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 | TB | CHC | Why |
|---|---|---|---|
| Team rating | 1505 | 1535 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +11 | −16 | TB: Drew Rasmussen: team allows 0.54 fewer runs than with its usual starter (≈10 weighted starts) · CHC: Colin Rea: team allows 0.82 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | CHC +21 Elo | CHC 53.1% | |
| Market-implied ratings | CHC 50.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHC 50.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHC 50.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
