Coco Gauff Enters US Open Third-Round Match as Heavy Favorite Against Cristina Bucsa

The match is scheduled for 1:30 p.m. ET on Arthur Ashe Stadium, with Gauff entering as the world No. 4.
The listed market prices make Gauff a -2,400 moneyline favorite and Bucsa a +1,567 underdog; Gauff is also favored by 6.5 games.
Tennis Abstract’s Aug. 31 Elo ratings placed Gauff at 2,126.9 overall and 2,086.8 on hard courts, compared with Bucsa at 1,700.8 overall and 1,677.0 on hard courts—a hard-court gap of roughly 410 points.
The Tennis Model V2 assessment says it does not provide a standalone win probability, edge percentage or expected-value claim for this match; its directional pick is based on a wide surface- and opponent-adjusted gap rather than treating the market price as automatic betting value.
The model specifically identifies Bucsa’s path to competitiveness as serving accurately and using controlled aggression to prevent Gauff from dominating extended rallies, while emphasizing return resilience and repeatable point construction in a best-of-three match.
Coco Gauff enters her US Open third-round match against Cristina Bucsa as an overwhelming favorite on September 5, with the world No. 4 listed at -2,400 on the moneyline. Tennis Abstract data shows Gauff holds a commanding 410-point hard-court Elo advantage over the Spanish player, ranked around No. 40, making her dominance the central storyline heading into the 1:30 p.m. ET matchup at Arthur Ashe Stadium.
Despite Gauff's overwhelming superiority in ratings and market pricing, some analysts see potential betting value in the total games line rather than backing Gauff's moneyline. Tennis Model V2 notes that Bucsa's path to competitiveness depends on precise serve placement and controlled aggression to keep rallies from becoming one-sided, while Gauff's dominant movement and return game should prove decisive in the best-of-three format.
Gauff's Elo rating stands at 2,086.8 on hard courts, nearly 410 points higher than Bucsa's 1,677.0 rating on the same surface, according to Tennis Abstract. This gap reflects Gauff's superior movement, early-contact returns, and ability to dictate play from the baseline. Bucsa has earned her spot by winning two prior matches, but faces an opponent who has spent years mastering the hard-court rhythm that defines the US Open.
Market makers agree. Gauff sits at -2,400 on the moneyline while Bucsa is a +1,567 underdog, a reflection of how heavily the sportsbooks expect Gauff to advance. The 6.5-game spread also underscores the expected margin, though analysts caution that Gauff's extreme moneyline odds leave minimal room for betting value on a Gauff win.
Bucsa cannot afford extended baseline exchanges. Tennis Model V2 identifies her best strategy as serving accurately and mixing in controlled aggression to shorten points before Gauff can impose her dominance. Return resilience and repeatable point construction will be critical in a best-of-three format where momentum can shift quickly if Bucsa wins a set.
The ranked-40 Spaniard has already shown enough court sense to reach the third round, but the gulf in Elo ratings suggests those wins came against lower-ranked opponents. Against Gauff's world-class return game and movement, Bucsa will need near-perfect execution to avoid a quick two-set loss.
While Gauff's moneyline pricing offers minimal value, some analysts suggest that betting the over on 17.5 total games presents a more interesting opportunity. Even in a dominant performance, Gauff will likely need multiple service games and hold situations that inflate the game count. Bucsa's ability to generate a few hold games and push at least one tiebreak could push the match toward 18 or 19 games.
Tennis Model V2 emphasizes that its directional assessment is based on the wide surface- and opponent-adjusted gap rather than treating Gauff's market price as automatic betting value. The model declines to claim a specific win probability or expected-value edge for a moneyline bet, signaling caution around Gauff despite her clear superiority.
