"Orioles" is a traditional name for baseball clubs in Baltimore (after the state bird of Maryland, with the colors of black and orange/gold/yellow).
 It was used by major league teams representing the port city from 1882 through 1899 in the old American Association and the original National League two decades after its founding in 1876, and by a charter team franchise member of the new American League from 1901 through 1902.
 The American League franchise was later shifted against the city's will to New York City with former famous player and now owner/manager John McGraw in 1903 and renamed the New York Highlanders, which later became the modern New York Yankees, a decade later (in order to give the new A.L. "bragging rights" by also having a team in the "Big Apple" versus the New York Giants and the Brooklyn Dodgers).
 Their string of championships and hall-of-fame roster of players began in the "Roaring Twenties", some baseballers say with the trading of the now famous "Babe Ruth", the "Bambino", and "Sultan of Swat", George Herman Ruth of southwest Baltimore, (formerly briefly with the old, now minor league Orioles of the International League with owner/manager Jack Dunn (1878–1928) in 1914, then traded later in the season to the Boston Red Sox because of new Federal League competition from the neighboring Baltimore Terrapins) now from the also financially pressed Red Sox team in 1919 to the New York Yankees.
 Since 1923, the Yankees have compiled 27 World Series championships (with the St. Louis Cardinals being second, having won 11 between 1926 and 2011), and the 1980s are the only decade so far in which they have failed to win at least one title.
The 2004 Boston Red Sox season was the 104th season in the franchise's Major League Baseball history.
 Managed by Terry Francona, the Red Sox finished with a 98–64 record, three games behind the New York Yankees in the American League East.
 The Red Sox qualified for the postseason as the AL wild card, swept the Anaheim Angels in the ALDS, and faced the Yankees in the ALCS for the second straight year.
 After losing the first three games to the Yankees and trailing in the ninth inning of the fourth game, the Red Sox became the first team in major league history to come back from a three-game postseason deficit, defeating the Yankees in seven games.
 The Red Sox then swept the St. Louis Cardinals in the World Series, capturing their first championship since 1918.
The New York Yankees' 2004 season was the 102nd season for the Yankees.
 The Yankees opened the season by playing two games against the Tampa Bay Devil Rays in Japan on March 30, 2004.
 The team finished with a record of 101-61, finishing 3 games ahead of the Boston Red Sox in the AL East.
 The 2004 season was the Yankees third straight season of 100+ wins, the first such instance in franchise history.
 New York was managed by Joe Torre.
 In the playoffs, the Yankees defeated the Minnesota Twins, 3 games to 1, in the ALDS, before losing to the wild card Boston Red Sox, 4 games to 3, in the ALCS.
 The 2004 Yankees are notable as the only team in MLB history to lose a 7-game playoff series after taking a 3 games to none lead.

The Yankees–Red Sox rivalry is a Major League Baseball (MLB) rivalry between the New York Yankees and Boston Red Sox.
 The two teams have competed in MLB's American League (AL) for over 100 seasons and have since developed one of the fiercest rivalries in American sports.
 In 1919, Red Sox owner Harry Frazee sold star player Babe Ruth to the Yankees, which was followed by an 86-year period in which the Red Sox did not win a World Series.
 This led to the popularization of a superstition known as the "Curse of the Bambino", which was one of the most well-known aspects of the rivalry.
