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 | SF | Why |
|---|---|---|---|
| Team rating | 1520 | 1487 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +11 | +7 | SD: Randy Vasquez: team allows 0.56 fewer runs than with its usual starter (≈10 weighted starts) · SF: Trevor McDonald: team allows 0.33 fewer runs than with its usual starter (≈2 weighted starts) |
| Elo ratings | SD +20 Elo | SD 52.9% | |
| Market-implied ratings | SD 51.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SD 51.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SD 54.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
