Nadia Petrova routs Caroline Wozniacki to win Tournament of Champions

Nadia Petrova: Sofia triumph ensures she will finish the year in the top 10.

Nadia Petrova dropped just three games as she thrashed top seed Caroline Wozniacki to clinch the season-ending Tournament of Champions.

The Russian took just one hour and 27 minutes to claim a 6-2 6-1 victory that secured her third WTA title of the year and will see her climb to 12th in the rankings.

Petrova, who arrived in Bulgaria on the back of a doubles triumph in Istanbul last week, said. "What a finish to the season - a title in doubles and now in singles.

"Now I'm just looking forward to a rest and getting strong and healthy for next year."

Petrova broke Wozniacki's first serve and extended her lead with a further break in the fifth, a string of powerful cross-court drives doing the damage.

She saved a break point soon after but that proved a fleeting threat to her momentum, the set wrapped up in 50 minutes.

Wozniacki surrendered serve again at the start of the second set and could only stop the rot briefly four games later; the contest long over by then.

Her consolation is a year-end top ten ranking, her run to the final ensuring she climbs one spot from 11th, leapfrogging Marion Bartoli.
