Cubs vs Cardinals Prediction, Betting Analysis
This system capitalizes on an overlooked weather edge in MLB totals betting. It focuses on regular-season games where elevated humidity — ranging from 45 to 95 — intersects with moderate temperatures and neutral wind patterns.
Despite assumptions that humidity boosts offense, public bettors are fading these conditions, which actually correlate with suppressed scoring in certain environments. In these spots, the home team has stayed under in recent games, with their five-game over rate sitting below 40, suggesting low offensive rhythm.
The market has subtly corrected as well, with the total dropping from open to close, and the overall percentage of bets on the over remains modest — between 6 and 29. These indicators combine to identify under-the-radar under spots where public narratives misalign with actual scoring trends.
Pick: Under 8.5 (+100, BetMGM)
