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 | SEA | COL | Why |
|---|---|---|---|
| Team rating | 1517 | 1439 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −19 | +8 | SEA: Emerson Hancock: team allows 0.94 more runs than with its usual starter (≈5 weighted starts) · COL: Peter Lambert: team allows 0.38 fewer runs than with its usual starter (≈7 weighted starts) |
| Elo ratings | SEA +34 Elo | SEA 54.9% | |
| Market-implied ratings | SEA 55.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SEA 55.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SEA 52.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
