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 | HOU | CHW | Why |
|---|---|---|---|
| Team rating | 1496 | 1488 | Elo entering the game; 1500 is league average |
| Home field | — | +18 | Worth 18 Elo in MLB |
| Starting pitchers | +5 | −3 | HOU: Ronel Blanco: team allows 0.24 fewer runs than with its usual starter (≈10 weighted starts) · CHW: Erick Fedde: team allows 0.14 more runs than with its usual starter (≈10 weighted starts) |
| Elo ratings | CHW +3 Elo | CHW 50.4% | |
| Market-implied ratings | CHW 50.4% | Team strength as past closing lines priced it, same game context | |
| Pre-line forecast | CHW 50.4% | 15% Elo, 85% market-implied (log-odds blend) | |
| Forecast | CHW 52.7% | Follows the market (vig removed): in testing, adding the ratings made it less accurate | |
