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 | BAL | PIT | Why |
|---|---|---|---|
| Team rating | 1486 | 1487 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −1 | −6 | BAL: Shane Baz: team allows 0.04 more runs than with its usual starter (≈10 weighted starts) · PIT: Carmen Mlodzinski: team allows 0.30 more runs than with its usual starter (≈8 weighted starts) |
| Elo ratings | PIT +13 Elo | PIT 51.9% | |
| Market-implied ratings | BAL 50.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | BAL 50.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PIT 50.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
