Los Angeles - A second pregnancy could mark the end of the tennis career of Lindsay Davenport after the 32-year-old withdrew from the Australian Open over her good news.

The announcement could have been a surprise for the mother-to-be after the three-time Grand Slam champion decided only a week ago to prepare for an entry next month into the Australian Open.

Davenport gave birth to son Jagger in 2007, saying at the time that she had retired. But she then reversed her decision, returning to tennis three months later and lifting two WTA titles in the autumn and another pair at the start of 2008.

Melbourne - Lindsay Davenport will keep her tennis career alive at age 32 after entering the 2009 Australian Open, organisers announced on Thursday,

The Californian had been on the fence about her future in recent months, last playing at the US Open and losing early.

But after pondering her situation with her husband over recent months, the 2000 champion at Melbourne Park will be entering her 11th edition at Melbourns Park from January 11.

"We are really excited that she has entered," said tournament director Craig Tiley, "She's a world-class player and a great ambassador for our sport."

Los Angeles - Three-time Grand Slam champion Lindsay Davenport has been dropping hints that her tennis career could finally be over, with motherhood fast becoming a full-time occupation.

The 32-year-old has vowed to decide in the next few days whether she will prepare for the Australian Open, which begins January 19 in Melbourne.
