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 | HOU | COL | Why |
|---|---|---|---|
| Team rating | 1536 | 1389 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −9 | −11 | HOU: Brandon Walter: team allows 0.44 more runs than with its usual starter (≈4 weighted starts) · COL: Kyle Freeland: team allows 0.55 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | HOU +131 Elo | HOU 68.1% | |
| Market-implied ratings | HOU 61.0% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | HOU 62.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | HOU 63.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
