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 | MIA | KC | Why |
|---|---|---|---|
| Team rating | 1499 | 1480 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +13 | +15 | MIA: Sandy Alcantara: team allows 0.64 fewer runs than with its usual starter (≈10 weighted starts) · KC: Michael Wacha: team allows 0.77 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | KC +2 Elo | KC 50.2% | |
| Market-implied ratings | MIA 51.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | MIA 50.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | KC 53.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
