H3: Sabalenka’s perspective
In her on-court interview Sabalenka praised Mboko’s fight and highlighted how the Melbourne sun affected serving on one side of the court. “She pushed me really hard today,” Sabalenka said. “The sun goes right into your serve point… It was tricky. But I was just focusing staying in the moment, playing point by point.”

H2: Mboko’s rise and what she showed
At 19, Mboko has moved quickly through the WTA ranks and showed why she was named Newcomer of the Year. Facing the world No. 1 in Rod Laver Arena for the first time, she displayed aggressive serving and resilience to pull the second set into a tiebreak. Despite the loss, her ability to claw back from 4-1 and test Sabalenka will be a confidence booster for the young Canadian.

H2: What’s next — a teenage test for Sabalenka
Sabalenka will face U.S. No. 29 seed Iva Jovic in the quarterfinals. Jovic reached her first Grand Slam last eight by dismantling Yulia Putintseva 6-0, 6-1. Another meeting with a rising young opponent sets up an intriguing contest: Sabalenka’s experience and tiebreak poise against Jovic’s recent dominant run.

H4: Bottom line
Sabalenka survived a stern test from an in-form teenager to advance in Melbourne, extending her impressive Grand Slam tiebreak streak and keeping her run toward another major title alive.
