United States cities with teams from four major league sports
Open-knowledge reference entry

There are 12 United States metropolitan areas that are home to teams that compete in each of the four major professional sports leagues in the United States and Canada: Major League Baseball (MLB), the National Basketball Association (NBA), the National Football League (NFL), and the National Hockey League (NHL). These leagues are sometimes called the "Big Four", in reference to their prominent position in North American sports.
Only the country's two largest metropolitan areas—New York and Los Angeles—have at least two teams in each major sports league.

Why this record matters
The phrase “open-knowledge reference entry” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 2, 2026. The linked authority identifier is Q17039038. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1972 and 1980.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
