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 | 1493 | 1391 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −6 | 0 | KC: Michael Wacha: team allows 0.31 more runs than with its usual starter (≈10 weighted starts) · CHW: Jonathan Cannon: team allows 0.02 fewer runs than with its usual starter (≈7 weighted starts) |
| Elo ratings | KC +78 Elo | KC 61.0% | |
| Market-implied ratings | KC 62.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | KC 62.2% | 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 | |
