A blistering Melbourne heatwave 2026 reached dangerous peaks on Tuesday, forcing Australian Open officials to trigger the Extreme Heat Policy as temperatures soared to a stifling 45°C (113°F). While the sweltering conditions suspended play on outside courts, the action inside Rod Laver Arena remained red-hot. Defending champion Aryna Sabalenka ended the fairytale run of 18-year-old American prodigy Iva Jovic, while Alexander Zverev overcame a fierce challenge from rising U.S. star Learner Tien under the safety of the closed roof. As the Australian Open 2026 results trickle in, the quarterfinals have set the stage for a dramatic finish to the tournament.
Sabalenka Ends Jovic’s Historic Run in Straight Sets
World No. 1 Aryna Sabalenka proved too powerful for teenage sensation Iva Jovic vs Aryna Sabalenka, taking the quarterfinal match 6-3, 6-0 in just under 90 minutes.

The 18-year-old American, who had already upset Jasmine Paolini and Yulia Putintseva to reach the last eight, pushed the Belarusian hard in the opening set.

She played incredible tennis and pushed me to a higher level.”
For Jovic, the loss marks the end of a breakout tournament that will see her ranking skyrocket into the top 20. The American tennis stars 2026 narrative is far from over, with Jovic cementing herself as a future major contender.

While fans outside sought shelter and hydration stations were overwhelmed, the controlled environment indoors allowed the tennis quarterfinals today to continue without interruption.
