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 broke Huber’s serve to open the second set Friday and won the match when they again broke Huber, ending it on Serena’s winning reflex volley.

The Williams sisters won the Australian title for the first time in 2001 and added championships in 2003 and last year.

It was the 11th time the Williams sisters have combined for a Grand Slam doubles title.
