sister serena

Venus Williams plans to make her comeback in an exhibition match against her sister Serena in Colombia next Wednesday after being forced to pull out of the U.S.

Open because of an immune system disease.

WIMBLEDON, England, July 4 -- It's rare to see Venus Williams telegraph defeat on Wimbledon's Centre Court, where she has triumphed so many times.

But masterful serving and ruthless groundstrokes from her younger sister, Serena, who competed without regard to family ties, had Venus doing just that in Saturday's all-Williams Wimbledon singles final.

This year, it was Serena who raised the prized Venus Rosewater Dish after reducing Venus, a five-time Wimbledon champion, to a tentative, error-prone also-ran.

Five-time champion Venus Williams recovered from an early stumble in her opening match at Wimbledon on Tuesday to beat Stefanie Voegele of Switzerland 6-3, 6-2.

It was Williams' first appearance on Centre Court since the 2008 final, when she beat sister Serena for her second Wimbledon title in a row.
