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 | BAL | KC | Why |
|---|---|---|---|
| Team rating | 1487 | 1488 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | 0 | −1 | BAL: Shane Baz: team allows 0.02 more runs than with its usual starter (≈10 weighted starts) · KC: Kris Bubic: team allows 0.03 more runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | KC +19 Elo | KC 52.7% | |
| Market-implied ratings | KC 54.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | KC 54.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | KC 54.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
