St. Louis Cardinals vs Chicago Cubs Picks and Prediction

Pick: Chicago Cubs Moneyline

Chicago is the preferred side because of its superior offense, strong home record and slight starting pitching edge. The Cubs have produced 634 runs compared with 529 for St. Louis, and their .339 on-base percentage gives them a meaningful advantage in creating scoring opportunities. With Chicago also sitting 20 games above .500 and 35-24 at home, the Cubs are the stronger moneyline play.

Pick: Under 8.5

Take the under if the total is set at 8.5. Both scheduled starters enter with ERAs of 3.64 or better and matching 1.22 WHIPs, which gives this matchup a solid foundation for a lower-scoring game. Chicago owns the stronger offense, but St. Louis has allowed only one run across its last two completed games, making the Under the preferred total angle.
