Serena Williams defeated the two-time defending champion, her sister Venus Williams, in the final, 7–6(7–4), 6–3 to win the ladies' singles tennis title at the 2002 Wimbledon Championships. It was her first Wimbledon singles title, third major singles title overall, and the second component of her first "Serena Slam," a non-calendar year Grand Slam and career Grand Slam. She also claimed the world No. 1 singles ranking for the first time by winning the tournament. She achieved the 'Channel Slam' (winning the French Open and Wimbledon in the same year), the first time this feat was achieved since Steffi Graf in 1996 and a feat she would accomplish again in 2015. Williams did not lose a set during the tournament.
