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 | 1550 | 1540 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +1 | +2 | BOS: Alec Gamboa: team allows 0.05 fewer runs than with its usual starter (≈1 weighted starts) · NYY: Max Fried: team allows 0.12 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | NYY +9 Elo | NYY 51.3% | |
| Market-implied ratings | NYY 57.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | NYY 56.5% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | NYY 57.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
