The major sports trifecta, which happens when 3 professional sports teams in the same region win a championship within a season of one another, is extremely rare. This achievement has occurred twice:
New York City 1927-1928: New York Yankees (MLB 1927), New York Giants (NFL 1927), and New York Rangers (NHL 1928).
Detroit 1935-1936: Detroit Tigers (MLB 1935), Detroit Lions (NFL 1935), and Detroit Redwings (NHL 1936).
