A recurring topic of discussion in baseball is pace of play. Mound visits are being limited at the major league level this season, while the minors are experimenting with new extra-inning rules. The assumption underlying all of these changes is that baseball needs to shorten games to attract a millennial audience. As evidence, MLB will cite that the average MLB fan is 57 years old.
Except that is not what the statistic actually says. It actually says that the average television viewer of baseball is 57 years old.
