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 | 1432 | 1493 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −10 | +3 | ATH: Luis Severino: team allows 0.49 more runs than with its usual starter (≈10 weighted starts) · KC: Michael Wacha: team allows 0.16 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | KC +92 Elo | KC 63.0% | |
| Market-implied ratings | KC 60.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | KC 60.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | KC 59.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
