Major League Soccer (MLS) is set to implement a significant calendar change, transitioning to a summer-to-spring schedule starting in 2027. This shift aims to align the league more closely with major European football leagues and the global transfer window, while also reducing clashes with FIFA international fixtures. The new format will kick off with a "Sprint Season" on February 19, 2027, featuring Lionel Messi’s Inter Miami facing FC Cincinnati at Nu Stadium in Miami. Each club will play a 14-match regular season, concluding on May 8 with "Decision Day," which includes the Hudson River Derby between New York City FC and the New York Red Bulls. Another notable fixture is the ‘El Trafico’ derby on April 10 between LA Galaxy and Los Angeles FC. The first full season under this revised calendar will run from mid-to-late July 2027 to May 2028, incorporating a winter break in January. MLS Commissioner Don Garber and United States men’s national team coach Mauricio Pochettino have both endorsed this strategic move, highlighting its benefits for player development and club operations.
