Top-seeded Aryna Sabalenka continued her impressive form at the Australian Open on Sunday, defeating Canadian rising star Victoria Mboko 6-1, 7-6(1) in the fourth round. The victory propels the world No. 1 into the quarterfinals as she chases her third title in Melbourne.
A Tale of Two Sets
The match at Rod Laver Arena began with Aryna Sabalenka in full command. Utilizing her signature heavy serve and aggressive baseline play, she dismantled the 19-year-old Mboko in the opening set, closing it out in just 30 minutes.
However, the dynamic shifted in the second set. Victoria Mboko displayed remarkable grit, rallying from a 1-4 deficit to break Aryna Sabalenka’s serve and save match points.
The Canadian teenager forced the set into a tiebreak, showcasing a competitive spirit that challenged the veteran champion. Despite the pressure, Aryna Sabalenka tightened her game when it mattered most, dominating the tiebreak 7-1 to seal the victory in one hour and 26 minutes.
Shattering Records
With this win, the 27-year-old Belarusian extended her streak of Grand Slam consistency, booking her place in a 13th consecutive major quarterfinal.
Perhaps more impressively, Aryna Sabalenka set a new Open Era benchmark for composure under pressure. Her tiebreak victory marked her 20th consecutive tiebreak win at major tournaments, eclipsing a record previously associated with Novak Djokovic.
Looking Ahead
While Victoria Mboko exits the tournament, her performance was a breakthrough, marking her first appearance in the fourth round of a Grand Slam. Her ability to challenge the top seed has been noted as a significant sign of progress for the young Canadian.
Aryna Sabalenka now turns her attention to the quarterfinals, where she will face 18-year-old American Iva Jovic. As another teenage talent looks to challenge the established order, Aryna Sabalenka’s quest for a third 2026 Australian Open crown continues.
