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 | LAA | Why |
|---|---|---|---|
| Team rating | 1515 | 1456 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +20 | +7 | ARI: Ryne Nelson: team allows 1.00 fewer runs than with its usual starter (≈10 weighted starts) · LAA: Tyler Anderson: team allows 0.33 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | ARI +54 Elo | ARI 57.8% | |
| Market-implied ratings | LAA 50.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | ARI 50.8% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | LAA 50.0% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
