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 | HOU | Why |
|---|---|---|---|
| Team rating | 1386 | 1512 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +8 | +6 | COL: Chase Dollander: team allows 0.41 fewer runs than with its usual starter (≈8 weighted starts) · HOU: Framber Valdez: team allows 0.29 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | HOU +141 Elo | HOU 69.3% | |
| Market-implied ratings | HOU 72.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | HOU 71.7% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | HOU 71.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
