The 2000 Major League Baseball season ended with the New York Yankees defeating the New York Mets in five games, for their third consecutive World Series title. The 2000 World Series was known as the Subway Series because both fans and the two teams could take the subway to and from every game of the series.
A then-record 5,693 home runs were hit during the regular season in 2000 (the record was broken in 2017, when 6,105 home runs were hit). Ten teams hit at least 200 home runs each, while for the first time since 1989 and only the fifth since 1949 no pitcher pitched a no-hitter.[a] Also, no team reached 100 in either the win or loss column.
The separate American and National League offices were dissolved; with this, the league became a single unified organization. As a result, the separate umpiring crews for each league were also dissolved; all umpiring crews now worked throughout the league.
