NEW YORK: Three-time Grand Slam winner Lindsay Davenport took a winning first step at the US Open on Monday, opening with a 6-4, 6-2 victory over Canadian Aleksandra Wozniak.

But it may be her infant son Jagger who has the final say in how long 32-year-old mum continues her tennis career.

Californian Davenport played into the doubles quarter-finals at the Beijing Olympics after withdrawing from singles when her injured right knee flared up.

Her experience in China was also the first time at an event without her son since his birth in June 2007, and Davenport admits she felt the tug of motherhood.

“When I went to Beijing I left him for two weeks and it was heart breaking — not so much my husband, but my son,” she said. “It’s obviously not easy to be a family when you have two working parents and one travelling.

“We’ll have to see how I feel, if there’s any motivation, how it affects everybody that’s involved with us, and take it from there.”

With her previous long-term goal a Beijing appearance, Davenport has said that she will re-assess after her run in New York ends.
