Williams sisters

The Williams sisters are two professional American tennis players: Venus Williams (b. 1980), a seven-time Grand Slam title winner (singles), and Serena Williams (b. 1981), twenty-one-time Grand Slam title winner (singles), both of whom were coached from an early age by their parents Richard Williams and Oracene Price. There is a noted professional rivalry between them – between the 2001 US Open and the 2009 Wimbledon tournaments, they have met in eight Grand Slam singles finals. They remain very close, often watching each other's matches in support, even after one of them has been knocked out of a tournament.

Both sisters have been ranked by the Women's Tennis Association at the World No. 1 position. In 2002, after the French Open, Venus Williams and Serena Williams were ranked No. 1 and No. 2 respectively. During the 2010 French Open, they became the co-world no.1 players in women's doubles, in addition to holding the top two positions in singles tennis.

Both players have won four gold medals at the Summer Olympics Games, one each in singles and three in doubles - all won together - the most of any tennis players. As a duo, they have also completed the Career Golden Slam in doubles.
