Jean Campbell started playing in softball tournaments for Warren where she was coached by her father, Conrad Dack, and Alex Stewart. At age 16, she was invited to play junior ball in Winnipeg for Elmwood Pats and took advantage of this opportunity as there were no organized leagues in her area. In 1957 she was named the most valuable player in the Greater Winnipeg Junior Girls Softball League and a member of the all-star team. While still junior age, the diminutive pitcher moved to senior "A" ranks the next season with West Kildonan Tigerettes and led the team to the final against the defending Western Canadian champion CUAC Blues. One of the youngest players in the league, she won the MVP trophy. After moving to Teulon in 1961 and having three children, Campbell began playing again in 1973 and helped Teulon Cougarettes to the Winnipeg and District League "C" Division championship
