NARRATIVE
Let-down: none live. Zverev TITLE French Open 34d ago (clay) — too old to matter.
Venue: both 6-0 this event. Sinner peaking (DOM vs Elite); Zverev surviving on tiebreaks.
MARKET-BY-MARKET
ML: Models say Zverev value (ML model 49.1%!) but qualitative read kills it —
Sinner just straight-setted Djokovic, crushed Zverev 6-1 6-2 last meeting,
Zverev grinding through TBs all fortnight. ML 49.1% not credible. PASS.
Handicap: Sinner -4.5 @ 1.77 — sim covers 56.2% vs 56.5% implied. Zero edge, and
Zverev's TB-heavy grass serve profile makes -4.5 fragile (7-6 sets kill it). PASS.
TOTAL: Market line 38.5 — Under 1.98 (50.5% implied), Over 1.95.
Sim: under 37.5 = 57% → under 38.5 ≈ 60% (extra game of cushion vs sim line).
Qualitative correction STRENGTHENS under: sim generated the match at Sinner 67.5%,
market says 80% — the truer, more lopsided match is shorter than the sim's.
Straight-set Sinner win (likeliest single path) lands 30-37 games. Edge ~+9.5%.
VERDICT: BET Under 38.5 games @ 1.98 (Betfair) — 1.5u
Win prob 60% vs 50.5% implied. Margin thesis without a winner thesis: agree with
market on Sinner, disagree with a 50/50 total in a matchup one side is dominating.
Risks: Zverev serve + grass → TB sets inflate count; any 5-setter (and most
4-setters) goes over; three-TB straight sets (39) busts it.
Predicted winner: J. Sinner.
