lena Friedsam 6-2, 6-2)

"It's tough to repeat of course the results of last year (Smiling.) But I'm No. 7, so of course I have a lot of pressure. They expect me semifinal, quarterfinal, step by step and match by match. So now I'm really happy that I won the first round. Tomorrow relax and play the second round. I don't know the opponent right now, but will be of course a difficult match, tough match. I try my best and don't think that I have a lot of points to defend."

SOUNDBITE: (English) Saisai Zheng, (beat Monica Puig 6-4, 6-2):

"Very happy about the win today. It's always tough in the first round to play anybody, especially as she just won the Olympic gold medal. It's also a lot of pressure for her today I think. The crowd were really crazy for her. I did my plan well, I think I executed my plan well today. And I changed a lot, the high, the low, the fast and the short, I think they worked very well."
