The New York Mets and Houston Astros aren’t really rivals anymore like they could have been. Each was an expansion team in 1962, linking the pair. Back then, the Houston team went by the nickname, Colt .45s.
Now as the Astros and in the American League, the two only face each other once every few seasons. Thank goodness because their franchise is an absolute powerhouse in modern times.
Long before Jose Altuve, George Springer, and the ageless Justin Verlander were pitching in Houston, the Mets and Astros went to battle in the 1986 NLCS.
