The St. Louis Cardinals, a professional baseball franchise based in St. Louis, Missouri, compete in the National League (NL) of Major League Baseball (MLB).
 Prior to entering the NL in 1892, they were also a member of the American Association (AA) from 1882 to 1891.
 They have won 11 World Series titles as an NL team, one pre-World Series championship and tied another against the NL.
 Since 1900, the team has been known as the Cardinals.
 They were originally named the Perfectos.
 Baseball teams like St. Louis employ a manager to make on-field decisions for the team during the game, similar to the head coach position of other sports.
 A number of coaches report to the manager, including the bench coach, first and third base coaches, and pitching and hitting coaches, among other coaches and instructors.
 Mike Matheny, a former catcher for the Cardinals from 2000 to 2004, has been the manager since 2012.
 He is signed through 2017.
The 1966 World Series matched the American League (AL) champion Baltimore Orioles against the defending World Series champion and National League (NL) champion Los Angeles Dodgers, with the Orioles sweeping the Series in four games to capture their first championship in franchise history.
 It was also the last World Series played before Major League Baseball (MLB) introduced the Commissioner's Trophy the following year.
The 2014 San Francisco Giants season was the Giants' 132nd year in Major League Baseball, their 57th year in San Francisco since their move from New York following the 1957 season, and their 15th at AT&T Park.
 The Giants finished the season in second place in the National League West, but qualified for the playoffs and defeated the Pittsburgh Pirates in the National League Wild Card Game and the Washington Nationals in the National League Division Series.
 They defeated the St. Louis Cardinals in the National League Championship Series in five games and beat the Kansas City Royals in seven games in the 2014 World Series, their third World Series win in five years.
The 2015 San Francisco Giants season was the Giants' 133rd year in Major League Baseball, their 58th year in San Francisco since their move from New York following the 1957 season, and their 16th at AT&T Park.
 The team entered the season as the defending World Series champions and got second place in the NL West for the second straight year, but missed the playoffs with a record of 84-78 (.519).
The 1989 World Series was the 86th edition of Major League Baseball's championship series, and the conclusion of the 1989 Major League Baseball season.
 A best-of-seven playoff, it was played between the American League (AL) champion Oakland Athletics and the National League (NL) champion San Francisco Giants.
 The Series ran from October 14 through October 28, with the Athletics sweeping the Giants in four games.
 It was the first World Series sweep since 1976.
 The four game sweep by the Athletics at the time would mark only the third time in World Series history that a team never trailed in any game (1963, 1966, and 2004 World Series being the only other times this occurred), and the first in the playoff era (post-1968).
 Until 2015, this was the last time a team would win the World Series after losing in the previous year.
The 2014 World Series was the 110th edition of the Major League Baseball (MLB) championship series, a best-of-seven playoff between the National League (NL) champion San Francisco Giants and the American League (AL) champion Kansas City Royals.
 The Giants defeated the Royals four games to three to clinch their third World Series championship in a five-season span (2010–14), and their third overall since the club's move to San Francisco from New York.
 It was the Giants' eighth World Series championship in franchise history.
The 2015 World Series was the 111th edition of Major League Baseball's championship series, 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 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.
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.
