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 | CHW | Why |
|---|---|---|---|
| Team rating | 1500 | 1409 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +6 | −13 | BOS: Tanner Houck: team allows 0.31 fewer runs than with its usual starter (≈10 weighted starts) · CHW: Jake Woodford: team allows 0.66 more runs than with its usual starter (≈6 weighted starts) |
| Elo ratings | BOS +93 Elo | BOS 63.0% | |
| Market-implied ratings | BOS 62.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | BOS 62.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | BOS 68.9% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
