The Commercial Base Ball Club have their regular field exercise on Gamble Lawn this Saturday afternoon. Members are requested to be prompt in attendance, and Base Ball players generally are invited to the field.-Missouri Republican, June 18, 1864
This is really interesting. One of the last references to the Commercial Club in the Republican was in 1863 and it was in regards to their trying to get a clubhouse built at Lafayette Park. That request was taken to the Common Council, where it was placed in the hands of a subcommittee who forwarded it to the Board of Improvements. I'm not sure what happened after that. However, here we find the club holding their practice days at Gamble Lawn and that leads me to believe that the club's request was turned down. If they had been allowed to build a clubhouse at Lafayette Park, they would be playing at Lafayette Park. But they're not.
Also of interest is the general invitation that the club extended to all ball players. Why would they do that? Was the club short players? Was the war having a negative effect on the number of players in the city? Or was it just courtesy? Maybe they were just being nice but I'm not sure if I've ever seen an open invitation like that to a club's practice day.
