═══ C. Hewitt vs D. Lajovic — Washington (hard) ═══

MODELS vs MARKET
  ELO: 33.5% A | ML: 47.5% A | Combined: 34.8% A
  Book: 6.30 / 1.08 (implied A 14.6%) — stale/outlier quote
  Betfair (executable): 4.50 / 1.27 → implied A 22.2% / B 78.7%
  Numerical gap exists (models 33-47% A vs exchange 22%) — but see ELO sanity below.

ELO vs RANKING SANITY — DECISIVE
  Hewitt: 17 years old, ATP rank 653. Entire 90d sample is Boys Wimbledon (junior)
  and M15/M25 futures. Opponent ELOs 1235-1744, mostly Weak/Avg bracket. This is a
  farmed rating: an ELO/ML read of 33-47% vs a rank-132 tour veteran is not credible.
  High-ELO/modest-rank flag → discount the model edge entirely.
  Lajovic: rank 132, age 36 — ELO and rank roughly consistent; credible.

RECENT FORM (last 5 shown; all matches used)
  Hewitt (17): 5-0 at Boys Wimbledon (junior draw, opp ELO 1500-1744), before that
  scattered futures results incl. losses to sub-1500 opponents (Vandecasteele,
  McDonald 1487, Wehnelt 1354). No tour-level match in sample. Grass→hard TRANSITION.
  Lajovic (36): L to van Assche (Umag, clay, 3 sets), L Fritz (Wimbledon R64),
  mixed challenger/tour results — mediocre but tour-level opposition throughout
  (Tabilo 1853, Altmaier 1740, Rocha 1708). Clay→hard TRANSITION.

FATIGUE
  Hewitt: 0 matches / 14d, well rested. Lajovic: 1 match (172 min) on 07-13, 12 days
  rest — effectively fresh. Roughly equal; no fatigue angle. (Ages 17 / 36 noted;
  no penalty applied to either — both rested.)

NARRATIVE
  Let-down: none live (Lajovic's June 25 "Final" loss is 30d old, outside window).
  Venue: no Washington history in sample for either. Title recency: none.
  Both players in surface transition → wider margin uncertainty; no alt markets
  priced anyway (handicap/totals null).

GATES
  G1 edge-origin: FAIL — the raw model-market gap rests on an ELO/ML rating farmed
     at junior + M25 events; after the ELO-sanity discount there is no credible
     numerical edge on Hewitt, and no edge exists on Lajovic (need ~79.6% at 1.27
     commission-adj; discounted read gives him ~65-72%).
  G2 consensus:   FAIL — exchange prices Lajovic 79%; the only pro-Hewitt evidence
     is the farmed ELO/ML split, a lone-model signal with zero tour-level results
     to validate it.
  G3 fatal-risk:  FAIL — backing a rank-653 17-year-old at 4.5 vs a rank-132
     veteran on the strength of junior-event ratings is itself the negating risk.

VERDICT: PASS. The 20% "value edge" on Hewitt is a model artifact from a junior-
farmed rating; the exchange (1.27/4.50) is the credible read and neither side
clears the 5% bar against it. No alt markets priced. No bet.
