Tennis: Williams sisters win Australian Open doubles title

Defending champions Serena and Venus Williams defeated Cara Black and Liezel Huber 6-4 6-3 to win the Australian Open women's doubles title on Friday, maintaining the partnership's perfect record in grand slam finals.

The second-seeded Williams sisters continued their dominance over Zimbabwe's Black and American Huber, overcoming a sluggish start under bright sunshine at Rod Laver Arena to win in 86 minutes and seal their 11th grand slam doubles title. (Reuters)
