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 | SD | Why |
|---|---|---|---|
| Team rating | 1523 | 1538 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +14 | −7 | SEA: Bryan Woo: team allows 0.70 fewer runs than with its usual starter (≈10 weighted starts) · SD: Michael King: team allows 0.34 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SD +13 Elo | SD 51.8% | |
| Market-implied ratings | SD 56.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SD 56.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SD 57.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
