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 | ATH | KC | Why |
|---|---|---|---|
| Team rating | 1437 | 1488 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +4 | −11 | ATH: Jeffrey Springs: team allows 0.22 fewer runs than with its usual starter (≈9 weighted starts) · KC: Noah Cameron: team allows 0.54 more runs than with its usual starter (≈5 weighted starts) |
| Elo ratings | KC +54 Elo | KC 57.7% | |
| Market-implied ratings | KC 58.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | KC 58.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | KC 57.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
