After beating some of the top seeds in the sport, including her sister Venus and Maria Sharapova, Williams accomplished what’s been dubbed the “Serena Slam” for the second time – winning four Grand Slam tournaments in a row, beginning with last year’s U.S. Open, then the Australian Open, the French Open and on Saturday, Wimbledon. Williams won 6-4, 6-4 on Centre Court at the Wimbledon women’s finals against opponent Garbine Muguruza of Spain. Although she didn’t want to discuss the prospect of a second “Serena Slam” prior to the finals, she’s now accomplished it, and if she wins the U.S Open in New York City this August, she will be the first woman to win the Grand Slam title – all four Majors in a calendar year – since Steffi Graf in 1988. She’d also tie Graf’s record of 22 Major championships for her career. This means both women would be in second place to Margaret Court’s all-time record of 24 titles. Muguruza was confident going into the match, having beat Williams 6-2, 6-2 at the French Open last year in a surprising upset. “She knows that I can win against her, that I’m not afraid,” Muguruza told reporters at a pre-match press conference. “I don’t think she’s really used to this. Serena, she doesn’t lose so many matches in the year.” This is Williams’s 18th Wimbledon tournament, and her sixth singles win there.
