Q:Information:  - The World Series is the annual championship series of Major League Baseball (MLB) in North America, contested since 1903 between the American League (AL) champion team and the National League (NL) champion team. The winner of the World Series championship is determined through a best-of-seven playoff, and the winning team is awarded the Commissioner's Trophy. As the series is played in October (and occasionally November), during the autumn season in North America, it is often referred to as the Fall Classic.  - The National League of Professional Baseball Clubs, known simply as the National League (NL), is the older of two leagues constituting Major League Baseball (MLB) in the United States and Canada, and the world's oldest current professional team sports league. Founded on February 2, 1876, to replace the National Association of Professional Base Ball Players, it is sometimes called the Senior Circuit, in contrast to MLB's other league, the American League, which was founded 25 years later. Both leagues currently have 15 teams. The two league champions of 1903 arranged to compete against each other in the inaugural World Series. After the 1904 champions failed to reach a similar agreement, the two leagues formalized the World Series as an arrangement between the leagues. National League teams have won 48 of the 112 World Series contested from 1903 to 2016. The 2016 National League champions are the Chicago Cubs.  - The National Association of Base Ball Players (NABBP) was the first organization governing American baseball. The first convention of sixteen New York City area clubs in 1857 practically terminated the Knickerbocker era, when that club privately deliberated on the rules of the game. The last convention, with hundreds of members represented only via state associations, provoked the establishment of separate professional and amateur associations in 1871. The succeeding National Association of Professional Base Ball Players is considered the first professional sports league; through 1875 it governed professional baseball and practically set playing rules for all. Because the amateur successor never attracted many members and it convened only a few times, the NABBP is sometimes called "the amateur Association" in contrast to its professional successor.  - A professional is a member of a profession or any person who earns their living from a specified professional activity. The term also describes the standards of education and training that prepare members of the profession with the particular knowledge and skills necessary to perform their specific role within that profession. In addition, most professionals are subject to strict codes of conduct, enshrining rigorous ethical and moral obligations. Professional standards of practice and ethics for a particular field are typically agreed upon and maintained through widely recognized professional associations, such as the IEEE. Some definitions of "professional" limit this term to those professions that serve some important aspect of public interest and the general good of society.  - The National Association of Professional Base Ball Players (NAPBBP), or simply the National Association (NA), was founded in 1871 and continued through the 1875 season. It succeeded and incorporated several professional clubs from the National Association of Base Ball Players (NABBP); in turn several of its clubs created the succeeding National League of Professional Baseball Clubs.  - The American League of Professional Baseball Clubs, or simply the American League (AL), is one of two leagues that make up Major League Baseball (MLB) in the United States and Canada. It developed from the Western League, a minor league based in the Great Lakes states, which eventually aspired to major league status. It is sometimes called the Junior Circuit because it claimed Major League status for the 1901 season, 25 years after the formation of the National League (the "Senior Circuit").  - At the end of each Major League Baseball season, the league leaders of various statistical categories are announced. Leading the league in a particular category is referred to as a "title".  - Baseball is a bat-and-ball game played between two teams of nine players each, who take turns batting and fielding.  - The City of New York, often called New York City or simply New York, is the most populous city in the United States. With an estimated 2015 population of 8,550,405 distributed over a land area of just , New York City is also the most densely populated major city in the United States. Located at the southern tip of the state of New York, the city is the center of the New York metropolitan area, one of the most populous urban agglomerations in the world. A global power city, New York City exerts a significant impact upon commerce, finance, media, art, fashion, research, technology, education, and entertainment, its fast pace defining the term "New York minute". Home to the headquarters of the United Nations, New York is an important center for international diplomacy and has been described as the cultural and financial capital of the world.  - The Chicago Cubs are an American professional baseball team based in Chicago, Illinois. The Cubs compete in Major League Baseball (MLB) as a member club of the National League (NL) Central division, where they are the defending World Series champions. The team plays its home games at Wrigley Field, located on the city's North Side. The Cubs are one of two major league teams in Chicago; the other, the Chicago White Sox, is a member of the American League (AL) Central division. The team, first known as the White Stockings, was a founding member of the NL in 1876, becoming the Chicago Cubs in 1903.  - Chicago (or ), officially the City of Chicago, is the third-most populous city in the United States, and the fifth-most populous city in North America. With over 2.7 million residents, it is the most populous city in the state of Illinois and the Midwestern United States, and the county seat of Cook County. The Chicago metropolitan area, often referred to as Chicagoland, has nearly 10 million people and is the third-largest in the U.S.  - The Mutual Base Ball Club of New York was a leading American baseball club almost throughout its 20 - year history . It was established during 1857 , the year of the first baseball convention , just too late to be a founding member of the National Association of Base Ball Players . It was a charter member of both the first professional league in 1871 and the National League in 1876 . Failing on the field and in the coffer , it declined to make its last western trip of the inaugural season . For the transgression it was expelled in December , and soon found itself defunct . The Mutual club initially played its home games at Elysian Fields in Hoboken , with the New York Knickerbockers and many other Manhattan clubs , but moved to the enclosed Union Grounds in Brooklyn in 1868 . The Mutuals chose open professionalism in 1869 -- 70 after NABBP liberalization . They joined the first professional league , the National Association of Professional Base Ball Players , for its 1871 to 1875 duration . In 1876 , the Chicago White Stockings initiated the National League and recruited its members from West to East , partly to wrest control of professional baseball from Eastern interests . The Mutuals were one of eight charter members , six of whom were from the National Association . Weak ( sixth place at 21 -- 35 ) and cash - poor , the club refused to complete its playing obligations in the West ; and was expelled . On May 13 , 1876 , the Mutuals executed the first triple play in major - league history in a game against the Hartford Dark Blues . Union Grounds proprietor William Cammeyer , often listed today as the Mutual club owner , signed the Hartford Dark Blues to play at his Union Grounds in 1877 . The team was effectively a one - year replacement for the defunct Mutuals , and was sometimes called `` Hartford of Brooklyn '' .
