Reaction from Victoria Azarenka and Varvara Lepchenko after the Belarussian beat the American 6-3 6-4 in the fourth round of the US Open on Monday (7 September).

Script: SOUNDBITE: (English) Victoria Azarenka, beat Varvara Lepchenko 6-3 6-4:

"Just being solid, being aggressive, dictating the play. Her ball is a little bit unpredictable. You know, sometimes it comes fast and heavy; sometimes it comes high and slow. So it's a little bit more difficult to time. But just really being solid and stepping up and trying to control."

SOUNDBITE: (English) Victoria Azarenka, beat Varvara Lepchenko 6-3 6-4:

"Honestly, I don't really care as long as I win. As long as I have another opportunity to go out there and play, I will take it in any way. But definitely to have such a match of high quality that it was in the third round and then being able to overcome all those challenges, it's remarkable. Definitely very satisfying. But today it's a fourth round. The other day was third round. To measure them, I don't know."

SOUNDBITE: (English) Victoria Azarenka, beat Varvara Lepchenko 6-3 6-4:

"It was unlucky. You know, to me it was really unlucky. It is unfortunate for her. You don't want to see anybody going through an injury like this. Any injury, but this specific case. It's unfortunate, especially, you know, she's been coming back and playing quite solid. But there is no much you can do. You know, you fell. I don't know, she hit her head. That's not much you can do. It's just unfortunate."
