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 | PIT | COL | Why |
|---|---|---|---|
| Team rating | 1491 | 1407 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −8 | −26 | PIT: Bubba Chandler: team allows 0.39 more runs than with its usual starter (≈8 weighted starts) · COL: Kyle Freeland: team allows 1.29 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | PIT +84 Elo | PIT 61.9% | |
| Market-implied ratings | PIT 55.3% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | PIT 56.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PIT 56.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
