Tennis-Kvitova cruises in rainy Montreal, Azarenka withdraws

MONTREAL, Aug 10 (Reuters) - Former Wimbledon champion Petra

Kvitova returned to her best on Friday during a Montreal Cup

that has been dogged by rain and the withdrawal of world number

one Victoria Azarenka.

Kvitova, who also won the WTA Championships last October, is

without a title this year but her 6-1 6-1 thrashing of

ninth-seed Marion Bartoli showed she will be difficult to beat.

Bartoli said Kvitova was almost impossible to defeat when

she played at her peak and rated her a harder opponent than

either 14-times grand slam winner Serena Williams or world

number two Maria Sharapova when in form.

"“She takes away from you the control of the match," Bartoli

told reporters. "“I never felt like this against Serena or

Sharapova. When I was serving well, she returned a missile."

Aiding the cause of Kvitova, who will play Tamira Paszek in

the quarter-finals of the $2 million tournament, was Friday's

withdrawal of Azarenka with a knee injury.

Azarenka, who would lose her top ranking should Poland's

Agnieszka Radwanska win here, also withdrew from the next week's

Cincinnati Open next week but hopes to be fit for the Aug.

27-Sept. 9 U.S. Open, the year's final major.

"“I hope it's a short-term thing. I have to just stop and

take a little bit of time off because I had absolutely no rest

for a long period of time," she said.

“"If I cannot play here, there is no chance for me to play

anywhere else. My first goal is to get healthy and make sure I'm

100 percent ready to play the U.S. Open."

The Belarusian's withdrawal came two days after Sharapova

pulled out due to a stomach virus that will also prevent her

from playing in Cincinnati.

Also assisting the Montreal hopes of Kvitova and Radwanska,

whose Friday match against Chanelle Scheepers is in doubt due to

rain that has again postponed play, is the exit of last year's

finalist, Australian Sam Stosur.

U.S. Open champion Stosur lost her third-round clash with

16th seed Lucie Safarova 7-6 7-6 after wasting several chances.

Earlier on Friday, sixth seed Angelique Kerber and seventh

seed Caroline Wozniacki were successful in matches interrupted

by rain on Thursday.

Aleksandra Wozniak, on the verge of becoming the first

Canadian women to reach the quarter-finals of this event since

1992, led Christina McHale 7-6 5-2 when rain halted play.
