PREDICTION RATIONALE โ€” Spain vs Saudi Arabia  (FIFA World Cup 2026, Group H, Matchday 3)
Venue: Neutral site (USA)

1. DATA. Last-10 internationals (Sofascore interception scraper).
   Spain: record WWWWDWDDWD, 2.50 GF / 0.40 GA,
   xG 2.48 / xGA 0.45.
   Saudi Arabia: record WLWLLLLWDD, 1.10 GF / 1.30 GA,
   xG 0.65 / xGA 1.59.
   Opponent-strength tiers (configs.MASTER_TIERS) applied per match.

2. RATINGS. Spain atk 1.59 def 0.54; Saudi Arabia atk 0.78 def 0.97.
   NEUTRAL VENUE: home boost / away penalty set to 1.0/1.0 (both teams
   travel to a host-nation site; no host advantage applies โ€” a key difference
   from the Korea/Canada/USA host-nation games). lambda Spain 1.86, Saudi Arabia 0.78
   after 85% model weight + shrink to 1.3 baseline.
   Injuries: {'Spain': ['No major absences reported'], 'Saudi Arabia': ['No major absences reported']}.
   Context: Group H MD3. Spain heavy favourites; Saudi a real AFC side. Expect the model to under-rate Spain (cold-on-elites bias). Neutral venue. MD3 rotation risk if group is decided.

3. MODEL. Bivariate Poisson (lambda3 0.12). 1X2 Spain 63.3% /
   draw 22.9% / Saudi Arabia 13.8%. Winner Spain; score 1-0; fair AH Spain -1.00.
   Over 2.5 48.5%; BTTS 46.7%.

4. EVENTS. Referee TBD: 4.2 Y + 0.13 R/match
   blended (weight 0.33) with WC base 2.9923 -> expected
   cards 3.43, P(over 3.5) 44.8%; P(any red)
   12.2%. Corners expected 9.4 (scale
   0.9997) -> P(over 8.5) 60.2%.

5. LIMITATIONS. 10-match samples; hand-set tiers/priors; Poisson corners; lineups
   probable not confirmed; card base rate calibrated on only 4 WC matches.
