From Martina Navratilova to Venus Williams, some of tennis' greatest legends have extended their careers into their 40s.

The elder Williams was off the tennis tour for 16 months until making a comeback at a tournament in Washington last month, where she won one match each in singles and doubles. She hadn't competed anywhere since the Miami Open in March 2024, and had surgery for uterine fibroids later last year.

Venus Williams is back on the professional tennis tour at age 45 and will be returning to the U.S. Open next week for her first Grand Slam competition in two years.
