Taylor Fritz enters Saturday’s US Open third-round matchup with Francisco Cerúndolo in a position bettor like to see: the favorite has been winning efficiently, while the opponent has already been forced through a physically demanding match.
But this is not simply a case of backing the higher-ranked player.
The betting opportunity comes from determining whether Fritz’s serve and recent efficiency can create enough separation to justify laying the games.

Why This Match Matters to Bettors
Fritz has not merely advanced through the first two rounds.
He has done so while barely allowing opponents to make the matches competitive.
He opened the tournament by defeating Darwin Blanch 6-3, 6-2, 6-4 before producing an even more dominant result against Mattia Bellucci, winning 6-0, 6-1, 6-1.
That creates an important contrast with Cerúndolo.
The Argentine also won his first two matches, but his second-round victory over Jan-Lennard Struff went five sets.
This isn’t enough by itself to predict fatigue.
It does, however, change the physical context entering a best-of-five match.
Key Betting Numbers
Current market listings have Fritz around 1.14, equivalent to approximately -614 American odds, while Cerúndolo is around 5.50, or approximately +450.
The game handicap is currently appearing around Fritz -6.5, with a total around 35.5 games in one current market snapshot. Prices vary between sportsbooks, so bettors should compare before placing a wager.
That distinction is important.
The moneyline asks whether Fritz wins.
The handicap asks whether he wins by enough.
At a price this expensive on the moneyline, the second question is considerably more interesting.
The Serve Is Fritz’s Biggest Weapon
Fritz’s second-round numbers explain why the market has made him such a heavy favorite.
Against Bellucci, he hit 11 aces, committed only one double fault, won 86% of first-serve points and 62% behind his second serve.
Most importantly, he did not lose serve once.
He also converted eight of 15 break opportunities.
That is the type of performance that creates separation against a dangerous opponent.
Fritz doesn’t have to dominate every baseline exchange.
If he continues protecting his service games, Cerúndolo will need to produce consistently on return just to stay within striking distance.
Cerúndolo Has a Different Kind of Advantage
There is a reason not to dismiss the underdog.
Cerúndolo is a high-quality competitor and has already demonstrated that he can survive difficult situations at this tournament.
His five-set victory over Struff lasted roughly 234 minutes. Current match data also shows that Cerúndolo produced 19 aces in that match, although he committed 13 double faults.
That combination tells us something important.
Cerúndolo has enough power to hurt Fritz.
But there is volatility in his service performance.
Against an opponent as dangerous as Fritz, giving away free points could make the difference between a competitive set and a runaway set.
Hidden Betting Edge: The Workload Gap
The obvious story is Fritz’s ranking.
The less obvious story is the amount of tennis each player has already played.
Fritz’s Bellucci match was effectively over after three sets and just 27 games.
Cerúndolo had to navigate five sets against Struff.
That matters more in men’s Grand Slam tennis because the third round is still best-of-five.
If the match reaches the fourth or fifth set, the physical workload from the previous round becomes more relevant.
If the match stays short, Fritz’s serving advantage becomes even more valuable.
Either scenario provides a plausible route for the favorite to create separation.
What Could Go Wrong?
Cerúndolo could make this bet uncomfortable by serving efficiently and forcing Fritz into longer rallies.
A couple of close sets could also create a problem.
Fritz could win 7-6, 6-4, 6-4 and still fail to cover -6.5 depending on the exact game count.
The head-to-head is another reason for caution. Fritz and Cerúndolo are 1-1 overall, with Fritz winning their most recent meeting in Madrid in 2024. They have never met on hard court.
So there is no previous hard-court matchup to rely on as a direct comparison.
Live Betting Opportunity
Watch Cerúndolo’s first two return games.
If Fritz is consistently getting ahead in service games and Cerúndolo is struggling to generate pressure on second serves, a live Fritz handicap may offer value.
But if Cerúndolo is holding comfortably and forcing Fritz into extended rallies, don’t chase the favorite simply because the pre-match model favored him.
Best Bet
Taylor Fritz -6.5 Games
Current Odds: Around -120 where available
Confidence: ★★★★☆
Risk Level: Moderate
Fritz has the cleaner tournament profile entering this match. He is serving efficiently, protecting his service games and finishing points without having to grind through long matches.
Cerúndolo has the quality to compete, but the combination of Fritz’s serve and the Argentine’s heavier workload creates a favorable setup for the favorite to win by margin.
Why Bettors Should Watch This
This matchup illustrates one of the most important concepts in tennis betting:
A heavy favorite doesn’t automatically equal a bad bet.
Sometimes the moneyline becomes unusable because of the price while the handicap remains playable.
That is the situation to monitor here.
