Venus and Serena not ready for retirement

DOHA: Venus and Serena Williams, ghetto-kids turned multi-millionaire senior citizens of women's tennis, go into the WTA Championships here insisting retirement is not an option.

In the past two years, the American sisters have seen former rivals Kim Clijsters and Justine Henin quit before deciding to return to the tour.

Venus, a year older than her sister at 29 and the holder of seven Grand Slam titles, and Serena, with 11 majors to her name, are still such an impressive combination that they have also qualified for the four-team doubles here.
