A baseball “Subway Series” is when a New York National League team (such as the New York Mets, but also formerly the Brooklyn Dodgers and the New York Giants) plays the New York American League team (the New York Yankees) in the World Series. Since 1997, the term “Subway Series” has also applied to interleague play during the regular season.
However, the blog Uncle Mike’s Musings: A Yankees Blog and More insists that “Subway Series” is strictly for a World Series, and that interleague play during the regular season is a “City Series.” Not all sportswriters follow this distinction.
Wikipedia: Subway Series
The Subway Series is a series of Major League Baseball (MLB) rivalry games played between teams based in New York City; every historic and current venue for such games has been accessible via the New York City Subway, hence the name of the series.
The term’s historic usage has been in reference to World Series games played exclusively between the city’s teams. The New York Yankees have appeared in all Subway Series games as they have been the only American League (AL) team based in the city, and have compiled an 11–3 all-time series record in the 14 championship Subway Series.
Since 1997, the term Subway Series has been applied to interleague play during the regular season between the Yankees and New York City’s National League (NL) team: the New York Mets. The Mets and Yankees also played each other in the 2000 World Series.
In addition to the five World Series played between the Yankees and Giants before 1940, the two teams also played exhibition series against each other from time to time. The match-ups were known as the “City Series” and were sometimes played in October while other teams played in the World Series. However, after 1940, this became difficult because the Yankees would routinely appear in the World Series. In the 17 years from 1941 to 1957 (after which the Giants and Dodgers left New York City for California), the Yankees appeared in the World Series 12 times, failing to reach the Series only in 1944, 1945, 1946, 1948, and 1954.

Remember, kids: This is a City Series. It’s not a “Subway Series” unless it’s a World Series. http://unclemikesmusings.blogspot.com/2013/05/how-to-be-yankee-fan-at-citi-field-2013.html …

How to Go to a Mets Game—2016 Edition
This is the 8th season that Citi Field has been in operation, so, if you live anywhere in the Northeastern United States and love baseball, you should have gone at least once by now—as a neutral observer, if not in a City Series game.
Yes, “City Series.” It’s only a “Subway Series” if it’s a World Series. Nobody called it a “Subway Series” when the New York Giants played the Brooklyn Dodgers in a regular-season game up until 1957. Nor did they call it a “Subway Series” when they played each other in the 1951 National League Playoff.
