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 | SF | MIA | Why |
|---|---|---|---|
| Team rating | 1480 | 1475 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +8 | −7 | SF: Jordan Hicks: team allows 0.38 fewer runs than with its usual starter (≈3 weighted starts) · MIA: Ryan Weathers: team allows 0.36 more runs than with its usual starter (≈8 weighted starts) |
| Elo ratings | SF +2 Elo | SF 50.3% | |
| Market-implied ratings | SF 55.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SF 54.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | SF 54.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
