LONDON, England - The weekend rain means that Day 3 at the Olympic Tennis Event will be a bumper one. Headlining the action on Centre Court will be Caroline Wozniacki against Yanina Wickmayer, while over on Court 1 Serena Williams takes on one half of tennis' other sister act, Urszula Radwanska.

Monday, Second Round

Centre Court
Yanina Wickmayer (BEL #31) vs. [8] Caroline Wozniacki (DEN #8)
Wozniacki leads 5-0
On Day 1, Caroline Wozniacki almost fell victim to an inspired Brit running high on Olympic spirit. On that occasion, she upped her game just in time to avoid that upset and she will need to raise it a notch further when she takes on in-form Yanina Wickmayer in the second round.

Although Wozniacki has won all five of their meetings, in recent months, Wickmayer has started to return to the sort of form that took her to within a whisker of the Top 10 a few years back. Her big serve and even bigger forehand are ideally suited to the grass and if either of these start to find their range then Wozniacki could be in for a long afternoon.

Court 1
[4] Serena Williams (USA #4) vs. Urszula Radwanska (POL #44)
Williams leads 2-0
In 2012, Urszula Radwanska has watched on as her sister, Agnieszka, has established herself as one of tennis' dominant forces. However, judging by her stellar performances of late, Urszula's time out of the spotlight could soon be coming to an end. Quarterfinals in Brussels, Stanford and Carlsbad, and a runner-up finish on the grass of 's-Hertogenbosch, have catapulted her not only to a career-high ranking of No.44, but also into the Olympic team.

Now she gets the chance to see just how far she has progressed when she takes on a red hot Serena Williams. Titles at Wimbledon and Stanford have helped the American compile a 12-match win streak and, worryingly for Radwanska, her clinical dismissal of Jelena Jankovic in the first round suggests that the rustiness that occasionally accompanies her opening matches at the All-England Club is nowhere to be seen.

Carla Suárez Navarro (ESP #45) vs. Kim Clijsters (BEL #36)
Clijsters leads 1-0
In addition to the four Slams, 37 WTA titles and 20 weeks spent at No.1, after Kim Clijsters retires later this summer, she will always be remembered for her epic rivalry with fellow Belgian Justine Henin. And on Monday, she takes on Carla Suárez Navarro, a player who idolized her great rival and has a single-handed backhand every bit as elegant.

This stroke was on full display in the first round as Suárez Navarro caused the first major upset of the tournament by dumping out No.5 seed Samantha Stosur in a three-set thriller. Clijsters, on what was remarkably her Olympic debut, enjoyed a rather more routine win over Roberta Vinci and will be looking to continue this rich vein of form. The two have met only once previously, at last year's Australian Open, when Clijsters ran out a comfortable straight set winner.

Around the grounds?
After Sunday's near-washout, a number of first round matches still need to be completed, including the clash between Sydney gold medalist Venus Williams and Sara Errani. Among the other big names in action are Victoria Azarenka, Petra Kvitova, Kim Clijsters, Angelique Kerber and Ana Ivanovic.
