1860s--Sandlot baseball originated in what is now the greater Civic Center area in the 1860s. First California team organized in Dan's Oyster saloon on Montgomery St.. They elected officers, held regular meetings, went on drinking together, "but never did get around to playing a game."
Feb. 22, 1860--California's first official ballgame played in San Francisco.
In 1924, Anita Day Hubbard wrote an epic series of articles in the SF Call Bulletin on the history of the city and the Mission which contain a staggering amount of historical detail, including these detailed paragraphs on baseball:
1869--Cincinnati Red Stockings arrive on first transcontinental commercial rail run, win all games played in San Francisco. They were the baseball team of the day. In September 1869, at Folsom and 25th, they proceeded to blow out our Eagles 35-4 on the 25th. The Eagles dusted off and… lost again. Even more badly, 58-4.
