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 | ARI | COL | Why |
|---|---|---|---|
| Team rating | 1506 | 1384 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +6 | −23 | ARI: Nabil Crismatt (no track record yet) · COL: Antonio Senzatela: team allows 1.17 more runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | ARI +134 Elo | ARI 68.4% | |
| Market-implied ratings | ARI 63.0% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | ARI 63.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | ARI 56.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
