Injured Williams withdraws from Australian Open

Venus Williams withdrew in the second game of her third-round

match against Andrea Petkovic at the Australian Open on Friday

after appearing to aggravate a stomach injury.

The seven-time Grand Slam winner dropped serve in the opening

game and Petkovic was ahead 30-0 when Williams stretched to the

right to return service. She immediately cried out and clutched her

stomach on the right side.

Williams injured a muscle between her stomach and groin

Wednesday when she twisted for a volley in her second-round win

over Sandra Zahlavova of the Czech Republic. Williams has never

before withdrawn due to injury during a Grand Slam match.
