Serena Williams

Serena Williams and her sister Venus became stars of women's tennis in the late 1990s. The sisters were African-Americans, then a rarity in pro tennis, and quickly became known for their powerful games, powerful confidence, and flashy fashion sense. Like Tiger Woods, Serena and Venus were child prodigies who began playing their chosen game before kindergarten. Serena is a year younger than Venus and (at 5'10") about three inches shorter, but she became the first sister to win a major tournament by claiming the singles title at the 1999 U.S. Open. Serena went on to become the dominant women's tennis player of the early 2000s; in 2002-03 she won the "Serena slam" by holding all four grand slam titles at once: the 2002 French Open, Wimbledon and U.S. Open titles, and the 2003 Australian Open. Her other major titles are Wimbledon in 2003 and 2009, the Australian Open in 2005, 2007, and 2009, and the U.S. Open in 2008.
