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 | 1517 | 1480 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −2 | +10 | SD: Matt Waldron: team allows 0.11 more runs than with its usual starter (≈5 weighted starts) · SF: Logan Webb: team allows 0.52 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SD +7 Elo | SD 51.0% | |
| Market-implied ratings | SF 52.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SF 52.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SF 59.9% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
