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 | LAA | Why |
|---|---|---|---|
| Team rating | 1518 | 1457 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | 0 | −4 | SEA: Bryan Woo: team allows 0.00 fewer runs than with its usual starter (≈10 weighted starts) · LAA: Jose Soriano: team allows 0.18 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SEA +47 Elo | SEA 56.7% | |
| Market-implied ratings | SEA 53.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SEA 54.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SEA 54.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
