World No. 1 Aryna Sabalenka suffered a stunning upset at the Cincinnati Open, falling in straight sets to Czech teenager Sara Bejlek. The unseeded 35th‑ranked Bejlek outplayed the four‑time Grand Slam champion, winning 7-6 (7-5) 6-4 in just under two hours and securing a place in the quarter‑finals of the WTA 1000 tournament.
Bejlek displayed remarkable resilience, clawing back from a 5-1 deficit in the first‑set tiebreak before turning the tables in the second set, where she erased a 4-1 hole to claim her maiden victory over a top‑10 opponent. The 20‑year‑old from Znojmo was visibly overwhelmed by the achievement, telling the crowd, "I feel incredible. I lost totally my words. I just kept believing and that was the key today." Sabalenka’s early exit opens the door for Elena Rybakina to overtake the world No.
1 spot should she reach the Cincinnati final, adding extra intrigue to the remaining matches. In the women’s draw, Coco Gauff continued her strong run, dispatching 22nd‑seeded Czech Marie Bouzkova 6-3 6-2 in a brisk one‑hour‑33‑minute match. The fourth seed will now meet Ukraine’s rising star Marta Kostyuk in the quarter‑finals, where a place in the semi‑finals awaits the winner.
On the men’s side, Tommy Paul produced a dramatic comeback against top seed Alexander Zverev. After dropping the first set 4-6, Paul fought back to win a tense second‑set tiebreak 8-6 before clinching the decider 6-4. The match was interrupted by a nearly 90‑minute rain delay, during which Zverev lost momentum.
Paul saved a match point, leveled the score, and then surged ahead, winning four consecutive games to seal his first quarter‑final appearance at Cincinnati. He will face Italy’s Flavio Cobolli next. American Frances Tiafoe added a milestone to his résumé, delivering a composed performance to upset second seed Félix Auger‑Aliassime 6-4 6-4.
The 28‑year‑old’s victory propelled him into his second Masters 1000 quarter‑final of the season, following a similar run in Miami. This marks the first time Tiafoe has reached multiple Masters 1000 quarter‑finals in a single year. He now prepares for a clash with Italy’s Lorenzo Musetti, who advanced after a 7-5 6-2 win over Jaime Faria. France’s Arthur Fils also made his presence felt, overcoming fifth seed Alex de Minaur 6-3 6-4.
Meanwhile, the highest‑ranked American still in the men’s draw, Taylor Fritz, defeated Australian Christopher O'Connell in straight sets, 6-4 6-3, keeping his hopes alive for a deep run. Perhaps the most surprising storyline came from Argentina’s Thiago Tirante, who eliminated Novak Djokovic in the second round. Tirante’s 5-7 6-4 6-4 triumph over Czech Jakub Mensik earned him a spot in the quarter‑finals, making him the first Argentine to reach that stage in Cincinnati since Juan Martín del Potro’s 2018 campaign.
