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 | ATH | Why |
|---|---|---|---|

| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | 0 | −8 | KC: Kris Bubic: team allows 0.00 more runs than with its usual starter (≈9 weighted starts) · ATH: Aaron Civale: team allows 0.42 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | ATH +4 Elo | ATH 50.5% | |
| Market-implied ratings | KC 50.8% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | KC 50.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | ATH 50.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
