Edge Calculation
- Model P(Under 19.5): 54%
- Market No-Vig P(Under 19.5): 44%
- Edge: +10.0 pp raw → adjusted for uncertainty: ~3.7 pp
Factors Driving Total:
Favoring Under:
- High hold differential (+12.2%) - Alexandrova should dominate service games
- Sonmez’s low hold % (61.6%) - Vulnerable to multiple breaks per set
- Expert consensus: 2-0 - Multiple sources predict straight sets
- 68% straight sets probability - Fewer games in 2-set matches
- H2H precedent - 21 games on grass (6-3, 7-6) but hard court favors faster results
Favoring Over:
- Alexandrova’s poor 2026 form (1-2) - may struggle early
- Sonmez’s momentum (4-0 in qualifying)
- Tiebreak potential if Alexandrova goes cold (lost 2 TBs to Raducanu at AO 2025)

H2H Margin Reference
- Wimbledon 2025: Alexandrova won 6-3, 7-6(1) → margin of +4 games
- On grass (slower than hard) - expect similar or larger margin on hard
Handicap Factors:
Favoring Alexandrova covers (-4.5):
- Hold rate advantage creates consistent pressure
- Sonmez unlikely to hold serve against quality opponent
- Power differential (22 winners vs 13 at Wimbledon)
- Ranking gap (#11 vs #112) historically correlates with margin
Favoring Sonmez covers (+4.5):
- Alexandrova’s early season form concerns
- Sonmez playing well, full of confidence
- New coaching team (Jabeur/Jellali) may help
- H2H only showed +4 margin on grass

| Target Price |
2.00 or better (current 2.20) |
| Edge |
3.7 pp |
| Confidence |
MEDIUM |
| Stake |
1.0 units |
Rationale: The 12.2% hold rate differential strongly favors Alexandrova dominating. Sonmez’s 61.6% hold % means multiple breaks per set are likely. With 68% straight sets probability and expert consensus on 2-0, the under is the value side. The market has over-priced the over due to tiebreak fear, but Alexandrova dominated the only TB they played 7-1.
GAME SPREAD RECOMMENDATION

Alexandrova -4.5 |
| Target Price |
1.90 or better |
| Edge |
2.8 pp |
| Confidence |
LOW |
| Stake |
0.5 units |
Rationale: Model projects -4.8 game margin, making -4.5 the value side. However, confidence is low due to Alexandrova’s poor early-season form and Sonmez’s momentum. The H2H margin was exactly +4 on grass, which should be similar or better on hard. Take small position.
Pass Conditions:
- Pass on Totals if: Line moves to 20.5 or higher (edge disappears)
- Pass on Spread if: Line moves to -5.5 (model shows negative edge)
- Pass on Both if: Alexandrova shows injury/fitness concerns pre-match
10. Risk & Unknowns
Variance Drivers:
- Tiebreak volatility - Alexandrova’s TB record is mixed (1-2 third-set TBs), but dominated Sonmez 7-1
- Hold rate uncertainty - First hard court meeting; stats from mixed surfaces
- Form trajectory - Alexandrova trending down, Sonmez trending up
Data Limitations:
- No specific hard court hold % for Sonmez
- Sonmez tiebreak sample size too small for reliable modeling
- Average games/match data extrapolated from limited sources
- Spread odds not available at time of analysis
Correlation Considerations:
- Under 19.5 and Alexandrova -4.5 are positively correlated
- If playing both, reduce stakes slightly to manage exposure
- Combined max: 1.5 units total (vs 1.5 units individual)
