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 | CHW | Why |
|---|---|---|---|
| Team rating | 1479 | 1426 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +13 | −19 | WSH: Trevor Williams: team allows 0.63 fewer runs than with its usual starter (≈10 weighted starts) · CHW: Chris Flexen: team allows 0.97 more runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | WSH +66 Elo | WSH 59.4% | |
| Market-implied ratings | WSH 52.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | WSH 53.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | WSH 52.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
