14 years after they played each other in their first Australian Open final, sisters Venus and Serena Williams are to do battle once more.

The American duo will meet each other in a Grand Slam final for the eighth time. It will be the first time the sisters have played in a final since Serena won at Wimbledon in 2009.

Venus was the first sister to reach the final. She lost the first set on a tiebreak to CoCo Vendeweghe, but fought back to win the final two sets, 6-2, 6-3.

The older Williams has not reached a Grand Slam final since the 2009 Wimbledon loss to Serena. Her only appearance in the Australian Open final was to her younger sister n 2003.

While Venus battled to reach the decider, Serena had an easier time, beating Croatia's Mirjana Lucic-Baroni in less than an hour. The World #2 won 6-2, 6-1.

A win for Serena on Sunday will earn her a 23rd Grand Slam title, beating Steffi Graf's record in the Open era.

The sisters have met competitively on 27 occasions, with Serena leading the head-to-head 16-11. In Grand Slam encounters, Serena leads 8-5. In Grand Slam finals, Serena leads 5-2.

Saturday's match will also make history. Whichever player wins, will become the oldest Grand Slam winner in the Open era.
