The Chicago Cubs face the St. Louis Cardinals in the opener of a 4-game set at Busch Stadium in St. Louis Monday.

Note: With extreme heat forecasted throughout the week—particularly in St. Louis—fans attending games should take precautions. Stay hydrated, wear lightweight clothing, and seek shade or cooling areas when needed. If you’re heading to the ballpark, don’t forget sunscreen and take frequent breaks to avoid heat-related illness.
