Which of the World Series were more than seven games?

Until the formation of the American Association in 1882 as a second major league, the National Association of Professional Base Ball Players (1871-1875) and then the National League (founded 1876) represented the top level of organized baseball in the United States. All championships were awarded to the team with the best record at the end of the season, without a postseason series being played. From 1884 to 1890, the National League and the American Association faced each other in a series of games at the end of the season to determine an overall champion. These series were disorganized in comparison to the modern World Series, with the terms arranged through negotiation of the owners of the championship teams beforehand. The number of games played ranged from as few as three in 1884 (Providence defeated New York three games to zero), to a high of fifteen in 1887 (Detroit beat St. Louis ten games to five). Both the 1885 and 1890 Series ended in ties, each team having won three games with one tie game.[5]

The series was promoted and referred to as "The Championship of the United States",[6][7] "World's Championship Series", or "World's Series" for short. In his book Krakatoa: The Day the World Exploded: August 27, 1883, Simon Winchester mentions in passing that the World Series was named for the New York World newspaper,[8] but this view is disputed.[9]

The 19th-century competitions are, however, not officially recognized as part of World Series history by Major League Baseball, as it considers 19th-century baseball to be a prologue to the modern baseball era.
