The Kansas City Cowboys were admitted to the American Association on January 17, 1888, after the New York Metropolitans folded. The Brooklyn Dodgers purchased what remained of the Mets, hoping to obtain the services of the now-unemployed New York players. The Cowboys, meanwhile, would have a rough inaugural season, finishing with a 43-89 record, putting them in last place in the AA.
