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 | TEX | ARI | Why |
|---|---|---|---|
| Team rating | 1520 | 1512 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −14 | +3 | TEX: Patrick Corbin: team allows 0.69 more runs than with its usual starter (≈10 weighted starts) · ARI: Ryne Nelson: team allows 0.13 fewer runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | ARI +27 Elo | ARI 53.8% | |
| Market-implied ratings | ARI 54.3% | 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 56.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
