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 | MIL | ARI | Why |
|---|---|---|---|
| Team rating | 1526 | 1529 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +4 | −2 | MIL: Jose Quintana: team allows 0.22 fewer runs than with its usual starter (≈10 weighted starts) · ARI: Eduardo Rodriguez: team allows 0.10 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | ARI +15 Elo | ARI 52.2% | |
| Market-implied ratings | ARI 54.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | ARI 54.2% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | ARI 58.3% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
