1989 World Series: 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.

2010 Texas Rangers season: The Texas Rangers' 2010 season was the 50th in franchise history.  The team, managed by Ron Washington, won their first division title since 1999 and reached the World Series for the first time in only their fourth playoff appearance.  Washington would become only the second manager in franchise history to lead the Rangers to the post season and the first to ever win a post season series.  They would win the American League pennant by defeating the defending World Series champions, the New York Yankees in six games in the ALCS.  In the World Series, they lost to the San Francisco Giants in five games.

1954 World Series: The 1954 World Series matched the National League champion New York Giants against the American League champion Cleveland Indians.  The Giants swept the Series in four games to win their first championship since , defeating the heavily favored Indians, who had won an AL-record 111 games in the regular season; it has since been broken by the 1998 New York Yankees (114) and again by the 2001 Seattle Mariners (116, tying the 1906 Chicago Cubs for the most wins ever).  The Series is perhaps best-remembered for "The Catch", a sensational running catch made by Giants center fielder Willie Mays in Game 1, snaring a long drive by Vic Wertz near the outfield wall with his back to the infield.  It is also remembered for utility player Dusty Rhodes' clutch hitting in three of the four games, including his walk-off hit for Monte Irvin that won Game 1, probably the best-known hit to be described as a "Chinese home run", since it barely cleared the 258 ft right-field fence at the Polo Grounds.  Giants manager Leo Durocher, who had managed teams to three National League championships, won his first and only World Series title in his managerial career.  After moving West, the San Francisco Giants would not win a World Series until the 2010 season.

2015 World Series: 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.

Curse of Coogan's Bluff: The Curse of Coogan's Bluff (1958–2010) was a baseball-related superstition that allegedly prevented the San Francisco Giants Major League Baseball franchise from winning the World Series following the club's move from New York City to San Francisco after the conclusion of the 1957 season.  The curse began when upset Giants fans in the New York metropolitan area placed a hex on the relocated franchise.  The curse ended when the Giants won the 2010 World Series in their fourth World Series appearance since the move to San Francisco.

2014 World Series: 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.

Their World Series sweep was the first by a National League team since the Cincinnati Reds swept the Oakland Athletics in the 1990 series and the first NL sweep not by the Reds since 1963, when the Los Angeles Dodgers swept the New York Yankees.  The Giants' Pablo Sandoval, who in Game 1 tied a record by hitting three home runs in one World Series game, two off of Tigers' ace Justin Verlander, was named the World Series Most Valuable Player (MVP).
