July 10, 1968 – The National League of Major League Baseball announced that it would split into 2 divisions of six teams each for the 1969 season. The decision came after the American League separated its teams into divisions in a similar fashion. Warren Giles, President of the NL stated that New York, Philadelphia, Pittsburgh, St Louis, and the expansion team from Montreal would comprise one group. At the same time, San Francisco, LA, San Diego, Cincinnati, Houston, and Atlanta would round out group 2.
As a compromise, the American League increased their scheduled games to 162 from 156 to match the NL so that consistency would be between the two opposing Leagues. The NL would move to three geographical divisions in 1994 as the Colorado Rockies and Florida Marlins had been recently added and the Milwaukee Brewers moved over from the AL.
