NEW YORK, NY, USA – The skies were blue, humidity nearly non-existent, and there was even a rainbow on Sunday afternoon as newly-crowned US Open champion and soon-to-be World No.1 Angelique Kerber returned to the USTA Billie Jean King National Tennis Center for the traditional Champion’s Photo Shoot.

Kerber was exhausted but beaming, walking the grounds with the air of a woman who believes in her bones that she is not only playing the best tennis of her career, but that there’s an even better version of herself and her game past the horizon.

WTA Insider caught up with Kerber to discuss what lies ahead.

WTA Insider: It’s been less than 24 hours since you got your hands on the US Open trophy. You must be tired.
Kerber: I am a little bit tired but also exhausted, excited, everything. After last night, it’s just the best feeling right now. To go home with my Grand Slam title again, my second one in one year, and of course with No.1, it means a lot to me. I’ll just try right now to enjoy every moment and everything that I did in the last few weeks.

WTA Insider: Three Grand Slam finals, two Slam titles, and World No.1. Which one of those accomplishments amazes you the most?
Kerber: Actually I think the Grand Slam titles first, because that’s always something I was always working so hard for, to win the major titles. To win two right now and to be in one final at Wimbledon, that means to me everything.

To then be No.1, what I was always dreaming when I was a kid, that shows me I played a really consistent year. To be No.1 you have to play great, not one day or one week, you have to play very well a few months, and this is also incredible to me, actually.

WTA Insider: I remember speaking with you on a couch when you qualified for your first WTA Finals back in Istanbul. At the time you didn’t seem convinced that you were one of the eight best players in the world. Take me back to that time, that breakthrough, and what it felt like then when you were trying to be comfortable with being a good player.
Kerber: When I reached my first Top 10 and also my first WTA Finals, being with the best players of the world at the end of the year, of course I was a little bit not sure what happened. I didn’t have the experience. It was everything new for me. I had to get used to everything.

Right now, years after, I learned a lot. I think I was growing as well. I was growing every year. I improved my tennis, I improved my personality and everything. This gives me so much confidence as well because I can look back and I can say I was learning. I was learning every year and this is what makes me proud. I took the chance to be now where I am. Finally I am still the same person because I am still Angie like I am a few years ago. This is what also for me really important, to stay how I am.

WTA Insider: When I see you now, you seem very calm and comfortable in your own skin.
Kerber: I’m feeling much for confident now in my skin and how I am. I think it’s because of my experience I know what’s happened, I know how to deal with pressure, how to deal with the things I have to do off court. That’s what gives me the confidence to, you know, dressing up, speaking, working, being how I am. Of course it takes a little while to get where I am, and it was really tough but really good.

WTA Insider: You mentioned the word pressure. What’s the most high-pressure match you feel you’ve played?
Kerber: To be honest, this match this year in Australia, the first round, that was a match where I was feeling a lot of pressure because last year I lost in the first round. I put so much pressure on myself. I didn’t want to lose in the first round.

This is maybe from this year one of the matches where I remember my pressure was really high. After the win when I was also match point down, I was feeling like ok, the pressure was gone. I won the first round and now I can go for it. So for this year I can say this was the match.

WTA Insider: When we talk about your career, there are three matches that always come up. That Australian Open match is one. The match against Victoria Azarenka here, that you lost. The match against Lucie Safarova in Singapore, that you lost. Talk about how important it is to learn from your losses.
Kerber: This is really important to learn from your losses but also as well, learning from your wins. After every match you have to sit down and think what I did good and what I did wrong. I learned a lot from really tough and close matches that I had in the past, especially the last years when I played so many great matches against great opponents.

This year, I had confidence because I knew that I could play good matches because they’re always tough but I have to go the last step and just go for it. That gives me a lot of confidence and maybe a little bit less pressure.

WTA Insider: You’re the World No.1 now. We’ve seen in the past that players who get to No.1 get comfortable with their game and don’t want to make changes. It’s too risky. How does your game get better from here and can you motivate to take those risks?
Kerber: No, I think my motivation is really high, especially right now after this title in New York. I will still try and improve my game because I know that I can still improve my serve and improving a few things on my game. It’s what I will try and do over the next few weeks and in my pre-season for next year. There are still a few things that I know I can do better. That gives me a little bit of confidence to know that I can still play better, maybe a little bit more aggressive, moving better, because there is still a little bit percent where I can go for it.

WTA Insider: So we haven’t seen Peak Angelique Kerber yet?
Kerber: We will see. Of course I’m playing the best tennis in my career, but I’m trying to be better and better. I’m trying to motivate myself to be better in my matches and in practice. I will try to still play my best tennis in the next months.

Kerber will next play at the Dongfeng Motor Wuhan Open and China Open during the upcoming Asian Swing. Hear more from Kerber and coach Torben Beltz in the latest WTA Insider Podcast:
