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 | KC | CHW | Why |
|---|---|---|---|
| Team rating | 1503 | 1436 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +2 | +8 | KC: Michael Lorenzen: team allows 0.09 fewer runs than with its usual starter (≈10 weighted starts) · CHW: Martin Perez: team allows 0.38 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | KC +43 Elo | KC 56.1% | |
| Market-implied ratings | KC 53.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | KC 54.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | KC 51.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
