Serena and Venus Williams raise their trophies after winning their Ladies’ Doubles final match of the Wimbledon Lawn Tennis Championships at the All England Lawn Tennis and Croquet Club on Saturday (July 7, 2012) in London, England.

It was a race to the top in the singles match in Charleston, S.C. at the Family Circle Cup, the Williams sisters won, twice on Friday, April 5. Venus and Serena Williams will face-off today. They haven’t met in a tournament since the 2009 Tour Championships in Qatar. The younger Serena, 31, holds a 13-10 lead, although they’re 1-1 on clay.

“For the record, we’ve never played two matches on the same day,” Serena tells the crowd after her matches at the Family Circle Tennis Center. “You guys had a real treat.”

It’s the 24th time in their careers where they go head-to-head.

Serena ranks No. 1 in the world winning Wimbledon, the Olympics and the U.S. Open since capturing last year’s Family Circle. She recently added a sixth Sony Open crown, rallying past Maria Sharapova for her 48th career WTA crown.

Venus, 32, has lost four straight to Serena since a victory in Dubai in 2009. The older Williams hasn’t won a major since Wimbledon in 2008.
