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 | BAL | BOS | Why |
|---|---|---|---|
| Team rating | 1527 | 1493 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +8 | −2 | BAL: Albert Suarez: team allows 0.42 fewer runs than with its usual starter (≈9 weighted starts) · BOS: Kutter Crawford: team allows 0.10 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | BAL +26 Elo | BAL 53.8% | |
| Market-implied ratings | BOS 50.5% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | BAL 50.1% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | BOS 55.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
