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 | PIT | PHI | Why |
|---|---|---|---|
| Team rating | 1457 | 1532 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −1 | +11 | PIT: Carmen Mlodzinski: team allows 0.05 more runs than with its usual starter (≈7 weighted starts) · PHI: Zack Wheeler: team allows 0.53 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | PHI +105 Elo | PHI 64.6% | |
| Market-implied ratings | PHI 71.0% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | PHI 70.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PHI 73.8% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
