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 | MIL | Why |
|---|---|---|---|

| Starting pitchers | −5 | −10 | BOS: Richard Fitts: team allows 0.25 more runs than with its usual starter (≈5 weighted starts) · MIL: Aaron Civale: team allows 0.52 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | MIL +33 Elo | MIL 54.7% | |
| Market-implied ratings | MIL 51.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | MIL 52.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | MIL 51.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
