The New York Yankees don’t have too many concrete rivals other than the Boston Red Sox. Perhaps the only other full-time rival the Yankees really have is their crosstown adversaries, the New York Mets. The competitive history between these two teams only dates back 21 years to 1997, when inter-league play was first invented.
The Yankees have gone 72-48 against the Mets in 120 all-time meetings, including the postseason. However, both teams have gotten some good shots in over the years, and there has never been a shortage of entertainment. Even now, with the Mets in last place, the games feature a bevy of big-name players.
