Intro:

Reaction from Djokovic, Sock and Keys after their victories at the French Open.

Script:

SOUNDBITE: (English) Novak Djokovic, defeated Jarkko Nieminen 6-2, 7-5, 6-2 (Q. It could have been a tricky first round. I guess you're pretty happy with the test you had today?)

"It was a test, it was a challenge for me to come back to the court again after first match after Rome finals. And obviously it's been a year since I played on Philippe Chatrier, and nice memories. Of course, I was aware of the quality and experience of my opponent today, who has shown, and especially in the second set, why he's been around the tour and a successful, consistent player for so many years."

SOUNDBITE: (English) Madison Keys, defeated Varvava Lepchenko 7-6, 6-3 (Q. I think you said this was your goal, to win first round. How does that feel, especially on the red stuff?)

"You know, just really happy to get through the first round. I've only done it one other time before. Just really happy with how I played today and fought. Hopefully can just kind of get a momentum going."

SOUNDBITE: (English) Jack Sock, defeated Grigor Dimitrov 7-6, 6-2, 6-3 (Q. Did you play any better than that?)

"Can I play better than that? Yeah, I think there is always room for improvement. Yeah, today was a great match for me. Things that I look to do well when I'm playing my matches I thought I did very well today: serving, forehand. Obviously most people know the things I look for the most. I thought I executed them very well. For the most part I took care of my serve fairly well and was able to get into a lot his service games and make him play some balls. I was fortunate enough to get through."
