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 | 1529 | 1520 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +11 | +12 | SEA: Bryan Woo: team allows 0.56 fewer runs than with its usual starter (≈9 weighted starts) · CLE: Tanner Bibee: team allows 0.62 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | CLE +9 Elo | CLE 51.4% | |
| Market-implied ratings | CLE 57.3% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CLE 56.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CLE 58.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
