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 | CHW | KC | Why |
|---|---|---|---|
| Team rating | 1430 | 1501 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | 0 | +10 | CHW: Aaron Civale: team allows 0.01 more runs than with its usual starter (≈10 weighted starts) · KC: Noah Cameron: team allows 0.48 fewer runs than with its usual starter (≈8 weighted starts) |
| Elo ratings | KC +99 Elo | KC 63.9% | |
| Market-implied ratings | KC 60.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | KC 61.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | KC 61.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
