context: Title: List of Detroit Tigers no-hitters
  Passage: The Detroit Tigers are a Major League Baseball franchise based in Detroit, Michigan.  They play in the American League Central division.  Pitchers for the Tigers have thrown seven no-hitters in franchise history.  A no-hitter is officially recognized by Major League Baseball only "when a pitcher (or pitchers) allows no hits during the entire course of a game, which consists of at least nine innings.  In a no-hit game, a batter may reach base via a walk, an error, a hit by pitch, a passed ball or wild pitch on strike three, or catcher's interference."  No-hitters of less than nine complete innings were previously recognized by the league as official; however, several rule alterations in 1991 changed the rule to its current form.  A no-hitter is common enough that only one team in Major League Baseball has never had a pitcher accomplish the feat.  A perfect game, a special subcategory of no-hitter, has yet to be thrown in Tigers history.  As defined by Major League Baseball, "in a perfect game, no batter reaches any base during the course of the game."  This feat came closest on June 2, 2010 when Armando Galarraga lost his perfect game bid against the Cleveland Indians with two outs in the ninth due to the incorrect call made by a first base umpire Jim Joyce.  But there are two other times when the Tigers perfect game bids were lost with two outs in the ninth, one in 1932 and the other in 1983.  The Tigers lead all franchises with three perfect game bids lost with two outs in the ninth.
  Title: 2011 Major League Baseball season
  Passage: The 2011 Major League Baseball season began on Thursday, March 31, and ended on Wednesday, September 28.  This marked the first time a season began on a Thursday since 1976, and the first time a regular season ended on a Wednesday since 1990.  The 82nd edition of the Major League Baseball All-Star Game was played at Chase Field in Phoenix, Arizona, on July 12 with the National League defeating the American League for the second straight year, by a score of 5–1.  As has been the case since 2003, the league winning that game has home field advantage in the World Series.  Accordingly, the 2011 World Series began on October 19, and ended on October 28, with the St. Louis Cardinals winning in seven games over the Texas Rangers.
  Title: 2011 Major League Baseball Home Run Derby
  Passage: The 2011 Major League Baseball Home Run Derby (known through sponsorship as the State Farm Home Run Derby) was a home run hitting contest in Major League Baseball (MLB) between four batters each from the National League and American League.

  Title: List of Oakland Athletics no-hitters
  Passage: The Oakland Athletics are a Major League Baseball franchise based in Oakland, California.  They play in the American League West division.  Also known in their early years as the “Philadelphia Athletics” (1901–54) and “Kansas City Athletics” (1954–67), pitchers for the Athletics have thrown eleven no-hitters in franchise history, five during the Philadelphia years and six after the move to Oakland but none during the Kansas City era.  A no-hitter is officially recognized by Major League Baseball only “when a pitcher (or pitchers) retires each batter on the opposing team during the entire course of a game, which consists of at least nine innings.”  No-hitters of less than nine complete innings were previously recognized by the league as official; however, several rule alterations in 1991 changed the rule to its current form.  A no-hitter is rare enough that one team in Major League Baseball has never had a pitcher accomplish the feat.  Two perfect games, a special subcategory of no-hitter, have been pitched in Athletics history.  As defined by Major League Baseball, “in a perfect game, no batter reaches any base during the course of the game.”  These feats were achieved by Catfish Hunter in 1968, which was the first perfect game in American League history since 1922, and Dallas Braden in 2010, which was the second perfect game in the majors – both against the same team – in ten months.

Only 16 months after Arizona was granted a major league baseball franchise, the first farm club — the Lethbridge Black Diamonds — took the field.

  Title: List of Chicago White Sox no-hitters
  Passage: The Chicago White Sox are a Major League Baseball franchise based in Chicago.  They play in the American League Central division.  Pitchers for the White Sox have thrown eighteen no-hitters in franchise history.  A no-hitter is officially recognized by Major League Baseball only “when a pitcher (or pitchers) allows no hits during the entire course of a game, which consists of at least nine innings.  In a no-hit game, a batter may reach base via a walk, an error, a hit by pitch, a passed ball or wild pitch on strike three, or catcher’s interference.”  No-hitters of less than nine complete innings were previously recognized by the league as official; however, several rule alterations in 1991 changed the rule to its current form.  A no-hitter is rare enough that one team in Major League Baseball has never had a pitcher accomplish the feat.  Three perfect games, a special subcategory of no-hitter, have been pitched in White Sox history, which equals the New York Yankees for the most perfect games pitched by any MLB franchise.  As defined by Major League Baseball, “in a perfect game, no batter reaches any base during the course of the game.”  These feats were achieved by Charlie Robertson in 1922, which was the first perfect game on the road in MLB history, Mark Buehrle in 2009, and Philip Humber in 2012.
