- 06-22 Wimbledon QF W vs Sanchez Izquierdo (Avg 1500)
Solid level vs Strong/Avg opposition; only loss to an Elite. All recent matches on GRASS -> TRANSITION to hard.

Entire sample on CLAY vs Weak opposition (ELO 1031-1627), losing to sub-1450 players. TRANSITION to hard for him too.

FATIGUE
Both players 0 matches in 14d, well rested. Roughly equal — no fatigue angle (Kwon 28, Rubio 27, age-neutral).

NARRATIVE
- Let-down: none in window (Kwon's last Final win 30d ago; Rubio lost Troyes Final 26d ago — outside window).
- Venue: no Los Cabos history in sample for either.
- Surface transition: BOTH grass/clay -> hard; rust on both sides, no directional edge; widens margin uncertainty but no alt markets are priced anyway.

GATES
  G1 edge-origin: FAIL — best numeric edge is Kwon +2.1% vs book (needs 8% book-priced; even standard bar is 5%)
  G2 consensus:   PASS — models and market agree on Kwon; no contrarian claim made
  G3 fatal-risk:  PASS — no thesis staked, nothing to negate

VERDICT: PASS. Full model-market consensus on a heavy favorite at 1.07 with no exchange liquidity and no alt markets. Backing Kwon offers no payable edge; backing the dog contradicts every model and his own form (losing to 1180-1450 ELO players on clay). No bet.
