The 2000 World Series was the 96th edition of Major League Baseball (MLB)'s championship series, and the conclusion of the 2000 Major League Baseball season. A best-of-seven playoff, it featured a crosstown matchup between the two-time defending World Series champions and American League (AL) champion New York Yankees and the National League (NL) champion New York Mets. The Yankees defeated the Mets four games to one to win their third consecutive championship and 26th overall. It marks, to date, the last World Series with a repeat champion. It was the first postseason Subway Series since 1956. The Yankees were in the World Series for the third consecutive season and fourth in the past five years, and 37th overall. This made it the most of any team in MLB. The Mets qualified to play in the World Series for the fourth time in franchise history, making this the most of any expansion franchise in MLB and its first since winning the 1986 World Series. This is the most recent World Series in which both participating teams had made the postseason the previous year.
