On Tuesday, the Williams sisters—No. 23 Venus and No. 1 Serena—will face off in the quarterfinals of the U.S. Open.
Serena is attempting to complete the calendar Grand Slam (winning the Australian Open, French Open, Wimbledon and U.S. Open in the same calendar year) for the first time in her career. She would be the first to accomplish the feat since Steffi Graf in 1988.
Serena is 15–11 against her older sister, including a 6–1 mark over their last seven matches. Their most recent match came in the fourth round of Wimbledon earlier this summer, which Serena won 6-4, 6-3. The rivalry is split at 2–2 at the U.S. Open, with Serena winning their last meeting in 2008.
In addition to the calendar Grand Slam, Serena is also searching for her seventh U.S. Open title and her fifth straight Grand Slam title.
