Mirra Andreeva defeated Donna Vekic 4–6, 6–3, 6–0 in the first round of the Australian Open on hard court on 19 January 2026, confirming her status as the heavy pre-match favourite at odds of 1.12 to Vekic's 6.04. After dropping the opening set, Andreeva seized control with a commanding second set and then dismantled Vekic in the third, allowing just three games. The Croatian's inability to sustain pressure in the opening frame proved costly, as Andreeva's adjustment and dominance in the closing stages demonstrated the gulf in form between the two players. The result underscores Andreeva's current standing as a top-tier player on the WTA circuit and her credentials as a genuine contender in Melbourne.
