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 | ARI | LAD | Why |
|---|---|---|---|
| Team rating | 1507 | 1555 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +1 | +19 | ARI: Zac Gallen: team allows 0.04 fewer runs than with its usual starter (≈10 weighted starts) · LAD: Blake Snell: team allows 0.95 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | LAD +84 Elo | LAD 61.9% | |
| Market-implied ratings | LAD 64.1% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | LAD 63.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | LAD 65.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
