Venus and Serena Williams won their fourth Australian Open women’s doubles title, beating Cara Black and Liezel Huber 6-4, 6-3.
The Williams sisters won the Australian title for the first time in 2001 and added championships in 2003 and last year. Black, from Zimbabwe, and Huber, a South African-born American citizen, won the 2007 title.
It was the 11th time the Williams sisters have combined for a Grand Slam doubles title.
Serena has 11 singles majors, also, and is hoping for a 12th in the Australian Open final on Saturday against Justine Henin.
Venus has also won a mixed-doubles title at the Australian Open — in 1998 with fellow American Justin Gimelstob.
