The best explanation I've got is that Bruce Chen was curious. He knows all about the Minnesota stereotype, so he thought he'd put it to the test, entertainment value of the baseball game be damned. Bruce Chen was experimenting. Which could be an isolated instance, or which could signal the beginning of an uncomfortable era. For years, fans have been going to baseball games to observe baseball players. If baseball players start going to baseball games in part to observe the fans, then shit's gonna get awful meta, awful quick.
