The mighty Williams sisters — Venus and Serena — won the women’s doubles title at the Austrlian Open for the fourth time on Friday after beating Zimbabwe’s Cara Black and America’s Liezel Huber 6-4, 6-3 in the final.

Venus and Serena are the reigning Aussie Open champs, having beaten Slovakian Daniela Hantuchova and Japanese Ai Sugiyama in last year’s women’s doubles finale. The super sisters now own 11 major doubles titles, three of which came last year.
