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 | 1503 | 1547 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −16 | +2 | BOS: Kutter Crawford: team allows 0.81 more runs than with its usual starter (≈10 weighted starts) · BAL: Corbin Burnes: team allows 0.09 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | BAL +80 Elo | BAL 61.4% | |
| Market-implied ratings | BAL 59.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | BAL 59.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | BAL 62.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
