Before today’s game the Cardinals added 8 players to the roster. You can get caught up on all the roster moves by checking out my article here. The Reds added 5 players too, and both squads have 17 pitchers. The Cards have an 8-man bench and the Reds have a 5-man bench for this doubleheader, with the Cards at 33 players on the roster and the Reds at 30.
After last night’s walkoff win in Game 2 of yesterday’s doubleheader, the Cards were looking to do it again. I talk about the Cardinals history of back-to-back doubleheaders in an article here.
