Aryna Sabalenka will square off against Victoria Mboko in the fourth round of the Australian Open in Melbourne on Saturday, January 24.
Sabalenka has been incredible over the past few years and is currently dominating the women's tour. With two titles already at this complex, she looks determined to secure a third.

Sabalenka vs Mboko Preview, Prediction
by Tudor Cosma
Aryna Sabalenka Betting Preview
While she trails Iga Swiatek in Grand Slam titles (4 to 6), Aryna Sabalenka dominates the circuit with her staggering consistency. She reaches finals almost every tournament, rarely suffering early-round exits. Her occasional modest performances typically only occur in the closing stages against fellow Top 10 players.
In almost all other matchups, Sabalenka is authoritative, winning the majority of her matches 2-0. Her strengths are multifaceted: she possesses one of the world's best serves and has drastically improved her second serve over the last few years. Once a vulnerability that sapped her confidence, it is now a stable and efficient weapon.
From the baseline, she is highly aggressive, striking the ball violently in search of winners. She places constant pressure on the return, allowing her to break serve with ease.
She enters 2026 in peak form, having already won the Brisbane title without dropping a single set. Here in Melbourne, she has won all her matches in straight sets, including a hard-fought 7-6, 7-6 victory over Anastasia Potapova, where she managed the tie-breaks perfectly.
Victoria Mboko Betting Preview
Victoria Mboko is a 19-year-old Canadian, currently ranked No. 16 in the WTA. She is at a career-high ranking, experiencing a meteoric rise.
A year ago, she was outside the Top 300; today, she is a star of the circuit and a potential future Grand Slam champion. Climbing over 330 ranking spots in 12 months is simply impressive.
For her age, Mboko shows remarkable maturity. She possesses massive baseline power and one of the most efficient serves in the WTA. Her mental resilience is equally notable; last year, she won the Montreal title at home, defeating champions like Coco Gauff, Elena Rybakina and Naomi Osaka while coming back from set deficits.
She started 2026 by reaching the final in Adelaide (losing to Mirra Andreeva) and has been excellent in Melbourne. In the third round, she survived a see-saw battle against Clara Tauson, showing great focus in the deciding set. Today, however, she faces her ultimate test against the World No. 1.
Sabalenka vs Mboko Predictions, Betting Analysis
In her third-round match against Potapova, despite the pressure and the length of the match, Sabalenka committed only two double faults.
In her previous rounds, she recorded only one against Tiantsoa Rajaonah and one against Zhuoxuan Bai.
While Mboko is a high-level opponent, Sabalenka’s current serve mechanics are very refined.
Given the likelihood of Sabalenka controlling the pace of the match, I expect her to keep her double faults to a minimum. My prediction is for Sabalenka to commit Under 3.5 double faults
Pick: Sabalenka Under 3.5 Double Faults
