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 | SF | WSH | Why |
|---|---|---|---|
| Team rating | 1494 | 1452 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −3 | −19 | SF: Adrian Houser: team allows 0.17 more runs than with its usual starter (≈10 weighted starts) · WSH: Cade Cavalli: team allows 0.93 more runs than with its usual starter (≈8 weighted starts) |
| Elo ratings | SF +39 Elo | SF 55.6% | |
| Market-implied ratings | SF 53.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SF 53.5% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SF 51.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
