See main article: 2003 Wimbledon Championships. Defending champion Serena Williams defeated her sister Venus Williams in a rematch of the previous year's final, 4–6, 6–4, 6–2 to win the ladies' singles tennis title at the 2003 Wimbledon Championships.[1] It was her second Wimbledon singles title and her sixth major singles title overall.
This was the first Wimbledon appearance of future world No. 1 and five-time major champion Maria Sharapova, who lost to Svetlana Kuznetsova in the fourth round. Sharapova would win the title the following year. It was also the first Wimbledon appearance of future champion Marion Bartoli, who lost to Daniela Hantuchová in the first round. The semifinals featured the top four seeds, which last occurred in 1995.[2]
This was the first major since the 1987 Australian Open to not feature either Monica Seles, Steffi Graf, or Arantxa Sánchez Vicario.
