Cubs vs. Cardinals: Trade Tonight's Opener
Chicago (60-46) marches into St. Louis (53-53) holding the top National League Wild Card spot, six games back in the NL Central. Colin Rea takes the mound for the Cubs against Cardinals righty Michael McGreevy. Pete Crow-Armstrong leads Chicago with 23 home runs and a .288 average, while Jordan Walker powers St. Louis with 22 homers of his own.
The Cardinals hold a slim 4-3 edge in the season series, and Nico Hoerner enters red-hot for Chicago after a scorching stretch over his last 10 games. Crow-Armstrong's power and Hoerner's hot bat give Cubs backers plenty to weigh, while McGreevy's 3.07 ERA rewards anyone leaning toward a low-scoring night.
