If MLB wants to attract fans, particularly younger ones to the playoffs, it needs a new hook. A proven catalyst that can take even the most mundane subject, say civics, and turn it into a topic of rabid enthusiasm for millennials. In short, they need Hamilton. Not Reds base stealer extraordinaire Billy, but Hamilton, the musical. Anything that can inspire pre-teen girls to conduct rap battles about America’s Founding Fathers can certainly generate enthusiasm for America’s Pastime.
