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 | SEA | CLE | Why |
|---|---|---|---|
| Team rating | 1512 | 1509 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −7 | −3 | SEA: Emerson Hancock: team allows 0.36 more runs than with its usual starter (≈10 weighted starts) · CLE: Gavin Williams: team allows 0.13 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | CLE +20 Elo | CLE 52.9% | |
| Market-implied ratings | CLE 52.2% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CLE 52.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CLE 53.2% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
