The Expos were tied with the division rival Philadelphia Phillies in the standings entering the final weekend of the 1980 season with a three game series set between the two clubs at Olympic Stadium.
On October 4, with the Phillies holding a one-game lead in the standings, and with the score tied at four heading to the tenth, Mike Schmidt hit a blast deep into the seats in left field to give the Phillies a 6–4 lead and ultimate win to clinch the National League East.
In 1980, the Expos held spring training at City Island Ball Park in Daytona Beach, Florida, for the final time.
