List of San Francisco Giants no-hitters  The San Francisco Giants are a Major League Baseball franchise based in San Francisco, California. They play in the National League West division. Also known in their early years as the "New York Gothams" (1883–84) and "New York Giants" (1885–1957), pitchers for the Giants have thrown 17 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", although one or more batters "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 still never had a pitcher accomplish the feat, and teams may go decades without recording one. A perfect game, a special subcategory of no-hitter, was finally thrown by Matt Cain on June 13, 2012. As defined by Major League Baseball, "in a perfect game, no batter reaches any base during the course of the game." Previously, this feat came closest on July 4, 1908 when Hooks Wiltse was hit by a pitch with two outs in the ninth and a scoreless tie. The plate umpire, Cy Rigler, claimed he should have called the previous pitch strike three, that would have ended the inning with a perfection. Wiltse would go on to retire all three in the tenth to end the game after the Giants scored a run in the top of the tenth. Amos Rusie threw the first no-hitter in Giants history on July 31, 1891; the most recent no-hitter was thrown by Chris Heston on June 9, 2015. Five left-handed pitchers have thrown no-hitters in franchise history. The other ten pitchers were right-handers, including the most recent no-hitter author, Heston. Tim Lincecum and Hall of Famer Christy Mathewson are the only pitchers to throw more than one no-hitter in a Giants uniform. Ten no-hitters were thrown at home and seven on the road. The Giants threw one in April, two in May, five in June, five in July, one in August, and three in September.
