The 111th edition of the World Series, it was a best - of - seven playoff between the National League (NL) champion New York Mets and the American League (AL) champion Kansas City Royals . The series was played between October 27 and November 1, with the Royals winning the series 4 games to 1 . It was the first time since the 2010 World Series that the World Series extended into November . The Royals became the first team since the Oakland Athletics in the 1989 World Series to win the World Series after losing in the previous year . It was the first World Series to feature only expansion teams and the first since the 2007 World Series to not feature the Philadelphia Phillies, St. Louis Cardinals, or San Francisco Giants as the NL champions . </P> <P> The Royals had home field advantage for the first two games of the series because of the AL's 6--3 victory in the Major League Baseball All - Star Game . It was the 13th World Series in which home field advantage was awarded to the league that won the All - Star Game, a practice that was discontinued after the 2016 season . The series was played in a 2--3--2 format: the Royals hosted Games 1 and 2, and the Mets hosted Games 3, 4, and 5 (there was no Game 6 or 7, which the Royals would have hosted). </P>
