DOHA, Qatar -- Caroline Wozniacki will finish 2010 as the No. 1 player in the world after posting another round-robin victory Thursday at the season-ending WTA Championships.

The 20-year-old top-ranked Wozniacki needed to win a pair of round-robin matches this week in order to keep Russian Vera Zvonareva from having a shot at overtaking her atop the rankings. The Dane went 2-1 in the four-woman Maroon Group.

The former U.S. Open runner-up Wozniacki came from behind to beat fourth- seeded French Open champion Francesca Schiavone 3-6, 6-1, 6-1 on the hardcourts at Khalifa Tennis Complex.

"2010 has been the most amazing year in my career during which I realized my dream of becoming world No. 1," Wozniacki said. "Capturing the year-end world No. 1 ranking is a huge accomplishment for me and I am thrilled that all the hard work has paid off."

Wozniacki is the first player from Denmark and becomes only the 10th player to end the season as No. 1 since the WTA rankings were introduced in 1975.

Meanwhile, the U.S. Open and Wimbledon runner-up Zvonareva, who is 2-0 in the White Group this week and was idle here on Thursday, needed Wozniacki to lose a pair of round-robin matches while she reached the final here.

Zvonareva has qualified for Saturday's semifinals.

Third-seeded two-time reigning U.S. Open champion Kim Clijsters (2-0) booked a spot in the semis by holding off eighth-seeded Victoria Azarenka 6-4, 5-7, 6-1. The Belarusian Azarenka, fresh off her title in Moscow, dropped to 0-2 in the White Group this week.

Clijsters, who captured the WTA Championships back-to-back in 2002 and 2003, will battle Zvonareva for first place in the White Group here on Friday.

In some other Maroon Group play on Day 3, seventh-seeded Russian Elena Dementieva overcame fifth-seeded French Open runner-up Samantha Stosur 4-6, 6-4, 7-6 (7-4). The Aussie Stosur (2-1) still qualified for the semifinals, while Dementieva improved to 1-1 for the week.

Friday's other round-robin bouts will pit Schiavone (0-2) against Dementieva and sixth-seeded former world No. 1 Jelena Jankovic (0-2) versus Azarenka.

This prestigious event features the top-eight players in the world. Round- robin tennis is the order of the day through Friday, as the top- two players from each group advance to the semis. The lucrative finale will be staged on Sunday, with the winner pocketing at least $1.55 million
