William Boor’s Red Sox vs Royals Prediction, Betting Analysis
This isn't the most enticing pitching matchup on tonight's slate and although unders are typically associated with elite starting pitchers, we're making this play based on the weather. Let me explain.
When the wind is blowing in at a range between 5-35 mph, fly balls lose carry and home run rates drop significantly. So, this Bet Labs system targets unders in these conditions when games have an over/under between six and 11.
It’s a sharp, weather-based angle that exploits environmental factors that are often underweighted in line-setting, but that heavily affect scoring outcomes.
Red Sox vs. Royals fits all the parameters, so a play on the under is the sharp side tonight.
