Serena Williams announced that she will retire from tennis this year. The 40-year-old says she will "evolve" away from the sport "to other things that are important to me" after the US Open in September.
Williams won 23 Grand Slam titles, second only to fellow American Margaret Court, who retired in 1977. She has won more titles in the professional era than any other woman or man. Serena won the French Open three times between 2002 and 2015, as well as seven Wimbledon titles - most recently in 2016.
Williams also won four Olympic gold medals and became the first tennis player to achieve a Grand Slam in both singles and doubles, where she played alongside her older sister, Venus.
In an interview with Vogue, Williams said she will focus on her family and business interests. "I've never liked the word pension. It doesn't seem like a modern word to me," she added. "This sport has given me so much. I love to win. I love to battle. I love to have fun."
Williams is widely regarded as one of the greatest tennis players of all time. She is the highest-paid female athlete of all time.
