Serena vs. Venus

Williams played her older sister Venus in 31 professional matches starting in 1998. Overall, Serena is 19–12 against her sister. The pair played 15 times in Grand Slam singles and 13 times in other tournaments (including 11 finals). They have met in nine Grand Slam tournament finals, with Serena winning seven times. Beginning with the 2002 French Open, they played each other in four consecutive Grand Slam finals, which was the first time in the Open Era that the same two players had faced off in four consecutive finals in Grand Slam singles.

When both the Williams sisters entered the top ten and started facing off in tournaments, rumors of match fixing started to circulate. John McEnroe, while commenting on the 2000 Wimbledon semifinal between the two sisters, said that "Serena may not be allowed to win. Richard may have something to say about this." After losing to Venus at the Indian Wells quarterfinals in 2001, Elena Dementieva claimed that Richard Williams had decided the results of matches between the sisters. Shortly after that, Venus pulled out of her Indian Wells semifinal match against Serena at the last minute, claiming tendinitis; this led to much speculation in the press, and some spectators demanded their money back. The final, in which Serena defeated Kim Clijsters, was marred by the behavior of the crowd toward Williams and her family.
