2011 WTA Commonwealth Bank Tournament of Champions winner Ana Ivanovic from Serbia wears a Balinese traditional costume as she poses for photographers with her winner's trophy in Nusa Dua, Bali, Indonesia on 06 November 2011.

Ana Ivanovic successfully defended her Tournament of Champions title with a 6-3, 6-0 win over Anabel Medina-Garigues in Bali, Indonesia, yesterday.

The Serb gained momentum against her Spanish opponent early and was untroubled throughout in winning her first final since the same WTA event last year.

"I feel great. Very unexpected, actually," said Ivanovic. "I think I played an impeccable match today. Really I didn't do much wrong."

Ivanovic celebrated her 24th birthday with the US$210,000 prize.

Nadia Petrova of Russia took third place by defeating Daniela Hantuchova of Slovakia, 6-2, 5-7, 6-0. Hantuchova filled in for German Sabine Lisicki, who had to pull out with a back injury.

In Moscow, Anastasia Pavlyuchenkova overpowered Lucie Safarova 6-2, 6-4 in the second reverse singles to pull host Russia level with the Czech Republic at 2-2 in their Fed Cup final yesterday.

The 15th-ranked Pavlyuchenkova, who replaced Maria Kirilenko after the latter's straight-sets loss to Petra Kvitova on Saturday, was just too strong for the Czech No. 2 and set up a doubles decider for the title later yesterday.

Earlier, Wimbledon champion Kvitova beat Svetlana Kuznetsova 4-6, 6-2, 6-3 in the first match of the day to put the Czechs within a point of clinching their first Fed Cup title as an independent nation after splitting from Slovakia in 1993.

Their last triumph came when, playing as Czechoslovakia, they beat the former Soviet Union 2-1 in the 1988 final.

In-form Kvitova fought back from 0-3 down in the final set to reel off the next six games for her 12th consecutive victory since last month's China Open. The world No. 2 also went undefeated indoors for the whole year, recording her 21st victory this season.
