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 | STL | Why |
|---|---|---|---|
| Team rating | 1512 | 1497 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −4 | +1 | SD: Wandy Peralta: team allows 0.20 more runs than with its usual starter (≈1 weighted starts) · STL: Dustin May: team allows 0.05 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | STL +8 Elo | STL 51.2% | |
| Market-implied ratings | STL 52.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | STL 52.2% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | STL 57.5% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
