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 | COL | WSH | Why |
|---|---|---|---|
| Team rating | 1415 | 1466 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −4 | −9 | COL: Gabriel Hughes: team allows 0.19 more runs than with its usual starter (≈6 weighted starts) · WSH: Jake Irvin: team allows 0.43 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | WSH +65 Elo | WSH 59.2% | |
| Market-implied ratings | WSH 54.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | WSH 55.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | WSH 57.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
