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 | SD | PIT | Why |
|---|---|---|---|
| Team rating | 1523 | 1487 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +9 | +1 | SD: Nick Pivetta: team allows 0.43 fewer runs than with its usual starter (≈10 weighted starts) · PIT: Paul Skenes: team allows 0.06 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SD +25 Elo | SD 53.6% | |
| Market-implied ratings | PIT 55.8% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | PIT 54.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | PIT 58.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
