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 | WSH | SD | Why |
|---|---|---|---|

| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +3 | −6 | WSH: Riley Cornelio (no track record yet) · SD: Casey Mize: team allows 0.31 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SD +62 Elo | SD 58.9% | |
| Market-implied ratings | SD 61.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SD 61.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SD 63.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
