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 | SD | COL | Why |
|---|---|---|---|
| Team rating | 1532 | 1405 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +10 | −4 | SD: Randy Vasquez: team allows 0.51 fewer runs than with its usual starter (≈10 weighted starts) · COL: Jimmy Herget: team allows 0.20 more runs than with its usual starter (≈2 weighted starts) |
| Elo ratings | SD +123 Elo | SD 67.0% | |
| Market-implied ratings | SD 57.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SD 59.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SD 57.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
