LONDON (AP) - Wild-card entry Alison Riske is one of four women keeping American hopes alive at Wimbledon.
The 126th-ranked Riske reached the third round at a Grand Slam tournament for the first time Friday, beating 44th-ranked Urszula Radwanska of Poland 4-6, 6-3, 6-4.
All four American women left in the draw - top-seeded Serena Williams, 17th-seeded Sloane Stephens, Madison Keys and Riske - will be in action Saturday.
While Williams is already a certified tennis star with 16 Grand Slam titles to her credit, Stephens, Riske and Keys are in the early stages of their careers.
``I think it's wonderful,'' said Riske, of the up-and-coming American women advancing together. ``I feel like now we have so many players. It's wonderful to see your friends doing well. We have a support system with each other.''
Riske's match against Radwanska was delayed by rain Thursday, which means she'll now play two days in a row.
She'll take on four-time Grand Slam quarterfinalist Kaia Kanepi, who eliminated No. 7 Angelique Kerber 3-6, 7-6 (6), 6-3.
Williams, the reigning Wimbledon champion, will play 42-year-old Kimiko Date-Krumm of Japan.
Stephens will complete her third-round match against Petra Cetkovska of the Czech Republic. The match was halted by darkness Friday after the two split sets.
The 52nd-ranked Keys takes on fourth-seeded Agnieszka Radwanska, a finalist last year, for a shot to reach a Grand Slam fourth round for the first time.
The American men have not been as fortunate as the women at Wimbledon this year.
For the first time since 1912, a year when no U.S. men entered Wimbledon, there are no American men still in action in the third round.
The 126th-ranked Riske, who turns 23 Wednesday, was 0-5 at major tournaments until advancing at the All England Club when her first-round opponent retired in the third set.
Riske was offered a wild card into the Wimbledon main draw after she reached the Birmingham semifinals as a qualifier two weeks ago.
``If I can play like that here, I feel like I should be able to play like that anywhere,'' Riske said. ``I just feel like the grass suits my game. I love moving forward, being aggressive. I hope to translate the results from grass on to other surfaces.''
On Friday, Riske broke in the final game, converting her third match point when Radwanska put a backhand into the net.
``I was really nervous, but I tried to keep telling myself that I wasn't really at Wimbledon,'' said Riske, of her strategy in the last game. ``I told myself if I was going to lose that last game (with) her serving I was going to do it aggressively.''
Riske won the point on 33 of 48 trips to the net, accumulating a 43-16 edge in winners.
Every match Riske wins is a confidence builder, which she says helps her pursue the right match strategy.
``I just try to play my game, be aggressive, and stay in it until the end,'' she said.
