Alex de Minaur vs Andrea Guerrieri Prediction, Odds & Best Bet - September 2, 2026

Andrea Guerrieri moneyline +1500 at DraftKings is the play. This is not a claim that Guerrieri is more likely than Alex de Minaur to win; de Minaur is priced as the overwhelming favorite for clear reasons. The case is that Guerrieri's projected chance of pulling the upset is slightly better than the probability demanded by +1500.

Guerrieri has a projected win probability of 7.7%, compared with a 6.3% market break-even rate. That produces a 1.4 percentage-point edge and 0.226 expected value per unit. The margin is positive but narrow, and the listed confidence is Low, so the price is essential to the position.

The underdog also arrives with tangible match preparation. Guerrieri won all three of his listed qualifying matches, including two that went to deciding sets. He recovered from losing the second set against August Holmgren and from losing the opening set against Joel Josef Schwaerzler. He then completed qualifying with a straight-sets win over Aziz Dougaz. That progression supplies the competitive basis for taking a small chance on the upset rather than relying on the price alone.

Alex de Minaur owns the strongest profile in this matchup. The 27-year-old Australian is ranked No. 7 with 3650 ranking points, is listed at 6' 0" and 152 lbs, plays right-handed, and is in his 11th season. Those numbers explain both his -2500 moneyline and why Guerrieri remains a low-probability selection.

De Minaur does not need to outperform an even market expectation; the market already asks him to dominate. For the favorite, the decisive route is to prevent Guerrieri from settling into service games and to make the qualifier play from behind on the scoreboard. Guerrieri dropped sets in two of his three qualifying matches, so de Minaur has a clear opening if he can establish early return pressure and convert break points before the Italian finds rhythm.

The principal problem with backing de Minaur is not his supplied ranking or experience. It is the extreme moneyline cost. At -2500, there is very little tolerance for a rare poor match, while Guerrieri's +1500 price needs to succeed only more often than its 6.3% break-even rate. De Minaur is deservedly favored, but being the expected winner and being the preferred wager are different questions.

Andrea Guerrieri, also 27, is listed at 5' 11" and 165 lbs and plays left-handed. His recent results provide the clearest argument for the underdog. Guerrieri defeated August Holmgren 6-3 6-7 (4-7) 6-2, beat Joel Josef Schwaerzler 3-6 6-4 6-1, and then handled Aziz Dougaz 6-2 6-4 in the qualifying final.

Those scorelines reveal two relevant qualities. First, Guerrieri has already handled different match scripts. He responded after losing a tiebreak set against Holmgren and after dropping the opening set against Schwaerzler. Second, his final qualifying performance was his cleanest: he won in straight sets without needing another decider. That does not erase the jump to facing the No. 7 player, but it shows why his upset probability need not be treated as negligible.

Guerrieri's left-handed delivery also changes the geometry from the right-handed opponents de Minaur may otherwise encounter, although the supplied numbers do not establish a specific tactical advantage. Guerrieri still must protect his serve, avoid extended runs of return pressure, and create enough break-point chances to make de Minaur uncomfortable. The moneyline requires Guerrieri to finish the upset; simply extending sets or remaining within the available game spreads will not cash +1500.

The central contest is Guerrieri's recent match toughness against de Minaur's enormous ranking and experience advantage. Guerrieri has won three consecutive listed matches, but de Minaur brings a No. 7 ranking, 3650 points, and 11th-season experience into US Open Round 1. The underdog must turn his qualifying momentum into immediate resistance on serve and return.

Guerrieri cannot afford the kind of opening-set loss he experienced against Schwaerzler. Recovering from 3-6 against that opponent is encouraging, but falling behind de Minaur would create a much tougher scoreboard problem. Guerrieri's more useful template is the qualifying final against Dougaz, when he took control with a 6-2 opening set and closed 6-4. An early hold pattern and the first meaningful break-point opportunities would give +1500 a chance to become live.

De Minaur's task is the opposite: make Guerrieri's previous recoveries irrelevant by keeping sustained pressure on the Italian's service games. If de Minaur takes control of the return exchanges and denies Guerrieri cheap holds, the favorite's superior supplied standing should tell. Guerrieri needs competitive sets plus an outright finish; de Minaur only needs to prevent the qualifier from converting momentum into enough breaks to alter the match.

The moneyline market lists Andrea Guerrieri +1500 at DraftKings and Alex de Minaur -2500 at BetMGM. That is an appropriately lopsided market given de Minaur's No. 7 ranking and Guerrieri's status as a player coming through three qualifying rounds. Kingpin Editorial differs only at the margin: the projection gives Guerrieri 7.7%, above the 6.3% break-even threshold.

The other markets reinforce how dominant de Minaur is expected to be. Guerrieri is available at +9 (-107) and +9.5 (-130), while de Minaur is listed at -9 (-123) and -9.5 (+111). The match total is 28.5, with Over and Under both priced at -110.

Those alternatives separate two different opinions. Taking Guerrieri with a nine-game or 9.5-game cushion would ask only that he remain competitive. The featured moneyline instead says his outright chance is slightly underpriced. Because the projection edge is only 1.4 percentage points and confidence is Low, +1500 is the actionable number; a materially shorter return would require a fresh assessment.

A materially worse price on Andrea Guerrieri would change the wager. The case is constructed around +1500 and its supplied 6.3% break-even rate. If Guerrieri's moneyline shortens enough to remove the gap beneath the 7.7% projection, the underdog no longer offers the same mathematical case.

A retirement concern, schedule delay, or change affecting either Guerrieri or de Minaur would also require reassessment. Guerrieri's appeal depends on carrying his three-match qualifying run into Round 1, while de Minaur's price depends heavily on his No. 7 standing and ability to perform at that level.

On the court, de Minaur consistently controlling Guerrieri's serve would undermine the upset route. If Guerrieri cannot hold often enough to reach pressure points in sets, or if de Minaur denies him realistic break-point opportunities, +1500 becomes increasingly dependent on an improbable reversal. Conversely, Guerrieri holding comfortably and threatening de Minaur's serve early would validate the narrow pre-match edge.
