Sabalenka vs Uchijima Prediction
Best prediction: Aryna Sabalenka wins 2-0.
Sabalenka enters the matchup with overwhelming advantages in serve quality, return pressure, first-strike power and recent hard-court performance.
The world No. 1 owned a 36-6 overall record and a 23-1 hard-court record entering the North American summer swing. She had dropped only four sets across those 24 hard-court matches.
Those numbers make this a difficult opening assignment for Uchijima. The Japanese qualifier must absorb one of the heaviest combinations of serving and groundstroke power on the WTA Tour while also finding a way to protect her own second serve.
Sabalenka should establish control with aggressive returns and force Uchijima to defend from behind the baseline. Once shorter balls begin appearing, Sabalenka can end points before Uchijima has an opportunity to turn the match into a longer physical contest.
Our projected score is 6-3, 6-2.
Sabalenka may need several games to adjust to the Toronto conditions after her first-round bye. Uchijima has already played a main-draw match and should enter with a clearer sense of the court speed. That situational advantage may help her remain competitive early, but it should not erase the wider difference between the players.
Match-specific game, set and player markets may continue moving before the first ball. Readers can monitor the latest tennis lines and market movement throughout the afternoon.
Sabalenka Dominated Their Previous Meeting
Sabalenka and Uchijima have met once before, in the second round of the 2024 French Open.
Sabalenka won that match 6-2, 6-2 in 62 minutes. Uchijima stayed level through the opening five games before Sabalenka began attacking her second serve and controlling the baseline exchanges.
The statistical separation was considerable.
Sabalenka won 76% of her first-serve points, 72% of her second-serve points and saved all four break points she faced. She also produced 25 forehand winners and won 11 of 14 points at the net.
Toronto’s hard courts should favor Sabalenka even more than the clay in Paris. The quicker surface rewards her ability to take the ball early, shorten points and create immediate pressure with the first two shots of a rally.
The previous match does not guarantee an identical result. Uchijima has gained experience since 2024 and enters Toronto after winning her opening match in straight sets. It does, however, show how difficult it is for her to maintain neutral court position once Sabalenka finds her range.
That matchup history supports Sabalenka in straight sets rather than merely predicting that the favorite advances.

Can Moyuka Uchijima Produce an Upset?
Uchijima’s path begins with surviving the opening service exchanges.
She cannot afford to let Sabalenka settle into repeated 15-0 and 30-0 service games. If the favorite moves rapidly through her own holds, Uchijima will face constant scoreboard pressure and may begin forcing low-percentage shots during her service games.
The qualifier needs to vary the height and direction of her groundstrokes, extend rallies when possible and make Sabalenka hit additional shots. She also needs a high first-serve percentage because second serves will give Sabalenka immediate opportunities to attack.
Uchijima showed resilience against Bucsa. She won in straight sets despite trailing 4-1 in the second set, closing the match by taking five consecutive games.
That comeback demonstrates why Sabalenka cannot treat the matchup as a formality. Uchijima has already competed in Toronto conditions and arrives with nothing to protect as a major underdog.
Her upset path still requires several things to happen at once:
- Sabalenka must struggle with her first-serve percentage or timing.
- Uchijima must avoid giving away early breaks through second-serve pressure.
- Longer rallies must become frequent enough to disrupt Sabalenka’s first-strike rhythm.
- Uchijima must convert the limited break opportunities she creates.
- Sabalenka’s unforced-error count must remain elevated for more than one set.
That combination is possible, but the 95% Polymarket assessment reflects how narrow the path appears.
Aryna Sabalenka Chances on Polymarket
Polymarket displayed Sabalenka at a 95% implied probability in the active match-winner market on Tuesday afternoon.
The contract had approximately $39,200 in volume and $96,000 in liquidity, giving it considerably more activity than many early-round tennis markets.
A displayed probability is not always the exact price available for an immediate purchase. Polymarket’s headline number reflects information from the order book, while the executable price depends on the available Yes and No orders when a participant enters the market.
That distinction matters when a player is priced near certainty.
At a 95-cent entry, a Sabalenka contract would return only five cents in gross profit if she advances. The entire 95-cent purchase amount remains at risk if Uchijima wins.
Market assessment: Pass at a 95% probability.
Our prediction strongly supports Sabalenka, but the market already reflects nearly all of that advantage. Correctly identifying the likely winner does not automatically make the available contract attractive.
Uchijima’s side offers a much larger potential return, but a low contract price is not enough to establish value. A participant would need evidence that her actual victory probability is materially higher than the market indicates.
This is the same distinction that applies across other active Polymarket sports contracts. Our previous look at Cavaliers vs Knicks Polymarket movement showed how market expectations can change rapidly around new information and game conditions.
Sabalenka’s WTA Toronto Title Chances
The tournament-winner market presents a different question from Tuesday night’s match.
Polymarket displayed Sabalenka at 20% to win the entire WTA Toronto title. That contract had attracted approximately $7,800 in volume with $54,300 in liquidity.
A one-in-five championship probability is much less extreme than her 95% match assessment. Sabalenka must win several matches against a deep WTA 1000 field, so the outright contract carries substantially more uncertainty.
Her case begins with the surface.
Sabalenka’s 23-1 hard-court record confirms that Toronto conditions suit her power, serve and aggressive court positioning. She has also reached the National Bank Open semifinal once and entered this event with a 9-6 career tournament record.
Toronto remains the major North American hard-court event she has not won. Her draw and current form make her a legitimate title candidate, but a field containing Elena Rybakina, Jessica Pegula, Iga Swiatek, Coco Gauff and Mirra Andreeva prevents any player from carrying overwhelming championship certainty.
Tournament lean: Sabalenka is a leading contender, but wait for an executable price before taking a position.
A strong performance against Uchijima could shorten the title contract. A difficult three-set match or visible serving problems could move it in the opposite direction.

How the Polymarket Match Contract Resolves
The match contract resolves according to which player officially advances from Sabalenka vs Uchijima.
If the match begins but is not completed because of a retirement, default or disqualification, the contract normally resolves to the player who officially advances.
A pre-match walkover is treated differently from a match that begins and ends through retirement. Participants should read the complete Rules section on the individual contract before purchasing either outcome.
The match is scheduled for Tuesday night, but weather, earlier matches or tournament operations can affect the start time. Refresh the order of play and the contract immediately before entering a position.
