World No.1 Aryna Sabalenka is ready to flex her dominance once again as she faces Czech underdog Nikola Bartunkova in the quarterfinals of the 2026 WTA Berlin Ladies Open. The Belarusian powerhouse is heavily favored to cover the -5.5 games spread in what looks like a mismatch on grass.
Sabalenka cruised past Ekaterina Alexandrova 6-4, 6-4 in the round of 16, improving her grass record to 42-21 and firing seven aces while dominating on serve. The 2026 French Open run showed her relentless form, and she hasn’t dropped a set against players outside the top 50 all year.
Bartunkova, ranked No.62, pulled off a solid upset over Elise Mertens 6-1, 6-4 to reach her first Berlin quarterfinal. She’s 6-2 on grass this season and has shown fight with three top-20 wins in her career, including a notable victory over Belinda Bencic at the Australian Open. However, this marks her first-ever meeting against the current world No.1.
The gap in elite experience is glaring. While Bartunkova has been competitive in patches, Sabalenka’s serve, power, and court coverage have been nearly unstoppable. Experts predict the top seed will roll to the semifinals with a commanding straight-sets victory.
Bold Prediction: Aryna Sabalenka -5.5 Games
This matchup highlights Sabalenka’s quest to add another grass title to her résumé as she builds momentum toward Wimbledon. Bartunkova will look for any opening to make it competitive, but most expect the No.1 to deliver a statement performance.
Tennis fans are buzzing — will Sabalenka make it look easy, or can the Czech pull off a miracle? The Berlin grass is set for fireworks.
