Factors Driving Total
- Hold Rate Impact: Kostyuk (~75%) vs Jacquemot (~60%) creates asymmetric scenario. Jacquemot struggles to hold, while Kostyuk breaks frequently. This leads to shorter games, not extended rallies to TB.
- Tiebreak Probability: LOW (~12%). The hold/break differential suggests Kostyuk will break early and avoid tiebreaks. Jacquemot’s 0/3 BP conversion vs Frech and being broken 5x vs Tomljanovic indicates she won’t pressure Kostyuk’s serve.
- Straight Sets Risk: HIGH (85%). Expert consensus unanimous on Kostyuk 2-0. Jacquemot’s recent matches averaged just 10 total games.

Rationale: Kostyuk’s dominant serve (75% hold) combined with Jacquemot’s poor hold rate (~60%) and terrible 2026 form (averaging 4 games won) points to a blowout. The 85% straight sets probability and low tiebreak likelihood (12%) suggest a 6-3, 6-3 or 6-2, 6-4 scoreline (18 games). Under 20.5 has clear value.

| Stake |
1.0 units |
Rationale: Expected margin of -5.8 games gives comfortable cushion above -4.5 line. Jacquemot’s 4-game average in 2026 losses and Kostyuk’s form (12.4 games won avg at Brisbane) support a 5-6 game margin. If Kostyuk wins 6-2, 6-3 (typical dominant 2-0), margin is -7 games.
Pass Conditions
- Pass on totals if line moves to Under 18.5 or lower
- Pass on spread if line moves to Kostyuk -6.5 or higher
- Pass if significant injury news emerges for either player
Risk & Unknowns
Variance Drivers
- Grand Slam Stage Nerves: Jacquemot may compete better on big stage than warmup events
- Kostyuk Comedown: After Brisbane final loss, motivation/energy questions (mitigated by 6 days rest)
- Tiebreak Volatility: If match goes tighter than expected, even one TB adds 13 games to a set
Data Limitations
- Jacquemot exact hold % not available; estimated from poor recent form
- No H2H data for validation
- Market totals/spread lines estimated (not confirmed from bookmakers)
- Tiebreak sample for Jacquemot insufficient
Correlation Notes
- Totals Under and Kostyuk spread correlated (both benefit from dominant performance)
- Consider reducing combined exposure if betting both: max 1.5 units total
