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 | DET | Why |
|---|---|---|---|
| Team rating | 1501 | 1508 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +7 | +16 | PIT: Jared Jones: team allows 0.37 fewer runs than with its usual starter (≈10 weighted starts) · DET: River Ryan: team allows 0.78 fewer runs than with its usual starter (≈4 weighted starts) |
| Elo ratings | DET +33 Elo | DET 54.8% | |
| Market-implied ratings | PIT 51.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | PIT 50.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | DET 52.5% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
