Highlights

First Pearson Cup

The Pearson Cup was an annual mid-season exhibition between former Canadian rivals, the Toronto Blue Jays and the Expos. Named after former Prime Minister Lester B. Pearson, it was originally created to raise money for minor league baseball in Canada. In later years, it was incorporated into the interleague baseball schedule. The series began in 1978, and Canadian Bill Atkinson was the winning pitcher and scored the winning run for the Expos in the first-ever Pearson Cup game at the Olympic Stadium on June 29.
