Madison Keys fought back from a set down on Thursday to shock Iga Swiatek and reach her first Australian Open final, where she will face two-time defending champion Aryna Sabalenka.

The 19th seed powered through a thrilling semi-final on a final-set tiebreak against the world number two 5-7, 6-1, 7-6 (10/8) after Sabalenka had earlier swept aside Paula Badosa in straight sets. (AFP)
