Janice Tjen and Tereza Valentova kicked off Day 3 of the Australian Open with a pair of stunning upsets over seeded players, reaching the second round. Valentova first stunned No. 30 seed Maya Joint in straight sets, a feat matched by Tjen when she defeated No. 22 seed Leylah Fernandez moments later. These victories were particularly notable given their recent success against seeded opponents at other Grand Slams. Tjen's win against Fernandez was especially impressive, as she secured it with an impenetrable first serve, winning 100% of her first-serve points in the opening set. This set the tone for her eventual 6-2, 7-6 (1) victory in 1 hour and 43 minutes. The win sets up a second-round meeting with a former Grand Slam champion, either Karolina Pliskova or Sloane Stephens. Tjen's triumph marks her second Grand Slam win and her first at the Australian Open, making her the first Indonesian player to win an Australian Open main-draw match since Yayuk Basuki in 1998. Basuki reached the fourth round that year. Valentova's victory over Joint was her third Grand Slam main-draw win, showcasing her growing prowess on the tour. These upsets were just the beginning of a thrilling day of tennis at the Australian Open, with more surprises and exciting matches to come.
