On the 23rd local time, former world queen Swiatek missed the opportunity at the end of the game, and after a fierce battle of 3 sets and 10 sets, he was upset by the difficult American 19th seed Kaess. So far, Poland's second seed has lost 7:5, 4:6, 6:7 (8:10), and still missed the Australian Open women's singles final in her career.

The 29-year-old, who has been in fine form of late, has extended her winning streak to 11 matches since winning Adelaide two weeks ago and is the first dark horse to reach Melbourne Park's Women's Singles final, where she will take on defending champion Sabalenka on Saturday, with the Belarusian top seed on her 20-match winning streak as she prepares to challenge for a treble in women's singles. It is worth mentioning that Sabalenka also has the upper hand with 4 wins and 1 loss against Kees in the past. Kass reached the 2017 US Open Women's Singles final, but lost in straight sets to compatriot Stephens, and now she is back in a Grand Slam Women's Singles final for the first time in eight years.

In the semifinals of the 2025 Australian Open, she overcame the disadvantage of losing the first set, regained her strength, and resolved the final point of the match at 5:6 in the third set, although Kass struggled to catch up in the deciding set 10, but finally withstood the pressure and fought back from 7:8 to become the winner of this fierce battle of 2 hours and 35 minutes. Swiatek, on the other hand, has risen and then declined, stopping in the top four of the Australian Open for the second time since 2022.
