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 | NYY | BOS | Why |
|---|---|---|---|
| Team rating | 1555 | 1502 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +4 | −15 | NYY: Marcus Stroman: team allows 0.22 fewer runs than with its usual starter (≈10 weighted starts) · BOS: Kutter Crawford: team allows 0.76 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | NYY +55 Elo | NYY 57.8% | |
| Market-implied ratings | NYY 56.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | NYY 56.6% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | NYY 57.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
