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 | CHW | SF | Why |
|---|---|---|---|
| Team rating | 1383 | 1497 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −14 | −14 | CHW: Davis Martin: team allows 0.68 more runs than with its usual starter (≈3 weighted starts) · SF: Robbie Ray: team allows 0.69 more runs than with its usual starter (≈5 weighted starts) |
| Elo ratings | SF +132 Elo | SF 68.1% | |
| Market-implied ratings | SF 70.8% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SF 70.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SF 69.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
