completed nine innings of a game on May 2, 1917, without either giving up a hit or a run; Vaughn gave up two hits and a run in the 10th inning, losing the game to Toney, who completed the extra-inning no-hitter. MLB no-hitters Definition A no-hitter is defined by MLB: "An official no-hit game occurs when a pitcher (or pitchers) allows no hits during the entire course of a game, which consists of at least nine innings." This 1991 definition by MLB's Committee for Statistical Accuracy caused previously recognized no-hitters of fewer than nine innings or where the first hit had been allowed in extra innings to be stricken from the official record books. Games lost by the visiting team in innings but without allowing any hits do not qualify as no-hitters, as the visiting team has only pitched eight innings. Frequency MLB has recognized 318 no-hitters thrown since 1876, 23 of which were perfect games. Two no-hitters have been thrown on the same day twice: Ted Breitenstein and Jim Hughes on April 22, 1898; and Dave Stewart and Fernando Valenzuela on June 29, 1990. Nine no-hitters were thrown in the 2021 season. The previous record was eight, set in 1884. The previous modern era record (since 1901) was seven, accomplished in 1990, 1991, 2012, and 2015. The longest period between two no-hitters in the modern era is three years and 44 days, between Bobby Burke on August 8, 1931, and Paul "Daffy" Dean on September 21, 1934. There was a drought of three years and 11 months without a no-hitter after the first National League no-hitter on July 15, 1876, pitched by George Bradley. The most recent year without any no-hitters is 2005. The greatest span of games without a no-hitter in the major leagues is 6,364, between Randy Johnson's perfect game on May 18, 2004, for the Arizona Diamondbacks, and Aníbal Sánchez's no-hitter on September 6, 2006, for the Florida Marlins. The previous record was a 4,015-game streak without a no-hitter from September 30, 1984, to September 19, 1986. Individual The pitcher who holds the record for the most no-hitters is Nolan Ryan, who threw seven in his 27-year career. His first two came exactly two months apart with the California Angels: the first on May 15, 1973, and the second on July 15. He had two more with the Angels on September 28, 1974, and June 1,
