At this time last year Belinda Bencic was the No. 1 ranked junior playing in the U.S. Open junior tournament, aiming to become the first girl since 1990 to win three junior Slams in one year. A year on and Bencic earned direct entry in to the main tournament and the 17-year-old Swiss prodigy is into the fourth round of a Slam for the first time after stunning sixth seed Angelique Kerber in the third round. Bencic, who was coached from childhood by Martina Hingis' mother, Melanie Molitor, has soared up the rankings in her first year on the WTA tour. She began the season ranked No. 212 and is up to a career-high No. 58, the youngest player in the top 100. Earlier this season she made her first Premier-level semifinal at the Family Circle Cup in Charleston, South Carolina. Bencic is the real deal and young name we'll be seeing often in the second week of Slams. But who knew it would be so soon?
SI.com caught up with Bencic recently to talk about her first year on the pro tour, growing up Swiss, and, before we were so rudely interrupted by Australian Open champion Stan Wawrinka, selfies with Roger Federer.
SI.com: So when was the first time you realized you could make a living playing tennis?
Bencic: I don't know, because in the beginning I wasn't that good [laughing]. I was losing the first matches I played. But I started getting into it and started winning and it made it more fun, and I started to play more tournaments. So there wasn't a day. It was gradual.
SI.com: Is there a match that stands out to you as the one that made you believe you could be a professional?
Bencic: I just remember my first match. I lost 6-0, 6-0.
SI.com: When was that?
Bencic: I was four and my opponent was 10. It was a national tournament.
SI.com: Do you remember how you reacted after losing? Were you sad? Angry?

We're grading on a curve here. Given H&M's recent debacles, we give this a pass.
Bencic: My dad always told me that when I play older opponents, which I always did, that if I won just two games in each set then I already won in my mind. So sometimes I would come to the net and say "I won!" And the girl would say "No, you didn't."
SI.com: You're still young. Do you still have that mindset?
Bencic: No. Now I try to win six games each set [laughs].
SI.com: You're now a staple in the WTA locker room. Do you remember the first time you were walking around in there and were starstruck?

Bencic: Yes. Stefanie Voegele, Monica Puig, Jana Cepelova and also the younger players. Dominika Cibulkova and I talk. You know, just the Czech and Slovak clique.

Bencic: I like Rihanna, Calvin Harris, and Katy Perry.
SI.com: Do you listen to music when you go on court?
Bencic: No, no I can't do that. I listen to music the morning before or the evening before. But when I go on the court I don't because then I always have the music in my head. It's like the tiebreak and I'm like [starts dancing].
SI.com: What do you do to keep your mind off tennis?
