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 | BOS | ATH | Why |
|---|---|---|---|
| Team rating | 1535 | 1447 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +14 | −20 | BOS: Jake Bennett: team allows 0.69 fewer runs than with its usual starter (≈7 weighted starts) · ATH: Gage Jump: team allows 1.01 more runs than with its usual starter (≈7 weighted starts) |
| Elo ratings | BOS +104 Elo | BOS 64.5% | |
| Market-implied ratings | BOS 58.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | BOS 59.2% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | BOS 58.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
