New York Mets
The current New York Mets name goes back to the original Metropolitan Baseball Club which was a member of the 19th Century American Association, a club which lasted until 1887.
They were normally listed as "Metropolitan" in the standings, and writers would sometimes use the pluralized "Metropolitans" in the style of the day, to distinguish them from the "New Yorks" Giants.
When Major League Baseball expanded in 1962, the old name was revived in the form of the Metropolitan Baseball Club of New York, otherwise known as the New York Mets.
"Met" is a common short form of "Metropolitan", as in "The Met" for the Metropolitan Opera; or "MetLife" for the Metropolitan Life Insurance Company.
