Cricket is obviously not baseball but the cricket references that we have from the 1850s gives us the best look at the culture of bat and ball games in St. Louis that we have for the period before the advent of the New York game in the city. We have clubs, grounds, matches, and crowds coming out to see the game. While I'm certain that a variant of baseball was being played in the city at the time, I haven't found this level of information about that game that I see with cricket.
