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 | BAL | Why |
|---|---|---|---|
| Team rating | 1537 | 1496 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +4 | +12 | BOS: Jake Bennett: team allows 0.19 fewer runs than with its usual starter (≈8 weighted starts) · BAL: Brandon Young: team allows 0.59 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | BOS +15 Elo | BOS 52.2% | |
| Market-implied ratings | BOS 55.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | BOS 54.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | BOS 52.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
