World No.8 Agnieszka Radwanska knows what it’s like to be a teenage queen.

The Pole won her first WTA title at the age of 18 in 2007, and reached both her first Grand Slam quarterfinal and the world’s top 10 the next season. A decade later, WTA teenagers were in the spotlight on Sunday as Daria Kasatkina defeated Jelena Ostapenko to win the first all-teenaged final at a WTA event since 2009 at the Volvo Car Open.

For Radwanska, who turned professional at the age of 16, game recognizes game.

“Now I know what my opponents must have felt like back then. I have to say, the younger players on tour right now are dangerous,” Radwanska wrote in a Straits Times column this week. “We talk about it among ourselves. ‘The kids are coming!’ I think the new generation of players are just better than earlier in my career. They really play smart. From a young age, they’re already pushing to play tournaments and matches. They’re sacrificing a lot but that means they’re very good when they’re 16 or 17.”

Recognizing that she is now closer to the end of her career than the beginning, the 28-year-old reflected on playing a full schedule over the course of her years on the circuit, and how growing up in tennis has evolved.  

“When I was a junior, I played tournaments and went to school at the same time, and I went step by step. I had a pretty normal life, only unlike my friends I didn’t have much time for myself….I’ve been on tour for so long. I haven’t had any breaks. I’ve had a couple of surgeries but I always had those during the off-season and I’m always ready for the majors. I’ve played 43 Grand Slams in a row.”

She added: “My goal now is to maximize the time I have left on tour, and that means being as efficient as possible in my schedule by making the most of my opportunities.”

In the lead-up to the Oct 22-29 BNP Paribas WTA Finals Singapore presented by SC Global, the eight singles players from last year will pen a monthly exclusive column for The Straits Times. The second installment features 2015 champion Agnieszka Radwanska — read it in full here.
