The Setup
Iga Świątek, the 8th seed, and Liudmila Samsonova, the 19th seed, are set for a Wimbledon quarterfinal showdown. Świątek, the reigning French Open champion, has clawed her way to relevance on grass after a lackluster clay season, while Samsonova, a rising star, is making her first Grand Slam quarterfinal appearance. The stakes? Świątek’s quest for her first Wimbledon title and Samsonova’s bid to etch her name into tennis history.

- Matchup Context: Świątek has dropped only one set in Wimbledon 2025; Samsonova has yet to drop a set but faced weaker opposition.

Key Player Updates
- Świątek: No injuries reported. She’s vocal about her growing comfort on grass: “I feel like I am doing a great job, learning to play on grass… the process has some logic.”
- Samsonova: No major injuries, but her inexperience in high-pressure Grand Slam matches could be a liability.
The Sarcasm Meter
Let’s be real: Samsonova is the underdog, and her 31.25% implied probability is just 1.25% above the tennis underdog win rate of 30%. That’s like betting on a snowball’s chance in hell… but with slightly better odds. Meanwhile, Świątek’s 73.5% implied probability feels almost generous given her 4-0 head-to-head and superior stats.
Expected Value (EV) Calculation
1. Świątek’s Implied Probability: 1 / 1.36 ≈ 73.5%
- Adjusted for her 4-0 H2H and grass stats, her true probability is likely ~75-80%.
- EV: (0.75 * 0.36) - (0.25 * 1) = +8.8% per $1 bet.
- Samsonova’s Implied Probability: 1 / 3.2 ≈ 31.25%
- Her true probability aligns with the tennis underdog win rate (30%).
- EV: (0.3 * 2.2) - (0.7 * 1) = -0.4% per $1 bet.
The Verdict
While Samsonova’s “upset potential” is tempting, Świątek’s dominance on grass and the stark disparity in their stats make her the clear EV-positive play. The spread (-3.5 games) also favors Świątek, but the moneyline is the most straightforward bet.
Best Bet: Iga Świątek Moneyline (+1.36)
- Why: Her 75-80% true probability vs. 73.5% implied gives her a +8.8% edge. Even if she loses, the 4-0 H2H and grass stats make this a low-risk play.
- Pick Against the Spread: If you’re feeling spicy, take Świątek -3.5 games at +1.77. She’s likely to win by more than a set.
Final Thought
Samsonova’s journey to this point is inspiring, but Świątek is the machine here. Bet on the machine. Unless you’re a masochist, in which case, go with the snowball in hell. 🎾🔥
