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 | DET | Why |
|---|---|---|---|
| Team rating | 1519 | 1528 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −8 | −22 | SEA: Logan Gilbert: team allows 0.39 more runs than with its usual starter (≈10 weighted starts) · DET: Jack Flaherty: team allows 1.08 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | DET +14 Elo | DET 52.0% | |
| Market-implied ratings | SEA 51.3% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SEA 50.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SEA 51.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
