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 | ATH | Why |
|---|---|---|---|
| Team rating | 1502 | 1458 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +2 | +11 | ARI: Anthony DeSclafani: team allows 0.09 fewer runs than with its usual starter (≈9 weighted starts) · ATH: Jacob Lopez: team allows 0.55 fewer runs than with its usual starter (≈8 weighted starts) |
| Elo ratings | ARI +17 Elo | ARI 52.4% | |
| Market-implied ratings | ATH 50.0% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | ARI 50.3% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | ATH 54.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
