American tennis star Madison Keys completed a huge comeback victory over World No. 2 Iga Swiatek in Thursday's Australian Open semifinal to set up a final matchup vs. World No. 1 and reigning champion Aryna Sabalenka.

With women’s tennis on the verge of an epic showdown between its top two players with the Australian Open title on the line, Keys, the 29-year-old American, crashed the party. She stormed back against Iga Swiatek to win their semifinal 5-7, 6-1, 7-6 (10-8)

Swiatek will face No. 19 Madison Keys of the U.S. on Thursday night for a berth in the final. The other women’s semifinal is No. 1 Aryna Sabalenka, the two-time defending champion, against her good friend, No. 11 Paula Badosa.
