Split the Difference:
- Mertens’ implied (44.4%) vs. historical underdog rate (30%) → 14.4% edge for the underdog.
- Svitolina’s implied (61.5%) vs. favorite win rate (70% typical) → -8.5% edge for the favorite.

Expected Value (EV) Calculation:
- Svitolina:
- EV = (0.615 * 0.615) - (0.385 * 0.385) ≈ +13.8%.
- Wait, no. Let’s do it properly:
- For a $100 bet on Svitolina (-160):
- Profit if she wins: $62.50.
- EV = (0.615 * 62.50) - (0.385 * 100) = $38.44 - $38.50 ≈ -$0.06 (slightly negative).
- Mertens:
- For a $100 bet on Mertens (+125):
- Profit if she wins: $125.
- EV = (0.444 * 125) - (0.556 * 100) = $55.50 - $55.60 ≈ -$0.10 (also slightly negative).

Verdict: Both bets are marginally negative, but Svitolina’s EV is closer to zero.

### The Play: Best Bet
Pick: Elina Svitolina (-160)
- Why?
1. Grass-Court Expertise: Svitolina’s 2022 Wimbledon semifinal and Mertens’ 2023 quarterfinal suggest both are grass specialists, but Svitolina’s recent 77-minute win shows she’s in peak form.
2. Head-to-Head Edge: Svitolina’s 2-1 record includes a 2022 Rome Masters win over Mertens.
3. Momentum: Svitolina’s aggressive, serve-and-volley style suits Wimbledon’s grass courts better than Mertens’ baseline grind.

Contrarian Note: Mertens’ 30% underdog win rate in tennis gives her a fighting chance, but her 2025 inconsistency makes her a risky +125 bet.

### Spread & Total Bets
- Spread (-2.5 games): Svitolina -2.5 at ~1.91.
- Take the favorite: Svitolina’s recent efficiency (77-minute win) suggests she’ll dominate games.
- Total (22.5 games): Under at ~1.83.
- Play the Under: Svitolina’s serve and Mertens’ defensive style could lead to a quick match.

---

### Final Verdict
Svitolina is the safer, marginally positive EV bet despite the slight negative EV. Mertens’ underdog allure is tempting, but history and form favor the Ukrainian. As Svitolina said after her last win, “It was a great day.” Let’s assume she means it—and that her next day will be even greater.
