Context: Baseball is a bat-and-ball game played between two teams of nine players each, who take turns batting and fielding., In baseball, a wild pitch (abbreviated WP) is charged against a pitcher when his pitch is too high, too short, or too wide of home plate for the catcher to control with ordinary effort, thereby allowing a baserunner, perhaps even the batter-runner on an uncaught third strike, to advance., Jack Roosevelt "Jackie" Robinson (January 31, 1919  October 24, 1972) was an American professional baseball second baseman who became the first African American to play in Major League Baseball (MLB) in the modern era. Robinson broke the baseball color line when the Brooklyn Dodgers started him at first base on April 15, 1947. The Dodgers, by signing Robinson, heralded the end of racial segregation in professional baseball that had relegated black players to the Negro leagues since the 1880s. Robinson was inducted into the Baseball Hall of Fame in 1962., The Continental League of Professional Baseball Clubs (known as the Continental League or CL) was a proposed third major league for baseball in the United States and Canada, announced in 1959 and scheduled to begin play in the 1961 season. Unlike predecessor competitors such as the Players' League and the Federal League, it sought membership within organized baseball's existing organization and acceptance within Major League Baseball. The league disbanded in August 1960 without playing a single game as a concession by William A. Shea as part of his negotiations with Major League Baseball to expand to incorporate at least eight new teams., 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"., Racial segregation is the separation of humans into racial or other ethnic groups in daily life. It may apply to activities such as eating in a restaurant, drinking from a water fountain, using a public toilet, attending school, going to the movies, riding on a bus, or in the rental or purchase of a home or of hotel rooms. Segregation is defined by the European Commission against Racism and Intolerance as "the act by which a (natural or legal) person separates other persons on the basis of one of the enumerated grounds without an objective and reasonable justification, in conformity with the proposed definition of discrimination. As a result, the voluntary act of separating oneself from other persons on the basis of one of the enumerated grounds does not constitute segregation". According to the UN Forum on Minority Issues, "The creation and development of classes and schools providing education in minority languages should not be considered impermissible segregation, if the assignment to such classes and schools is of a voluntary nature"., The color line in American baseball, until the late 1940s, excluded, with some big exceptions in the 19th century until the line was firmly drawn, players of Black African descent from Major League Baseball and its affiliated Minor Leagues. Racial segregation in professional baseball was sometimes called a gentlemen's agreement, meaning a tacit understanding, as there was no written policy at the highest level of organized baseball, the major leagues. But a high minor league's vote in 1887 against allowing new contracts with black players within its league sent a powerful signal that eventually led to the disappearance of blacks from the sport's other minor leagues later that century, including the low minors., Roberto Enrique Clemente Walker (August 18, 1934  December 31, 1972) was a Puerto Rican professional baseball player. Clemente spent 18 Major League Baseball (MLB) seasons playing in the National League (NL) as a right fielder for the Pittsburgh Pirates. He was inducted into the National Baseball Hall of Fame in 1973, becoming the first Latin American and Caribbean player to be enshrined. His untimely death established the precedent that, as an alternative to the five-year retirement period, a player who has been deceased for at least six months is eligible for entry into the Hall of Fame., In baseball, the pitcher is the player who throws the baseball from the pitcher's mound toward the catcher to begin each play, with the goal of retiring a batter, who attempts to either make contact with the pitched ball or draw a walk. In the numbering system used to record defensive plays, the pitcher is assigned the number 1. The pitcher is often considered the most important defensive player, and as such is situated at the right end of the defensive spectrum. There are many different types of pitchers, such as the starting pitcher, relief pitcher, middle reliever, lefty specialist, setup man, and closer., 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., A tournament held in 1933 at the Chicago World's Fair spurred interest in the game. The Amateur Softball Association (ASA) of America (founded 1933) governs the game in the United States and sponsors annual sectional and World Series championships. The World Baseball Softball Confederation (WBSC) regulates rules of play in more than 110 countries, including the United States and Canada; before the WBSC was formed in 2013, the International Softball Federation filled this role. Women's fastpitch softball became a Summer Olympic sport in 1996, but it (and baseball) were dropped from the 2012 Games; they will be reinstated for the 2020 Games., A batting helmet is worn by batters in the game of baseball or softball. It is meant to protect the batter's head from errant pitches thrown by the pitcher. A batter who is "hit by pitch," due to an inadvertent wild pitch or a pitcher's purposeful attempt to hit him, may be seriously, even fatally, injured., The Federal League of Base Ball Clubs, known simply as the Federal League, was an American professional baseball league that played its first season in 1913 and operated as a "third major league", in competition with the established National and American Leagues, from 1914 to 1915., Wesley Branch Rickey ( December 20 , 1881 -- December 9 , 1965 ) was an innovative Major League Baseball ( MLB ) executive elected to the Baseball Hall of Fame in 1967 . He was perhaps best known for breaking Major League Baseball 's color barrier by signing African American player Jackie Robinson , for drafting the first Afro - Hispanic superstar , Roberto Clemente , for creating the framework for the modern minor league farm system , for encouraging the Major Leagues to add new teams through his involvement in the proposed Continental League , and for introducing the batting helmet . Rickey played in MLB for the St. Louis Browns and New York Highlanders from 1905 through 1907 . After struggling as a player , Rickey returned to college , where he learned about administration from Philip Bartelme . Returning to MLB in 1913 , Rickey embarked on a successful managing and executive career with the St. Louis Browns , the St. Louis Cardinals , Brooklyn Dodgers and Pittsburgh Pirates . The Cardinals elected him to their team Hall of Fame in 2014 . Rickey also had a career in the sport of American football , as a player for the professional Shelby Blues and as a coach at Ohio Wesleyan University and Allegheny College . His many achievements and deep Christian faith earned him the nickname `` the Mahtm . '', The Pittsburgh Pirates are an American professional baseball team based in Pittsburgh, Pennsylvania. The Pirates compete in Major League Baseball (MLB) as a member club of the National League (NL) Central division. The Pirates play their home games at PNC Park; the team previously played at Forbes Field and Three Rivers Stadium, the latter of which was named after its location near the confluence of the Allegheny, Monongahela, and Ohio Rivers. Founded on October 15, 1881 as Allegheny, the franchise has won five World Series championships. The Pirates are also often referred to as the "Bucs" or the "Buccos" (derived from buccaneer, a synonym for pirate)., Pittsburgh is a city in the Commonwealth of Pennsylvania in the United States, and is the county seat of Allegheny County. The Combined Statistical Area (CSA) population of 2,659,937 is the largest in both the Ohio Valley and Appalachia, the second-largest in Pennsylvania after Philadelphia and the 20th-largest in the U.S. Located at the confluence of the Allegheny and Monongahela rivers, which form the Ohio River, Pittsburgh is known as both "the Steel City" for its more than 300 steel-related businesses, and as the "City of Bridges" for its 446 bridges. The city features 30 skyscrapers, two inclines, a pre-revolutionary fortification and the Point State Park at the confluence of the rivers. The city developed as a vital link of the Atlantic coast and Midwest. The mineral-rich Allegheny Mountains made the area coveted by the French and British empires, Virginia, Whiskey Rebels, and Civil War raiders., Subject: branch rickey, Relation: occupation, Options: (A) baseball player (B) canada (C) game (D) hotel (E) major (F) member (G) pirate (H) relief pitcher (I) revolutionary (J) runner
