After beating American teenager Madison Keys, 6-3, 6-2, in the second round of Beijing, Agnieszka Radwanska says she likes the 18-year-old’s future prospects. Keys is the youngest player in the WTA Top 40.

“I played her at Wimbledon a few months ago, so I kind of knew what to expect, especially the big serve," Radwanska told reporters. "We played a really long three-set match there. She was really serving unbelievable. So I knew I had to stand two steps backwards to reach that serve. But I don't think her percentage of first serves was as good as the matches before—it was a little bit easier for me today.

"But she's one of the youngest talented players coming out. Last year I was asked me to name which of the players can be the most dangerous to the top seeds, and I actually said it's Madison Keys, because she can play very good tennis. In a couple of years we're going to see her more often."
