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 | PIT | STL | Why |
|---|---|---|---|
| Team rating | 1473 | 1487 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +8 | +3 | PIT: Luis Ortiz: team allows 0.41 fewer runs than with its usual starter (≈9 weighted starts) · STL: Erick Fedde: team allows 0.13 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | STL +27 Elo | STL 53.9% | |
| Market-implied ratings | STL 57.0% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | STL 56.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | STL 56.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
