SOUNDBITE (English): Angelique Kerber (def. Polona Hercog 6-0, 1-0 ret.)

"Yeah, I have a lot of confidence, especially also from the last few weeks and from the whole year, actually. I mean, I'm playing one of my best tennis now. To come in here is always special. You know, for me, especially. I'm not looking too much about the seeds because I know every round it's tough in the Grand Slam. But I think that I know that I'm playing good right now. That gives me a lot of confidence. And also, the experience I had from the last years and the last weeks especially, yeah, gives me the confidence of going out and playing really good tennis."

"To be honest, it's never the way I would like to finish the match, but I went out there to feel my rhythm and start the tournament well. I played the first set really good, so this is what I will take from this match, that I'm playing my tennis. For me, it's always tricky the first few rounds. So it's always good, yeah, to have the first round done. Just now focusing on the next rounds.
