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

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.

Miryni was asked to join the Sabalenka team by her head coach Anton Dubrov. Miryni had been an accomplished serve-volley player and the thinking is that Sabalenka should be able to use her skills coming off her big serve by volleying more.
