World ranking: 4
Winner (2000 & 2001)
Most of the spotlight might have been snatched by her younger sister, but Venus Williams is still a force to be reckoned with.
Despite having to swallow the bitter pill of losing to Serena in four straight Grand Slam finals over the past year, she remains her sister's driving inspiration
But it is at SW19 that the two-time Wimbledon champion has enjoyed some of her greatest success, beating Lindsay Davenport and Justine Henin in the 2000 and 2001 finals respectively.
Her 2003 season began with the disappointment of a three-set loss to Serena at the Australian Open - though she has since picked up a title in Antwerp.
And, with a new interior design business to occupy her, doubts remain as to whether Venus is as completely focused on the game as her sister appears to be.
But, provided she can avoid the sort of early upset she is occasionally vulnerable to, Venus should be able to use the fast grass courts at Wimbledon to exploit her physical prowess to the maximum.
