Prediction: Jan-Lennard Struff VS Felix Auger-Aliassime 2025-07-02

Wimbledon 2025: Felix Auger-Aliassime vs. Jan-Lennard Struff – A Tale of Two Grass Courts

The Setup
Félix Auger-Aliassime, the 25th seed and a man who’s turned grass into his personal putting green (Montpellier title, semifinals in Stuttgart and Mallorca), faces Jan-Lennard Struff, the last German hope in SW19. Struff, a gritty veteran with a 3-2 career edge over Auger-Aliassime, is clinging to relevance after a lackluster 2025 season (Marseille quarterfinals being his lone highlight). The match, postponed from a dramatic tiebreak collapse, now offers Auger-Aliassime a fresh chance to flex his grass-court muscles—against a man who’s never beaten him on this surface.

The Numbers Game
- Odds Breakdown:
- Auger-Aliassime: Decimal odds of 1.36–1.37 (implied probability: ~73–74%).
- Struff: Decimal odds of 3.05–3.20 (implied probability: ~31–33%).
- Underdog Win Rate in Tennis: 30%. Struff’s implied 32% suggests the market slightly overvalues him.

Head-to-Head: Auger-Aliassime leads 3-2, but this is their first grass-court clash. Struff’s confidence? Thin as Wimbledon’s middle Sunday crowd.

Form & Fitness:
- Auger-Aliassime: Fresh off a 5-set marathon vs. Duckworth (3h45m), but his grass-court form is chef’s kiss.
- Struff: No major injuries, but his 2025 is a leaky sieve (19-18 record).

The Calculus of Chaos
Using the Odds Expected Value (EV) formula:
- Auger-Aliassime’s EV:
- Implied probability: ~73.5% (1/1.36).
- Actual probability? Let’s split the difference between his implied 73.5% and the underdog rate (30%). If Struff’s true chance is ~30%, Auger-Aliassime’s edge is ~70%.
- EV = (0.70 * 1.36) - (0.30 * 1) = 0.952 - 0.30 = +0.652. Solid positive EV.

Struff’s EV:
- Implied probability: ~32%.
- Actual probability? Closer to the 30% underdog rate.
- EV = (0.30 * 3.1) - (0.70 * 1) = 0.93 - 0.70 = +0.23. Marginally positive, but not worth the risk.

The Verdict
Best Bet: Félix Auger-Aliassime (-5.5 sets, 1.36–1.37)
Why? Auger-Aliassime’s grass-court mastery, Struff’s underwhelming 2025, and the math all scream “back the Canadian.” The -5.5 spread? A tasty spread for a player who’s outperformed his implied probability in recent grass-court clashes.

Witty Warning:
Struff might as well pack his bags for Berlin. Auger-Aliassime isn’t just a favorite—he’s a grass-court gremlin in a tennis suit. Unless Struff brings a time machine to undo that 2021 Marseille quarterfinal, this is a match where the underdog’s best hope is to serve and pray.

Final Score Prediction: Auger-Aliassime in straight sets (6-3, 6-4, 6-3). Struff’s resilience? Adorable. His chances? Slim, none, and paper-thin.
