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 | MIA | HOU | Why |
|---|---|---|---|
| Team rating | 1495 | 1489 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +3 | +7 | MIA: Sandy Alcantara: team allows 0.15 fewer runs than with its usual starter (≈10 weighted starts) · HOU: Peter Lambert: team allows 0.37 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | HOU +16 Elo | HOU 52.3% | |
| Market-implied ratings | MIA 50.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | MIA 50.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | HOU 50.5% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
