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 | LAA | SEA | Why |
|---|---|---|---|
| Team rating | 1440 | 1525 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +9 | −18 | LAA: Tyler Anderson: team allows 0.44 fewer runs than with its usual starter (≈10 weighted starts) · SEA: Emerson Hancock: team allows 0.89 more runs than with its usual starter (≈8 weighted starts) |
| Elo ratings | SEA +76 Elo | SEA 60.8% | |
| Market-implied ratings | SEA 54.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SEA 55.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SEA 56.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
