Ann Li beats Sabalenka as form challenges reputation
Ann Li's Wuhan comeback beat a strong favorite, but her recent form showed a more competitive opponent than the ranking gap suggested.
Ann Li recovered from a set down to beat Aryna Sabalenka in Wuhan, turning competitive recent form into an upset. Court Shark had given Sabalenka an 84% chance before the match.
A deciding tiebreak changes the story
The deciding tiebreak in Wuhan went to Ann Li, leaving Aryna Sabalenka with another defeat after her Beijing exit. Reputation wasn't enough. Sabalenka took the opening set, but Li won the next and carried the contest through a deciding set that required a tiebreak. The result puts Li's recent competitiveness at the center of a match that looked heavily tilted toward her opponent before play began.
Court Shark gave Li a 16% chance, against 84% for Sabalenka. Those estimates describe an upset, rather than a result that should have been expected from the available records before the match started. Li still had a credible recent record, and the difference in form was much narrower than the difference in their estimated chances. That distinction matters when assessing what happened.
Sabalenka's opening set finished 6-3, and Li answered with 6-4. The progression shows a favorite who established an advantage but could not close the match, rather than an underdog who controlled it from the start. The final tiebreak settled a contest that remained unresolved deep into the deciding set.

The recent results were closer than the ranks
Sabalenka arrived ranked No. 2, while Li was No. 31. The ranking gap was clear. Yet their recent results offered a closer comparison, with both players coming to Wuhan after winning more often than they had lost. Li's position made her the underdog, but her results did not describe a player struggling to find wins against tour opposition.
Their recent records were 8-2 for Sabalenka and 7-3 for Li. Sabalenka's run included wins over Taylor Townsend and Jessica Pegula at the US Open, before losses to Elena Rybakina there and Nikola Bartunkova in Beijing. Li had beaten Donna Vekic at the US Open and Belinda Bencic in Beijing. These were concrete reasons to take her current form seriously without pretending the players had equivalent records.
Li had played 4 matches in the preceding fortnight, compared with Sabalenka's 2. She also entered on a winning run, while Sabalenka's previous match had ended in defeat. More recent competition can mean greater continuity, though it does not establish a cause for this result. The useful observation is that Li arrived with match practice and wins behind her.

History favored Sabalenka, but left room
Sabalenka led the head-to-head 3-0 before Wuhan, with every meeting on hard courts. History backed the favorite. It gave Li no previous victory in this matchup to lean on, even though her recent results elsewhere were encouraging. That record strengthened the case for Sabalenka beyond the difference in ranking and made Wednesday's reversal a meaningful break from their earlier meetings.
Their latest meeting had come in Miami, where Sabalenka won 7-6(5) 6-4. The opening tiebreak is an important detail because it shows that a straight-sets result can still include a set decided by a narrow margin. It does not prove Li was about to turn the matchup around. It does prevent the earlier result from being read as uninterrupted separation between the players.
Wuhan supplied a different finish after Sabalenka again put herself ahead. Li recovered from losing the opening set and won a deciding tiebreak, changing the outcome without making the earlier meetings irrelevant. The sensible reading is that Sabalenka had earned favorite status through past results, while Li found a way to beat her this time. Neither conclusion requires rewriting the entire rivalry.

Hard courts gave the favorite a real edge
The recent hard-court records matched the overall form comparison: Sabalenka was 8-2 and Li was 7-3. Both were winning regularly. That matters because Wuhan's surface offered no obvious reason to dismiss Li's recent success as unrelated to the conditions. Her challenge was facing an opponent with a stronger longer record on the same surface, rather than adapting to unfamiliar ground.
Across the broader hard-court sample, Sabalenka's record was 32-5 against Li's 17-15. This is where the distinction between recent form and established performance becomes more pronounced, even without relying on ranking as a shortcut. Sabalenka had sustained a much higher rate of winning over that stretch. Li's recent run was better than her broader record, which made her current level particularly relevant to this meeting.
Sabalenka held serve in 84% of her service games in the hard-court sample, compared with Li's 73%. Those figures support the pre-match case for the favorite, but they are not a description of serving in Wuhan. Without match-specific serve figures, the result cannot be assigned to a particular technical failure. The score establishes Li's comeback, not its point-by-point cause.
What the model says
Before the match, Court Shark gave Sabalenka an 84% chance and Li a 16% chance. The favorite lost. A probability is an estimate rather than an outcome, and this result belongs to the less likely side of that estimate. Li's victory does not make the pre-match advantage imaginary, although it does show why even a strong favorite remains vulnerable in a competitive match.
The market consensus at the start had Sabalenka at 82% and Li at 18%. It agreed on the favorite while giving the underdog slightly more room than Court Shark did. The gap was small, so there was no major disagreement between the model and market about the likely winner. Both expected Sabalenka to prevail, and both left a chance for the result Li delivered.
Sabalenka's opening consensus was 83%, with the price moving 1 percentage point toward Li before play. That was a modest shift, not a reversal of expectations or a signal that the upset had become the likely outcome. More wins by Li against opponents of Sabalenka's level, or continued defeats for Sabalenka, would change the case for making Sabalenka such a strong favorite in another meeting.

Methodology and sources
How we build model estimates and where our information comes from.
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.
