The New York Yankees and New York Mets have an interesting relationship. Because they do not play in the same league, I would not, strictly speaking, call them rivals. Although their annual Subway Series battles figuratively set the city ablaze — and sometimes have the appearance of a true rivalry — the relationship between the two teams is more akin to one between an older and a younger sibling. Even so, the “rivalry” has produced many amazing moments, the most famous naturally being the 2000 World Series, the first time two New York teams met in the World Series since 1956.
