How the number is built
Elo inputs in rating points (higher favors that team; 25–28 Elo is about a point of spread in football and basketball), then how the pieces combine.
| Factor | DET | HOU | Why |
|---|---|---|---|
| Team rating | 1491 | 1514 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −12 | +13 | DET: Kenta Maeda: team allows 0.60 more runs than with its usual starter (≈10 weighted starts) · HOU: Ronel Blanco: team allows 0.64 fewer runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | HOU +66 Elo | HOU 59.4% | |
| Market-implied ratings | HOU 59.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | HOU 59.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | HOU 59.9% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
