The 1972 Major League Baseball strike forced the cancellation of the first seven games (thirteen game-days) of the season. The 1981 Major League Baseball strike caused the season to split into two halves. This caused Major League Baseball to hold the Divisional Series so that the first- and second-half champions could play each other to determine playoff spots for the NLCS and World Series. As such, the Expos finished one-half game ahead of the second-place St. Louis Cardinals in the second half of the 1981 season. The 1994–95 Major League Baseball strike  ended the season on August 11, as well as cancelling the entire postseason. While Montreal was leading by six games ahead of the second-place Atlanta Braves at the beginning of the strike, no team was officially awarded any division titles.
