[Methodology and sources](#methodology) Key takeaway Elena Rybakina beat Naomi Osaka in straight sets at the US OPEN. Court Shark's model gave Rybakina a modest edge before play, slightly stronger than the market consensus. ## The early read held Under the lights in New York, [Naomi Osaka](https://courtshark.ai/players/naomi-osaka-10211768) faced a rival who quickly took control of the court. [Elena Rybakina](https://courtshark.ai/players/elena-rybakina-10214981) kept the exchanges direct and finished with a 1-6 4-6 victory. The score was decisive. Osaka had arrived on a strong run, but Rybakina gave her little time to turn that recent confidence into sustained pressure. Court Shark's model had Rybakina at 59% before the match, while the opening market consensus placed Osaka at 47%. That gap was not huge, and the final score should not be read as proof that the matchup was certain. Still, the result followed the pre-match lean. Rybakina's higher standing and her recent success against Osaka made her the more convincing side, even with Osaka entering the tournament in sharp hard-court form. ### What the model expected, and what happened Article snapshot, Sep 8, 2026 · Not live Elena Rybakina won 6-1 6-4\. The model had made them the favorite. __Pre-match model probability and the result__ | Player | Model before the match | Result | | -------------- | ---------------------- | ------ | | Naomi Osaka | 41% | Lost | | Elena Rybakina | 59% | Won | Source: Court Shark model and match data.View data table ## Similar form, different context Both players came to New York with an 8-2 record from their latest matches. Their hard-court record over the same span was also 8-2\. The recent results gave this meeting a balanced feel. Each player was on a three-match winning run and had stayed active without carrying a long absence into the tournament. The rankings supplied the sharper contrast. Osaka was No. 603, while Rybakina was No. 4\. Osaka's position did not erase her current form, and it also did not erase her history as a player who has reached the top of the rankings. Yet a comeback ranking can leave uncertainty around how a player will hold up against an opponent established near the front of the game. Rybakina entered with a different kind of evidence behind her. Her recent record showed that she was winning now, rather than relying only on an earlier reputation. She had also played recently enough to arrive fresh, with no sign of a long pause before the match. Osaka had the same broad advantage in freshness, which made the result more about the matchup than about one player having a clearer schedule. ## Toronto provided a useful clue Their previous meeting came in Toronto on hard courts, making it a useful reference for a rematch at the US OPEN. Rybakina held the 0-1 head-to-head advantage after winning 4-6 7-6(5) 6-4\. That match was much tighter than the New York result. Osaka had found a way to make Rybakina work across a full contest, even though Rybakina ultimately escaped with the win. The Toronto result did not settle the rematch. A close contest can point in different directions, especially when both players have arrived with strong recent records. But it did establish that Rybakina had already solved this opponent on the same surface. She had handled Osaka's power and found enough answers when the match became tense. New York produced a cleaner version of that pattern. Osaka did not get the extended battle that had kept Toronto competitive. Rybakina took the initiative early and never allowed the contest to develop into another narrow finish. That distinction helps explain why the model's preference looked reasonable before play, even though the market still gave Osaka meaningful support. ## What the model says The model gave Osaka a 41% chance and Rybakina a 59% chance before play. It favored Rybakina, but it did not present Osaka as an opponent without a route through the match. Osaka's recent hard-court results supported the case for resistance. The outcome instead showed how quickly a close pre-match projection can turn into a one sided score once one player controls the early exchanges. The market consensus had Osaka at 43% and Rybakina at 57%. That was close to the model's view, although the model leaned a little more firmly toward Rybakina. The market had begun with Osaka at 47% and then moved toward Rybakina. The shift reflected growing agreement that the higher-ranked player had the stronger pre match case. Rybakina moves into the quarterfinals after a performance that left few openings for Osaka. Her next round brings a fresh opponent and a different set of returning patterns. That match will ask whether she can repeat the same control against a player who has not recently faced her in Toronto or New York. ## Explore this matchup Compare both players side by side: recent results, head-to-head and the model. ### Player comparison Article snapshot, Sep 8, 2026 · Not live Each measure on the same scale: recent wins, wins on this surface, head-to-head wins and the model's chance. __Player comparison__ | Measure | Naomi Osaka | Elena Rybakina | | --------------------- | ----------- | -------------- | | Wins, last 10 matches | 80% (8-2) | 80% (8-2) | | Wins, last 10 on hard | 80% (8-2) | 80% (8-2) | | Head-to-head wins | 0% (0-1) | 100% (1-0) | | Model win probability | 41% | 59% | Source: Court Shark model and match data.View data table ### Head-to-head by surface Article snapshot, Sep 8, 2026 · Not live Naomi Osaka and Elena Rybakina have met once.

Model estimates and observed results The win probabilities come from the Court Shark match model, trained on completed ATP and WTA matches. A probability says how often a player in this position wins, not that one result will happen. The model's number for a match is recorded before play and never changed afterwards, so it can be checked against the result. Sources and citations Results, scores, rankings and serve statistics come from the Court Shark match database. The market consensus is the pre-match price for each player converted to a probability. Figures in this article are a snapshot taken when it was written. Limitations Serve and return rates count only matches with full serve statistics, which are sparser for Challenger and lower-level events, and the tour average they are compared with covers every year on record. Head-to-head records count every meeting with a recorded winner, walkovers and retirements included. Charts and tables are a snapshot and do not update after publication.
