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 | 1505 | 1511 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +5 | −6 | ARI: Anthony DeSclafani: team allows 0.27 fewer runs than with its usual starter (≈9 weighted starts) · TEX: Jack Leiter: team allows 0.29 more runs than with its usual starter (≈9 weighted starts) |
| Elo ratings | TEX +12 Elo | TEX 51.8% | |
| Market-implied ratings | TEX 54.6% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | TEX 54.2% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | TEX 58.6% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
