Unstoppable Serena Williams zeroed in on a record-breaking 23rd Grand Slam title Thursday by setting up an Australian Open final against her older sister Venus, as the siblings' dream came true.
The ruthless world number two proved one step too far for unseeded Croat Mirjana Lucic-Baroni, whose fairytale tournament was finally ended in a crushing 6-2, 6-1 defeat in just 50 minutes.
In swatting aside the 34-year-old, in their first meeting since 1998, Serena, 35, stayed on track for a seventh Australian title which would take her past Steffi Graf's Open-era record of 22 major wins.Only Venus stands in the way after the elder Williams rolled back the years to beat fellow American Coco Vandeweghe 6-7 (3/7), 6-2, 6-3 in the other semi-final. It opened another chapter in their eventful family history as they meet for their ninth Grand Slam final on Saturday, eight years after the last at Wimbledon in 2009. Serena won that one and holds a 6-2 advantage.
