<P> The Boston Red Sox are a Major League Baseball franchise based in Boston, Massachusetts, also known in their early years as the "Boston Americans" (1901--07). They play in the American League East division . Pitchers for the Red Sox have thrown 18 no - hitters in franchise history . </P> <P> A no - hitter is officially recognized by Major League Baseball "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, the San Diego Padres, has never had a pitcher accomplish the feat . The New York Mets' first no - hitter (pitched by Johan Santana) came on June 1, 2012, in the team's 8,021 st game and 51st season . </P> <P> One perfect game, a special subcategory of no - hitter, has been pitched in Red Sox history . As defined by Major League Baseball, "in a perfect game, no batter reaches any base during the course of the game ." Every opposing batter is retired . This feat was achieved by Cy Young in 1904 . Young's perfect game, pitched on May 5, 1904, also was the first no - hitter in Red Sox history; the most recent Red Sox no - hitter was thrown by Jon Lester on May 19, 2008 . </P> <P> Two pitchers have thrown more than one no - hitter in a Red Sox uniform, Hall of Famer Cy Young and Dutch Leonard . Thirteen of the Red Sox no - hitters were thrown at home (the first four at the Huntington Avenue Grounds and the other nine at Fenway Park) and five on the road . Two were thrown in April, two in May, five in June, two in July, three in August, and four in September . The longest interval between Red Sox no - hitters was 35 years, 6 months, and 18 days, between the games pitched by Dave Morehead, on September 16, 1965 and Hideo Nomo, on April 4, 2001 . The shortest interval between Red Sox no - hitters was merely 1 month and 6 days, between the games pitched by Earl Wilson on June 26, 1962 and Bill Monbouquette on August 1, 1962 . </P>
