Happy birthday to Venus Williams, 21 Grand Slam title holder. Williams has won more Olympic gold medals, three, than any other female tennis player, and is only the second player to have won Olympic gold in both singles and doubles at a single Olympic Games. She and her sister, Serena, who have both been ranked World No. 1 at one time or another, have faced each other in 8 Grand Slam singles finals and hold a record for being the only two players to have ever faced each other in 4 consecutive Grand Slam singles finals.
