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 | PIT | Why |
|---|---|---|---|
| Team rating | 1481 | 1479 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +3 | +17 | STL: Kyle Gibson: team allows 0.13 fewer runs than with its usual starter (≈10 weighted starts) · PIT: Mitch Keller: team allows 0.86 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | PIT +30 Elo | PIT 54.3% | |
| Market-implied ratings | STL 50.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | PIT 50.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PIT 53.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
