What is dncss detroit bb con detroit mi ?

I had a charge on my credit card for dncss baltimore bb con. It took some detective work but I'm quite certain that it was for charges at the Baltimore Orioles game. Using my powers of deductive reasoning, I would like to hypothesize that you attended a Tigers baseball game and came across these charges on your credit card. 

YES!!! Thank you! i have been going crazy trying to figure out the last couple months of charges for CHICAGO...etc. and even the c/c company couldn't tell me. Mine would have been for White Sox games! Thank you both!

god knows what the dncc stands for? but followed by the name of your city then bb club or ret - It is charges that you made at your cities baseball stadium's retail or restaraunt credit card machines.  Who ever put the DNCC in front of it - makes no sense and it should be deleted as it leads to consumers having no idea where these charges originated from.
