Madison Keys, whose best showing at a major was getting to the title match at the 2017 U.S. Open, was a 3-6, 6-3, 6-4 winner against Elina Svitolina and is into her third semifinal in Australia. Using a new racket this season, Keys is on a 10-match winning streak, including a title at a hard-court tuneup event in Adelaide. Her run to the semifinals in Melbourne includes victories over two past runners-up at the Australian Open, Danielle Collins and Elina Rybakina. Keys’ past losses in the semifinals in Melbourne came against eventual champions Serena Williams in 2015 and Ash Barty in 2022.
