BEIJING — World number one Serena Williams sailed through to convincing victory in the China Open Sunday.

She won her tenth title of the year with over world number 11 Jelena Jankovic of Serbia.

The Serb only briefly threatened her opponent, breaking the American’s serve in the third game of the second set.

But any hope she had was quickly extinguished by the top seed in Beijing, who won the set’s remaining games.

The 32-year-old power hitter has already secured the year-end world number one ranking, and last month became the first woman to surpass $9 million in prize money in a single season.

Williams last claimed the China Open in 2004, while Jankovic won the tournament in 2008.
