Aryna Sabalenka's Cincinnati Open title defense is over. The World No. 1 was eliminated by Elena Rybakina in the quarterfinals Aug. 15.

Elena Rybakina was all business against Aryna Sabalenka this time as the No. 9 seed routed the top-seeded Belarusian 6-1 6-4 in just an hour and 14 minutes of play to reach the Cincinnati Open semifinal.

Twice down break point while two games from victory against world No. 1 Aryna Sabalenka, Elena Rybakina stepped up to serve. She had let victory slip through her fingers against Sabalenka two months earlier in Berlin, squandering four consecutive match points in a third-set tiebreak. She had suffered close losses from winning positions all year.
