London - Serena Williams followed up her seventh Wimbledon singles title and record-equalling 22nd Grand Slam crown with victory in the women's doubles alongside sister Venus on Saturday.
The unseeded Americans defeated fifth seeds Timea Babos of Hungary and Yaroslava Shvedova of Kazakhstan 6-3, 6-4 to claim their sixth Wimbledon doubles title.
It was also their 14th doubles triumph as a team at the majors and their 22nd in 23 finals overall.
The sisters last lost a doubles final in 1999 in San Diego.
"It's awesome to win another doubles at Wimbledon," said Serena.
Venus said: "I never want to make a mistake. I don't want to let Serena down. She brought the energy from the singles on to the doubles court."
Serena and Venus hadn't played together for two years before this year but reunited as part of their build-up for the Olympic Games next month.
Earlier Saturday, Serena had defeated Angelique Kerber 7-5, 6-3 in the women's singles final.
