Two new teams were added to the American League at the same time: the Los Angeles Angels (who soon moved from downtown L.A. to nearby Anaheim) and a new Washington Senators franchise.
Do Americkej ligy boli v rovnakom čase pridané dve mužstvá: Los Angeles Angels (ktoré sa čoskoro z centra L.A. presťahovali do blízkeho Anaheim) a nové mužstvo "druhí" Washington Senators.
