Sources: 151. Developments: 5. The Cincinnati Open has experienced significant upsets in both the men’s and women’s draws. In the women’s singles, world number one Aryna Sabalenka was defeated by 20-year-old Czech player Sara Bejlek, 7-6(7), 6-4. Bejlek, ranked 35th, overcame substantial leads held by Sabalenka in both sets to secure her first win against a top-10 opponent. This loss puts Sabalenka’s world number one ranking at risk, as Elena Rybakina could claim the top spot if she reaches the final. In the men’s draw, top seed Alexander Zverev was eliminated by American Tommy Paul. Following rain delays, Paul staged a comeback to win 4-6, 7-6(6), 6-4, saving a match point in the second set. Paul is set to face Flavio Cobolli in the quarterfinals. Other notable results include Arthur Fils defeating Alex de Minaur to reach his fifth Masters 1000 quarterfinal, and Lorenzo Musetti advancing after a victory over Jaime Faria.
