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 | STL | CHC | Why |
|---|---|---|---|
| Team rating | 1480 | 1500 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | 0 | +14 | STL: Andre Pallante: team allows 0.02 fewer runs than with its usual starter (≈3 weighted starts) · CHC: Shota Imanaga: team allows 0.70 fewer runs than with its usual starter (≈7 weighted starts) |
| Elo ratings | CHC +52 Elo | CHC 57.4% | |
| Market-implied ratings | CHC 60.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHC 60.2% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHC 62.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
