That may be a possibility this week. When did it last happen, if ever?

Serena, 17 years old and ranked 24th in the world, took her first WTA Tour singles title today, winning the Gaz de France tournament here over Amelie Mauresmo of France, 6-2, 3-6, 7-6 (7-4). About five hours later, Venus, 18 years old and ranked No. 5, repeated as the winner of the IGA Superthrift Classic in Oklahoma City, beating Amanda Coetzer by 6-4, 6-0.
It was the first time that sisters had won tournaments in the same week on the WTA Tour. Two sisters played in finals on the same day in April 1991, but Manuela Maleeva lost in Spain and Magdalena Maleeva lost in Croatia.
