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 | MIA | SEA | Why |
|---|---|---|---|
| Team rating | 1464 | 1520 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −10 | −1 | MIA: Connor Gillispie: team allows 0.48 more runs than with its usual starter (≈4 weighted starts) · SEA: Luis Castillo: team allows 0.06 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SEA +82 Elo | SEA 61.6% | |
| Market-implied ratings | SEA 65.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SEA 65.2% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SEA 67.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
