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 also the first World Series 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>
