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 | ATH | Why |
|---|---|---|---|
| Team rating | 1486 | 1480 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −8 | +10 | PIT: Mitch Keller: team allows 0.41 more runs than with its usual starter (≈10 weighted starts) · ATH: Jack Perkins: team allows 0.48 fewer runs than with its usual starter (≈5 weighted starts) |
| Elo ratings | ATH +29 Elo | ATH 54.2% | |
| Market-implied ratings | ATH 55.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | ATH 55.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | ATH 56.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
