Serena Williams withdrew injured on Friday from what would have been a showcase semi-final at the against Ash Barty at the Yarra Valley Classic.
The Melbourne tune-up is among a handful of events being contested prior to Monday’s start of the Australian Open.
The clash between current and former No. 1 players was set up after Barty advanced 7-5, 2-6, 10-4 over American Shelby Rogers and Williams defeated compatriot Danielle Collins a 2019 Open semi-finalist – 6-2, 4-6, 10-6.
WTA matches are being played with match tiebreakers instead of third sets after a day was lost on Thursday due to emergency COVID-19 testing of more than 500 players and staff after a positive virus test at the main player hotel by a security worker.
Top seed Barty received a walkover into the final, where she will play the winner from another former No. 1 Garbine Muguruza or Czech Marketa Vondrousova.
