Flushing Meadows, US Open, Heather Watson, Agnieska Radwanska, Ana Ivanovic, Kei Nishikori

Script: SOUNDBITE (English) Agnieska Radwanska, beat Katerina Siniakova 6-2, 6-3:

"Well the first match is always tricky, especially with different conditions every week. I'm JUST very happy to have a two sets match, and I'm just ready for the next one."

SOUNDBITE (English) Ana Ivanovic, lost Dominika Cibulkova 6-3, 3-6, 6-3:

"Yeah, definitely. I really felt like I had been improving. Last week I saw a huge improvement in my game, you know, overall; my serve was really good today, I felt. You know, that's why it's so disappointing, because it was very tough first match I think for both of us. First match of the tournament, as well. So it's not easy, but today I felt like she used her opportunities better than I did."

SOUNDBITE (English) Dominika Cibulkova, beat Ana Ivanovic 6-3, 3-6, 6-3:

"Yeah, it's still pretty far. Just passed the first round. Obviously I beat a great player, but now I want to keep going, you know. I have been far in a Grand Slam, so I know what it takes. I know what you have to do. You know, I'm just happy with my performance. I think I'm going to see a little bit from the match, but from tomorrow on I have to prepare for my second round. I just take big confidence from here. You know, I didn't play for four, five months this year, so it's, for me, huge win here in the first round of a Grand Slam."

SOUNDBITE (English) Heather Watson, lost to Lauren Davis 7-6, 7-6:

"Yeah, I was thinking a lot about this match, thinking that it was a big opportunity, and thinking about the previous years and my results here. So I think that maybe I thought about that maybe a bit too much."

SOUNDBITE (English) Kei Nishikori, lost to Benoit Paire 4-6, 6-3, 6-4, 6-7, 4-6:

"Yeah, it's very sad to lose always first round, but I think he was playing good tennis. So, I mean, I don't think I played bad. Didn't play great, but still, it's never easy first match. He's a good player. You know, try to think about next one, and I hope I can come back strong next year."
