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 | SF | Why |
|---|---|---|---|
| Team rating | 1470 | 1475 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −6 | +2 | WSH: Patrick Corbin: team allows 0.30 more runs than with its usual starter (≈10 weighted starts) · SF: Jordan Hicks: team allows 0.09 fewer runs than with its usual starter (≈2 weighted starts) |
| Elo ratings | SF +31 Elo | SF 54.5% | |
| Market-implied ratings | SF 63.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SF 61.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SF 63.9% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
