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 | CHC | Why |
|---|---|---|---|
| Team rating | 1468 | 1520 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −12 | −26 | PIT: Paul Skenes: team allows 0.60 more runs than with its usual starter (≈1 weighted starts) · CHC: Kyle Hendricks: team allows 1.31 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | CHC +56 Elo | CHC 58.0% | |
| Market-implied ratings | CHC 54.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHC 54.7% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PIT 52.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
