Colin Rea Takes the Mound for Chicago at Busch Stadium

Rea gets the assignment in a road divisional start, which is never a throwaway. The Cardinals lineup he is facing is built around contact and athleticism at the top, with legitimate run-producing threats in the middle of the order. No Cardinals starter has been named as of this writing, which adds a layer of uncertainty to Chicago's preparation, but the Cubs will need to be ready regardless of who takes the mound for St. Louis.

St. Louis Cardinals Lineup Analysis

The Cardinals are sending out a recognizable, capable group. Here is how manager Oliver Marmol has constructed Tuesday's lineup:

• JJ Wetherholt, 2B — leadoff
• Jordan Walker, RF — batting second
• Alec Burleson, 1B — batting third
• Iván Herrera, DH — cleanup spot
• Lars Nootbaar, LF — batting fifth
• Masyn Winn, SS — batting sixth
• Nathan Church, CF — batting seventh
• José Fermín, 3B — batting eighth
• Jimmy Crooks, C — batting ninth

Wetherholt and Walker give St. Louis speed and on-base ability at the top. Burleson at three and Herrera in the cleanup spot represent the Cardinals' primary run-production threat. Rea will need to work carefully around that middle of the order. Masyn Winn remains a dangerous bat capable of doing damage at any point in the count.

Keys to Watch for the Cubs on Tuesday

Rea's Command Against a Contact-Heavy Lineup

The Cardinals lineup is not built around walking and waiting. They put the ball in play. Rea's ability to generate weak contact and avoid big innings early will set the tone. If he can get through five or six innings cleanly, Chicago's bullpen can take it from there.

Cubs Offense Against an Unknown Starter

Not knowing who St. Louis is throwing creates an interesting dynamic. Chicago's hitters will need to stay disciplined through the first time through the order, read what the Cardinals' arm is offering, and make adjustments. First-inning approach matters here.

Divisional Urgency

Cubs-Cardinals games in late July are not background noise. Every game in this series has direct NL Central implications, and that is true whether you are chasing or holding ground.

Prediction

This one hinges on Rea. If he commands the strike zone and limits traffic against the Cardinals' contact-first lineup, the Cubs have a real shot on the road. The unknown Cardinals starter is a wildcard, but Chicago's offense is capable of making adjustments. Call it a close, competitive game — Cubs 4, Cardinals 3.
