First pitch is scheduled for 7:15 p.m. at Busch Stadium.
While the Cardinals' record-setting power display captured all the headlines, the biggest binge of the night Thursday may not have happened without the deft steal of a newcomer to the starting lineup.
In the third inning, Oscar Mercado led off with a single. He stole second and, while initially ruled out on the field, was proven safe on a replay challenge.
What followed was a three-run homer by Willson Contreras to flip the game and then back-to-back-to-back homers by teammates that gave the Cardinals four of their Busch Stadium-record seven homers in a single inning.
