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 | TEX | Why |
|---|---|---|---|
| Team rating | 1506 | 1510 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | −1 | −8 | ARI: Zac Gallen: team allows 0.05 more runs than with its usual starter (≈10 weighted starts) · TEX: Merrill Kelly: team allows 0.40 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | TEX +14 Elo | TEX 52.1% | |
| Market-implied ratings | TEX 58.9% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TEX 57.9% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | TEX 57.4% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
