Our reading
An editorial interpretation.
Miranda's enthusiasm is for the baseball team, while the speaker likes the freedom surrounding the outing. Repeating huge fan makes those different motives sound equal. The joke openly admits that the speaker's pleasure comes from the setting rather than the sport.
