Kimberly Birrell: Kimberly Birrell’s fairytale run at the Brisbane International continues as she surged into her maiden WTA 500 quarterfinal after prevailing against world No. 35 Anastasia Potapova 7-6(2) 6-2.

The victory added to a scintillating start to 2025 for the 26-year-old, who defeated world No.8 Emma Navarro on Wednesday for her first top-10 win since she downed then-No.10 Daria Kasatkina at the 2019 Brisbane International.

"I’m so totally speechless. To play here is so special and to play well and have all of you guys behind me, it just means the world and I hope that I can keep going and make you guys proud," Birrell said.
