Expos pitcher Pascual Pérez threw a five-inning rain-shortened no-hitter against the Phillies on September 24, 1988. It was the first no-hitter in Veterans Stadium history. Perez allowed one walk, and another Phillies baserunner reached on an error. Umpire Harry Wendelstedt waved off the game after a 90-minute rain delay after the game was stopped by a steady rain with one out in the top of the sixth. However, due to a statistical rule change in 1991, no-hitters must last at least nine innings to count. As a result of the retroactive application of the new rule, this game and thirty-five others are no longer considered no-hitters.
