Williams sisters return to U.S. Open doubles after four years

In the U.S. Open, Serena Williams and Venus Williams are competing together in doubles for the first time in four years. They will face Maya Joint and Hao-Ching Chan, who recently defeated Serena at Wimbledon. This comeback follows Serena's hiatus from tennis, during which she focused on family. Their participation is significant as they have previously won the U.S. Open doubles title twice.
