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", though 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".[3] 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.[4]
No perfect games, a special subcategory of no-hitter, have been thrown in Pirates history.[5] However on May 26, 1959, Harvey Haddix threw a 12-inning perfection until the fielding error by Don Hoak ended his perfection and eventually lost his no-hit bid and a game.[6] As defined by Major League Baseball, "in a perfect game, no batter reaches any base during the course of the game."[3]
History
Nick Maddox threw the first no-hitter in Pirates history on September 20, 1907; the most recent no-hitter was jointly thrown by Francisco Córdova and Ricardo Rincón on July 12, 1997.[5] Two left-handed starting pitchers have thrown no-hitters in franchise history while four were by right-handers. Three no-hitters were thrown at home and three on the road. They threw one in May, one in June, one in July, one in August, and two in September. The longest interval between no-hitters was between the games pitched by Maddox and Cliff Chambers, encompassing 43 years, 7 months, and 16 days from September 20, 1907 till May 6, 1951. Conversely, the shortest interval between no-hitters was between the games pitched by Moose and Dock Ellis, encompassing merely 8 months and 23 days from September 20, 1969 till June 12, 1970.[5] They no-hit the Los Angeles Dodgers (formerly "Brooklyn Superbas") the most, which occurred twice, which were no-hit by Maddox in 1907 and Candelaria in 1976. There is one no-hitter which the team allowed at least a run, thrown by Maddox in 1907. There is one no-hitter which had a dramatic finish: Mark Smith hit a game winning three-run home run in the bottom of the tenth inning on July 12, 1997. The most baserunners allowed in a no-hitter was by Ellis (in 1970), who allowed nine. Of the 6 no-hitters, three have been won by a score of 3–0, more common than any other results. The largest margin of victory in a no-hitter was a 3–0 wins by Cliff Chambers in 1951, Bob Moose in 1969, and a combined no-hitter by Córdova and Rincón in 1997. The smallest margin of victory was a 2–1 win by Maddox in 1907. The Pirates have the longest active complete game no-hitter drought in MLB (while the Indians have the longest active no-hitter drought overall).
Umpires and managers
The umpire is an integral part of any no-hitter. The task of the umpire in a baseball game is to make any decision "which involves judgment, such as, but not limited to, whether a batted ball is fair or foul, whether a pitch is a strike or a ball, or whether a runner is safe or out... [the umpire's judgment on such matters] is final."[7] Part of the duties of the umpire making calls at home plate includes defining the strike zone, which "is defined as that area over homeplate(sic) the upper limit of which is a horizontal line at the midpoint between the top of the shoulders and the top of the uniform pants, and the lower level is a line at the hollow beneath the kneecap."[7] These calls define every baseball game and are therefore integral to the completion of any no-hitter.[8] A different umpire presided over each of the Pirates' six no-hitters.
The manager is another integral part of any no-hitter. The tasks of the manager is to determine the starting rotation as well as batting order and defensive lineup every game. Managers choosing the right pitcher and right defensive lineup at a right game at a right place at a right time would contribute to a no-hitter.[citation needed] Five different managers have led to the Pirates' six no-hitters.
