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 | PIT | Why |
|---|---|---|---|

| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +5 | +2 | COL: Jose Quintana: team allows 0.23 fewer runs than with its usual starter (≈10 weighted starts) · PIT: Mitch Keller: team allows 0.09 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | PIT +106 Elo | PIT 64.9% | |
| Market-implied ratings | PIT 62.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | PIT 62.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PIT 62.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
