Indian Wells Round Four: Caroline Wozniacki vs. Urszula Radwanska

Keep the train rolling. Caroline Wozniacki has advanced to the fourth round again, dumping No. 18 Kaia Kanepi off the Indian Wells ship.

Caroline will now face an unexpected foe. Figuring all along that she would have to go through sixth-seed Svetlana Kuznetsova in the fourth round, that was not to be so. Kuznetsova went down like a sack of bricks in the second round.

She will now face upstart Pole Urszula Radwanska, who disposed of fellow wild card Alexa Glatch in straight sets.

Radwanska continues to defy odds. After taking out Kuznetsova, she took out the local Californian-born Glatch, who had nearly 100 percent of the crowd support.

Radwanska has been serving well all tournament, if she can put her mistakes behind her. She has had problems with letdowns. First, in the match against Kuznetsova, she rushed out to a massive early lead, but a single double fault turned the set against her.

Second, she came out very flat in the second set against Glatch, giving Glatch several opportunities to win the set before charging back.

Urszula is the younger sister of world No. 10 Agnieszka Radwanska.

A few stats...

• Caroline is 0-0 lifetime against Radwanska.
• Caroline is 14-5 in 2009. Radwanska is 12-5.
• Caroline is now 6-2 lifetime at Indian Wells.
• Radwanska did not qualify for the Australian Open, and her marquee victory in 2009 came against her sister in Dubai.

Urszula, like Caroline, also won the Junior Wimbledon Championship. Caroline must continue to serve at a high level and dictate points off the first serve with effective ground strokes. She also must not give up many break-point chances.

Fearless Projection: Wozniacki 6-3, 7-5.
