On this date, 11 July 2015, Serena Williams at 33 years beat Spain’s Garbiñe Muguruza 6-4, 6-4 to win the Wimbledon Women’s Tennis to become the oldest winner in Open era.

Serena withstood early and late surges from Garbine Muguruza to capture the women’s title in straight sets as the 6-4, 6-4 triumph gives her 21 career Grand Slam singles titles, three behind Margaret Court for the most in history.

Williams however therefore held all four major titles at once—the Serena Slam—and earned a chance to go for the calendar Grand Slam at the U.S. Open. It’s one of the few accomplishments she’s yet to pull off in her illustrious career.

After her defeat of the Spanish youngster, Serena turned to the teary lady on the Centre Court and said: “Don’t be sad. You’ll be holding this trophy very, very soon; believe me.” And it came to pass.

Two years later, there was Muguruza with her arms wrapped around the Venus Rosewater Dish, the trophy reserved for the women’s champion, and with her dimples on display as she beamed with good reason after her 7-5, 6-0 victory over Serena’s sister, Venus Williams.
