Since the foundation of the Pacific Coast League (PCL) in 1903, its pitchers have thrown 169 no-hitters, which include 10 perfect games. Of these no-hitters, 108 were pitched in games that lasted at least the full 9 innings, while 61 were pitched in games shortened due to weather or that were played in doubleheaders, which are typically 7 innings. Only 3 of the league's 10 perfect games were tossed in full 9-inning games. Eleven no-hitters, including one perfect game, were combined—thrown by two or more pitchers on the same team.
