MATCH: M. Damm (rank 115, age 22) vs A. Shelbayh (rank 279, age 22)
Washington — Final — hard

MODELS vs MARKET
  Book: Damm 1.27 (73.7%) / Shelbayh 3.55 (28.2%)
  Betfair ML: 1.03 / 1.01 — invalid/illiquid quotes (sum ~196% implied), UNUSABLE. No executable exchange price -> book-priced segment.
  ELO: Damm 65.8% | ML: Damm 59.1% | Blend: Damm 64.8%
  Value flag: B (Shelbayh) +8.8% vs book on the blend of components; blended model edge for B = 35.2% - 28.2% = 7.0%.
  ELO/ranking sanity: Damm ELO-favourite and ranked 115 vs 279 — ELO and rank agree, credible.

RECENT FORM (most recent 5)
  Damm: W Coppejans (1578, Avg) 6-2 6-0 DOM — Washington SF; L Rinderknech (1630) Wimbledon R64 (competitive, TB set); W Trungelliti (1448) Wimbledon R128 GRIND (multiple TBs); exhibition vs Khachanov; L Brooksby (1653) London 3 sets.
  Season shape: London title (beat Svajda 1824 in the final), pushed De Minaur to two tight sets — plays at/above his 115 rank vs Strong opposition.
  Shelbayh: W B. Harris (1568, Avg) 6-4 7-6 GRIND — Washington SF; L M. Zheng (1770) 6-4 6-1 blowout 6d ago at Bloomfield Hills; L Dimitrov Mallorca; mixed challenger results with repeated early exits (Bratislava, Heilbronn, Kosice 1/16 losses).

FATIGUE (both age 22)
  Damm: 1 match/14d, 63 min, last 07-25 — fresh (long layoff since Wimbledon, light schedule).
  Shelbayh: 2 matches/14d, 179 min, last 07-25. Raw court-time gap 116 min > 60 -> disadvantaged, but Shelbayh is 22 (fast recovery) -> softened to slight edge Damm. Not material either way — 2 matches in 14d is a light load.

NARRATIVE
  Let-down: Damm's most recent Final = London 06-14 (won, 42d ago) -> None. Shelbayh's = Mallorca 06-21 (35d ago) -> None.
  Venue: no prior Washington history in window for either.
  Title recency: Damm — TITLE: London 42d ago (grass). Shelbayh — TITLE: Heilbronn 55d ago (clay, Challenger).
  Surface transition: both have been on hard for their last matches — none.

GATES
  G1 edge-origin: FAIL — blended model edge for Shelbayh is 7.0% vs the book quote; no executable exchange price (betfair_ml 1.03/1.01 is junk), so the book-priced bar is 8%. Raw numeric edge is below the bar before any narrative input.
  G2 consensus:   FAIL — market is firmly on Damm and live form agrees (6-2 6-0 DOM semi vs Shelbayh's grind + a 6-4 6-1 blowout loss 6 days ago). Only the ML component (59.1%) disagrees materially; a lone model split with zero independent hard evidence for the dog does not pass.
  G3 fatal-risk:  FAIL — the dog thesis requires Shelbayh to hang with a player who just posted a double-break DOM win and owns the class markers (London title over Svajda 1824, tight sets vs De Minaur); Shelbayh's own recent blowout loss to a 1770 directly negates it.

VERDICT: PASS. The value flag on Shelbayh is a thin, book-priced 7% that dies at the 8% no-exchange bar, and every qualitative read (class, live form, freshness) points the other way. No alt markets priced. Damm to win the title.
