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 | LAA | Why |
|---|---|---|---|
| Team rating | 1516 | 1458 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −19 | −8 | SEA: Logan Evans: team allows 0.93 more runs than with its usual starter (≈7 weighted starts) · LAA: Yusei Kikuchi: team allows 0.40 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | SEA +30 Elo | SEA 54.3% | |
| Market-implied ratings | LAA 50.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | SEA 50.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | LAA 56.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
