Orioles vs Cubs Preview
This has been a low-scoring series, and today's closing chapter should continue the trend due to weather conditions.
The first two games hit the under, producing a combined eight total runs on Friday and Saturday.
Today, Colin Rea will start for the Cubs and will try to take advantage of the wind to bounce back after a couple of rough outings.
Brandon Young will go to the mound for the Orioles after limiting the Blue Jays, the best offense since July 1st in MLB, to only two runs in six innings with six strikeouts in his previous start.
Our recommendation is to go with the under, based on the Wrigley Field Unders PRO system.
This system focuses exclusively on Cubs home games, where wind direction is a major scoring variable.
When wind blows in or across (in or from sides) and total opens between 8–13, unders become highly valuable.
Wrigley is uniquely sensitive to weather due to its field orientation. Since it has no dome, this makes it the premier ballpark for wind-based betting edges.
Pick: Under 8 (-110, BetMGM)
