Wawrinka vs. Berrettini Prediction, Odds & Pick (8/31/2026)
Stan Wawrinka and Matteo Berrettini have played each other exactly once, at Wimbledon on June 30, and the scoreboard hid how close it was. All four sets went to a tie-break, the match ran four hours and 19 minutes, and Berrettini’s winning margin across the whole night was two games. Sportsbooks have looked at that and installed him as a -475 favorite who now has to win by five. The play is Stan Wawrinka +4.5 games at -105 at Caesars, a Lean Play at 0.75 units.
This is the last Grand Slam match of Wawrinka’s career. He is 41, ranked No. 127, and he is only in the draw because Patrick Kypson withdrew injured and the tournament handed the American’s wild card to him. Ten years ago he beat Novak Djokovic in the final on these grounds. The romance is real and it is also not the bet. The bet is narrower: whether two men who hold serve well finish inside a five-game gap.
USTA Billie Jean King National Tennis Center, Flushing Meadows, New York
Their Only Meeting Finished Two Games Apart
Berrettini took that Wimbledon first round 6-7(7), 7-6(16), 7-6(7), 7-6(5). Add the games up and it comes to 27-25. Every set reached 6-6, the second-set tie-break went 18-16 with Berrettini saving six set points along the way, and the ATP’s own match report described rock-solid serving from both men. Three of the four tie-breaks fell to Berrettini. That was the entire match.
The caveat is the surface. That was grass, and Monday is their first meeting on a hard court. A New York hard court gives the returner more time than Wimbledon does, which cuts in both directions: Berrettini collects fewer free points on serve, and Wawrinka’s flat backhand gets a bounce it can actually attack. Neither adjustment obviously widens a two-game gap into a five-game one.
The Serve Gap Is About Eight Points Wide
Berrettini has held serve on 86.1% of his service games at tour level this season; Wawrinka has held 78.2%. That eight-point gap is the whole case for laying games, and it is a fair one. It is also the size of gap that produces 6-4 sets rather than 6-2 sets, and a best-of-five built from 6-4 sets stops clearing a 4.5-game handicap the moment one set goes the other way.
The rest of the profile sits closer than an 84-place ranking gap suggests. Wawrinka has won more hard-court matches than Berrettini this season, the two are within a point of each other on ace rate, and Berrettini reached New York off a Cincinnati second-round loss to Jiri Lehecka. Three weeks before that he lost to Mariano Navone in Montreal, a result we wrote up at the time as a live upset spot.
| 2026 Season (ATP Tour Level) | Wawrinka | Berrettini |
|---|---|---|
| Service games held | 78.2% | 86.1% |
| Return games won | 14.9% | 16.3% |
| Ace rate | 9.2% | 10.0% |
| Double-fault rate | 2.9% | 2.5% |
| Tie-breaks won | 11-8 | 11-5 |
| Hard-court record | 6-8 | 4-4 |
Best-of-Five at 41, Third on Grandstand
Grandstand has no roof, so conditions matter here in a way they would not on Ashe. The National Weather Service forecast for Flushing on Monday is partly sunny, a high near 82, an east wind of 3 to 7 mph, and a 20% chance of showers before 5 p.m. Warm, still, and unlikely to be interrupted.
The age argument works against Wawrinka’s chances of winning more than against the handicap. Best-of-five is where a 41-year-old gets found out late, but the early sets are where a +4.5 ticket banks its cushion, and he stayed with this same opponent for four hours and 19 minutes in June. The winner also draws Novak Djokovic in the second round, which gives Berrettini every reason to want this short and Wawrinka every reason to make him earn it.
What -475 Actually Prices In
Ten books have priced this match and they agree almost completely. Berrettini’s moneyline runs from -445 to -500, an implied-probability spread of under two points. Every book that posts a games handicap has it on the same 4.5, with our side priced between +101 and -105. There is no disagreement to point at, which is why this is a Lean and not a bigger position.
Strip the vig out of the consensus moneyline and the market gives Berrettini roughly a 79% chance of winning the match. That is the market’s number rather than ours, and it looks reasonable. Winning a match and winning it by five clear games are two different questions, though, and the handicap price is where they come apart.
Where We Land: Wawrinka Stays Within Four
Take Wawrinka +4.5 games. The argument is not that a 41-year-old wild card beats a top-50 player over five sets. It is that these two produced a two-game match nine weeks ago, that Berrettini’s serving edge is eight points of hold rather than twenty, and that big servers push sets to 7-6 and 6-4. A straight-sets 7-6, 7-6, 6-4 win for Berrettini still cashes this ticket, and so does a repeat of the Wimbledon scoreline. Lean Play, 0.75 units.

Frequently Asked Questions
Four questions readers keep asking, answered with the numbers behind the call.
Who is favored in Wawrinka vs. Berrettini at the US Open?
Matteo Berrettini, heavily. He is priced between -445 and -500 across ten sportsbooks, which strips down to roughly a 79% market-implied chance of winning the match once the vig is removed. Wawrinka comes back at +320 to +360 depending on the book. The games handicap is a much closer question than the moneyline, and that is where our bet is.
Should I just take Wawrinka at +320 to win the match outright?
We are not making that bet. Wawrinka is 7-15 at tour level this season and 2-8 across his last ten matches, and Berrettini has climbed from No. 105 to No. 43 since May. The outright price is long for a reason. The +4.5 games handicap gives you most of the same story at a far shorter price, and it pays even when Berrettini wins.
What has to happen for Wawrinka +4.5 games to lose?
Berrettini has to win by five games or more across the whole match, counting every game in every set. A 6-4, 6-4, 6-4 scoreline is an 18-12 win, a six-game margin, and it beats the number. A 7-6, 7-6, 6-4 scoreline is 20-16, a four-game margin, and our ticket cashes. When these two played at Wimbledon in June, Berrettini won 27 games to 25.
Who does the winner of Wawrinka vs. Berrettini play next?
Fourth seed Novak Djokovic, assuming he gets past Mariano Navone in his own first-round match. That would put Wawrinka and Djokovic on the same court ten years after Wawrinka beat him in the 2016 US Open final, which is a large part of why this section of the draw is getting the attention it is.
