Serena Williams defeated the defending champion Maria Sharapova in the final, 6–4, 6–4 to win the women's singles tennis title at the 2013 French Open. It was her second French Open singles title, her 16th major singles title overall, and she completed a double career Grand Slam in singles with the win. She also became the oldest woman to win the French Open (a record she later surpassed herself in 2015) and set a record for the longest gap between successive French Open titles (her last being in 2002). With the win, Williams expanded a win-streak to 31 matches, dating back to the Miami Open. She lost only one set during the tournament, to Svetlana Kuznetsova in the quarterfinals.
