Intro:

Player reaction from Novak Djokovic, Andy Murray and Serena Williams after their respective US Open third round victories.

Script:

SOUNDBITE (English) Novak Djokovic:

"Going back to the clay court season, had an injury that I didn't know with the wrist how far it's going to stay there, if it's going to be an obstacle for me to play Roland Garros, and that has taken a lot of energy from me emotionally. Then Roland Garros, losing another final against Nadal and then bouncing back and winning Wimbledon the way I wanted and becoming No. 1 and then few days later a wedding. So these things together are very overwhelming in every way. Of course, it gave me a lot of positive energy, but of course it was very demanding."

SOUNDBITE (English) Andy Murray (on his next opponent Jo-Wilfried Tsonga):

"Well, I've had a lot of close matches with him. But I've won a lot against him, as well. So, yeah, I mean, I would say it matches up well. But he's obviously playing extremely well just now. And, yeah, I'm aware it's going to be a very tricky match."

SOUNDBITE (English) Serena Williams (says it was difficult finding her rhythm):

"Yeah, I definitely had to fight to find my rhythm. At the same time she was playing really well. She was going for shots, getting so many balls back. It wasn't like my shots, she just got them back and hit a better shot at times. For me, it was just about hanging in there."

SOUNDBITE (English) Serena Williams (on making it to the second week):

"I mean, I can't believe I'm in the second week. It's like a dream come true for me at this point. (Q: Why can't you believe it?) I'm being sarcastic."
