Fritz’s -160 price translates to an implied probability of 61.5%, which aligns closely with projection models giving him a 57% chance to win. That’s not a massive edge for the books, suggesting there’s value on the favorite here. Especially when you consider Fritz’s dominant form in Stuttgart.

Fritz vs Auger-Aliassime Picks and Predictions

• Fritz Moneyline (-160 at MGM)
• Parlay: Fritz ML + Over 24.5 Games (+105 at Bet365)

Fritz has been serving absolute bombs through his first two matches in Stuttgart. The world No. 7 has blasted 24 aces without facing a single break point. Read that again. Not one break point against him in four sets of tennis on grass.

His dominance goes beyond just the serve. Fritz crushed Marton Fucsovics 6-3, 6-4 in the quarterfinals, winning 92% of his first serve points. Against Quentin Halys in the previous round, he was nearly as efficient. The American looks locked in after a disappointing clay-court season.

Meanwhile, Auger-Aliassime’s path has been less convincing. Sure, he hasn’t dropped a set either, but he’s been broken twice and faced six break points total. His wins came against Giovanni Mpetshi Perricard and Justin Engel. Not exactly murderer’s row compared to Fritz’s competition.

The Canadian started 2025 on fire, winning titles in Adelaide and Montpellier. But since March? It’s been rough. First-round exits in Monte Carlo, Munich, Madrid, and the French Open tell the story of a player searching for answers. This grass-court run is encouraging, but is it sustainable against elite competition?

Fritz vs Auger-Aliassime H2H Results

Fritz holds a 2-1 edge in their rivalry, though Auger-Aliassime took their most recent meeting at the United Cup. But here’s the kicker. They’ve never played on grass. All three matches came on hard courts in team competitions where the dynamics are different.

What really stands out is Fritz’s grass court pedigree. Last year, he went 10-2 on the surface, winning Eastbourne and reaching the Wimbledon quarterfinals. Auger-Aliassime? He lost in the first round of both Halle and Wimbledon. That’s a massive experience gap on this surface.

The oddsmakers have it right making Fritz the favorite. His serve has been untouchable, his confidence is soaring, and he’s playing at home in Germany where he’s always comfortable. While both guys can serve big, Fritz has been far more efficient in Stuttgart. Add in the parlay with over 24.5 games for extra value, as these two big servers could easily push each other to three sets.

Fritz’s form suggests he’s ready to make a deep run on grass this summer. Converting those 86% of first serve points while saving every break point he’s faced? That’s championship-level tennis. Auger-Aliassime will need to summon his best to have any chance, but Fritz’s current level might just be too high.
