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 | NYY | Why |
|---|---|---|---|
| Team rating | 1513 | 1553 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +5 | +8 | BOS: Ranger Suarez: team allows 0.27 fewer runs than with its usual starter (≈10 weighted starts) · NYY: Cam Schlittler: team allows 0.40 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | NYY +61 Elo | NYY 58.8% | |
| Market-implied ratings | NYY 59.3% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | NYY 59.2% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | NYY 57.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
