 The tone of baseball rivalries changed in the early 1990s; fraternization between players who had moved to different teams or knew each other from various ventures kept baseball rivalries to a "friendly" level.However, Major League Baseball's 1994 divisional re-alignment solidified the rivalry between the Phillies and Mets.The Pittsburgh Pirates, former members of the National League East and in-state rivals of the Phillies, moved into the newly created National League Central Division, and the Atlanta Braves, former members of the National League West, entered the division.
