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 | PHI | MIA | Why |
|---|---|---|---|

| Starting pitchers | −9 | +9 | PHI: Aaron Nola: team allows 0.44 more runs than with its usual starter (≈10 weighted starts) · MIA: Janson Junk: team allows 0.47 fewer runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | MIA +6 Elo | MIA 50.9% | |
| Market-implied ratings | MIA 50.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | MIA 50.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | MIA 51.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
