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 |
|---|---|---|---|
| Team rating | 1428 | 1473 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +2 | +5 | COL: Cal Quantrill: team allows 0.12 fewer runs than with its usual starter (≈9 weighted starts) · PIT: Martin Perez: team allows 0.23 fewer runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | PIT +65 Elo | PIT 59.2% | |
| Market-implied ratings | PIT 65.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | PIT 64.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PIT 63.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
