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 | MIL | Why |
|---|---|---|---|
| Team rating | 1539 | 1543 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +4 | −1 | ARI: Merrill Kelly: team allows 0.18 fewer runs than with its usual starter (≈10 weighted starts) · MIL: Aaron Civale: team allows 0.03 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | MIL +18 Elo | MIL 52.6% | |
| Market-implied ratings | MIL 50.7% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | MIL 51.0% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | ARI 51.1% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
