Second seed Jankovic, who will replace Serena Williams as world number one on Monday, took advantage of regular errors from the unseeded Russian Petrova to clinch victory in 83 minutes.

Petrova, champion at the indoor hardcourt event in 2006, played aggressively but was never able to match the consistency of Jankovic, who took the first set thanks to a single break in the Russian's opening service game.

Petrova lost her serve early in the second, too.

She broke back for 3-3 but a desperate backhand wide gave Jankovic the advantage straight back and she stormed through to win a second successive title after last week's victory in Beijing.

"That's two titles in two weeks and I'm back up to number one so obviously things are going pretty well for me now," Jankovic, who gets to choice between prize money of US$98 500 or a Porsche car, said in a courtside interview.

Petrova's afternoon was summed up by the final game.

Serving to stay in the match, she planted an easy volley about a metre long to go 0-15 down.

She was then wrong-footed by a Jankovic backhand that flew past her for 0-30.

Petrova wafted a crosscourt forehand well long to give Jankovic three match points and handed over the first of them with an awful approach that hit the top of the net.

Jankovic had not had to do anything spectacular; just keep getting the ball back and wait for the inevitable error.

"I went for every single point and tried everything," Petrova said courtside.

"I just made too many unforced errors and the key to playing Jelena is to be consistent."
