Serena Williams's record of victories is the most impressive in the history of tennis. Williams has won 23 Grand Slam singles titles, more than any other player in the Open Era, male or female. As of 2019, she has won every Grand Slam tournament in singles at least three times and in doubles at least twice, the year-end championships five times, and four Olympic gold medals, an all-time record for a tennis player. Twice, she has held all four Grand Slam tournament titles at the same time, and she has won more top-tier WTA tournaments than any other player. Williams has won more prize money than any other female player, winning over double the amount of the second-place player on the all-time money list.
