Here's Facebook's 2015 MLB Fandom Map

It's that time of year again: time to nod our heads at the fact that baseball fandom is largely geographic, unless you're a goddamned Yankees fan.

Facebook has released its annual fandom map, color-coding each U.S. county and Canadian census division by which team has the most "likes." Click here for a much larger version of the map.

Definite second bananas in two-team metro areas, the Mets and Athletics don't take a plurality of any counties. (In other two-team markets, the Angels take a two-county swath of Southern California, and the White Sox actually win Chicagoland.)

But aside from fluke, small-sample-size exclaves, it's really only the Yankees that overspill their broadcast areas. Bandwagoning is a real thing, though. Facebook has created maps showing the spread of Giants and Royals fandoms since their pennant-winning seasons.
