The Williams sisters have claimed their third doubles gold medal at the Olympic Games.
Serena and Venis combined to beat the Czech duo Andrea Hlavackova and Lucie Hradecka 64 64 in the final on Sunday on Centre Court.
The sisters also won the doubles gold medal in 2000 and 2008. In the process, the sisters became the first players, male or female, in tennis history to win four Olympic gold medals.
Serena is also now the only player in tennis history to win the career golden slam – all four majors and the Olympics – in both singles and doubles.
The Williams broke serve in the opening game of the match and then held on to their serve throughout the opening set in 51 minutes.
They broke once again in the middle of the second set and completed the win in an hour and a hlaf.
