インターリーグ
Before the creation of Interleague play, teams from the National League never played teams from the American League in official games except during the All-Star Game and the World Series. The teams occasionally met in spring training exhibition games and from 1963 to 1983 they played annually in the Mayor's Trophy Game, an in-season exhibition game, where the Yankees posted a record of 10–8–1 over the Mets.
