Wozniacki captures top ranking

Caroline Wozniacki is officially No. 1.

The tennis star from Denmark took over the top ranking from

Serena Williams on Thursday with a 6-3, 6-2 victory over Petra

Kvitova of the Czech Republic at the China Open in Beijing.

The rise to No. 1 comes in a season when Wozniacki reached the

quarterfinals at Roland Garros and the U.S. Open semifinals.

Wozniacki has 11 career singles titles and is the top seed in

Beijing, where Williams pulled out because of injury.
