[Methodology and sources](#methodology) Key takeaway Leylah Fernandez beat Mirra Andreeva in Singapore, extending a hard-court matchup pattern that the pre-match consensus had largely dismissed. Court Shark's model favored Andreeva, but gave Fernandez a far more credible chance than the market did. ## A quick exit in Singapore Fernandez drove a backhand deep into the court in Singapore and left Andreeva scrambling from the opening exchanges. [Mirra Andreeva](https://courtshark.ai/players/mirra-andreeva-10259799) arrived as the higher-ranked player, yet the first qualifying round ended with Fernandez winning 2-6 5-7\. The result was sharp. It also exposed how quickly a ranking gap can obscure a matchup issue. Andreeva had won seven of her previous ten matches, and her hard-court record over that span was identical. That form made her the obvious favorite in casual terms. But the result did not arrive from nowhere, because Fernandez had already shown that her game could disrupt Andreeva on this surface. Singapore became another reminder that recent overall form does not settle a specific pairing. ### What the model expected, and what happened Article snapshot, Sep 26, 2026 · Not live Leylah Fernandez won 6-2 7-5\. The model had made the other player the favorite. __Pre-match model probability and the result__ | Player | Model before the match | Result | | ---------------- | ---------------------- | ------ | | Mirra Andreeva | 64% | Lost | | Leylah Fernandez | 36% | Won | Source: Court Shark model and match data.View data table ## The head-to-head that mattered The overall head-to-head favored Andreeva 2-1 before this match. That was the number likely to draw the eye, especially beside her No. 5 ranking. It was also incomplete. Their only prior hard-court meeting belonged to [Leylah Fernandez](https://courtshark.ai/players/leylah-fernandez-10220367), leaving her with a 0-1 surface edge. That meeting came in Toronto on August 7, when Fernandez won 6-1 6-4\. The score gave the earlier match more weight than a close finish would have done. One match cannot become a rule. Still, it offered a specific warning that an overall series lead could mislead when the players returned to hard courts. ## Why the ranking gap misled Andreeva entered at No. 5, while Fernandez stood at No. 31\. That is a substantial separation, and rankings rightly shape expectations over a long season. This was a short format, though. A best-of-three match gives less time for a favorite to correct a poor start or solve an uncomfortable return pattern. Fernandez had reached as high as 13 in the rankings, so her current position did not describe an unknown opponent. She was also on a three-match winning run. Andreeva had played once in the previous 14 days, while Fernandez had played three times. Both players were fresh, but Fernandez brought more immediate match repetition into Singapore. ## Form pointed in both directions Both players brought a 7-3 record from their last ten matches. Their hard-court marks over that same window were also 7-3\. There was no broad form advantage to turn this into a simple story about one player arriving hot and the other slipping. The surface evidence was remarkably even. Andreeva came in on a one-match winning run after two days away from competition. Fernandez had the same two-day break, with momentum from her longer streak. Small details matter here. Fernandez had already beaten this opponent on hard courts and had more recent playing volume, which made the apparent gap between their rankings less decisive than it looked. ## A consensus too certain The market consensus put Andreeva at 76% before the match, after moving one point toward her from the opening view. Fernandez was assigned 24%. That consensus treated the ranking difference and Andreeva's recent results as overwhelmingly persuasive. The head-to-head trap was that the surface-specific record suggested a more complicated contest. Court Shark's view was less certain from the start. The gap between the model and consensus was 12 points on Andreeva, a meaningful difference in a match involving players with matching recent hard-court records. The result does not prove that the lower consensus view was destined to win. It does show why a single, broad head-to-head figure should never be read without checking where those meetings occurred. ## What the model says The model gave Andreeva a 64% chance and Fernandez a 36% chance before play began. The market consensus had Andreeva at 76% and Fernandez at 24%. Fernandez won the match, but the model still made Andreeva the favorite. Estimates can be reasonable and still lose on a given day. The final score, 2-6 5-7, shows Fernandez handled the match in straight sets. The model call would have changed with stronger evidence that the Toronto result was isolated rather than a repeatable hard-court matchup problem. Singapore instead added a second result pointing in the same direction, even as Andreeva's wider record remained stronger. ## Explore this matchup Compare both players side by side: recent results, head-to-head and the model. ### Player comparison Article snapshot, Sep 26, 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 | Mirra Andreeva | Leylah Fernandez | | --------------------- | -------------- | ---------------- | | Wins, last 10 matches | 70% (7-3) | 70% (7-3) | | Wins, last 10 on hard | 70% (7-3) | 70% (7-3) | | Head-to-head wins | 67% (2-1) | 33% (1-2) | | Model win probability | 64% | 36% | Source: Court Shark model and match data.View data table ### Head-to-head by surface Article snapshot, Sep 26, 2026 · Not live Mirra Andreeva and Leylah Fernandez have met 3 times.

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.
