It’s another classic "Wrigley Wind" day on the North Side.

The weather report is calling for strong winds blowing directly in from center field at Wrigley on Wednesday afternoon during the Chicago Cubs MLB game with the Milwaukee Brewers.

Combine that with temperatures in the low-50s and high-40s, and we should see a significantly suppressed run-scoring environment.

Chicago Cubs vs Milwaukee Brewers Prediction: Wrigley Field Wind Betting System

As you might know, betting Unders at Wrigley where the wind is either blowing in or cross-field is historically very profitable.

We have an Action PRO System dedicated to tracking this exact phenomenon.

Action PRO System: Wrigley Field Unders

Since 2005, when the wind is blowing either in or cross-field at Wrigley, the Under is 304-201-27, a 60% win rate providing a 16% ROI.

As written by our own Evan Abrams:

This System focuses exclusively on Cubs home games, where wind direction is a major scoring variable. When the wind blows in or across (from the sides), and the total opens between eight and 13, Unders become highly valuable. Wrigley is uniquely sensitive to weather due to its field orientation and lack of a dome, making it the premier ballpark for wind-based betting edges.

Between the wind direction and the low-50s temperatures, BallParkPal's weather model projects a -24% run-scoring factor for today's game, lowering his projected total by 2.15 runs compared to a weather-neutral day.
