Brisbane, 9 January 2011 | AAP

Rising Czech Petra Kvitova continued her Australian love affair on Saturday night by trouncing Andrea Petkovic to claim the Brisbane International tournament.

Kvitova, a quiet achiever throughout the week, again surprised the crowd at Pat Rafter Arena to take her second career title with a 6-1 6-3 triumph over the German world No.32.

The 20-year-old’s maiden title came in Hobart two years ago and her display on the Brisbane hard-court showed the lanky left-hander would be a worthwhile smokey for the Australian Open.

The WTA newcomer of the year in 2010 and world No.34 was on fire as she blitzed Petkovic in 71 minutes with her impressive serve and sweeping forehand.

Kvitova hardly put a foot wrong from the moment she successfully challenged the first point, having a winning ball overruled.

She broke immediately, earned through a Petkovic double fault which epitomised her strangely off-key night.

The German political science student hadn’t conceded a set all tournament but lost the first swiftly as her game, possibly hampered by a back problem, never came together.

Petkovic only held serve once and when she failed to convert one of three break points at 4-1 down the writing was on the wall.

She started the second set better but lost her serve to love in the sixth game.

To her credit Petkovic broke back but then undid her good work by double-faulting in the next game for Kvitova to take a 5-3 lead and then clinically close out the match.

The 183cm-tall Czech, who upset third seed Nadia Petrova in the first round and also stunned another Russian, Anastasia Pavlyuchenkova, in the semi-finals, was given little chance all week.

Best known for her surprise run into the Wimbledon semi-finals last year, Kvitova was given just one match on centre court before the one-sided final.

Petkovic, who eliminated Australians Jelena Dokic and Jarmila Groth, won only seven of her 22 points on serve in the disastrous first set, but wouldn’t blame the result on a back injury she sustained following her semi-final win over Marion Bartoli.

“I have a little back problem but it was not a big deal,” she said.

“I think it’s all about my movement, my footwork wasn’t well and I felt heavy on the court.

“The two things come together, me feeling not so well and Petra playing unbelievable, just made such a huge difference today.

“When she’s on fire it’s tough to get into the match, you only have two or three chances.”

Kvitova’s victory is set to see her rise to a career-high No.28 in the WTA rankings.
