The University of Calgary Dinos Fastball Club is one of the founding team members of the Alberta Intercollegiate Women’s Fastball Association (AIWFA). The AIWFA was established in western Canada in 2002, and consisted of five teams. Now called the Western Collegiate Fastball Association ( WCSA ), the league has eight teams, and now includes SAIT Polytechnic, the University of Saskatchewan, Briercrest College and Seminary, the University of Regina, the University of British Columbia-Okanagan, the University of Lethbridge and in 2020 the University of Victoria.

In 2008, the University of Calgary hosted the inaugural Canadian Collegiate National Championship. The University of Calgary is the only school to have attended all eleven Canadian Collegiate National Championships. The Dinos have medalled three times, most recently a Silver in 2019, matching with the 2011 team as National runner up.  The Canadian Collegiate Softball Association ( CCSA ) oversees the National Championships, setting qualification guidelines for the WCSA, the Ontario Colleges Athletic Association ( OCAA ) and the Ontario Intercollegiate Women's Fastpitch Association ( OIWFA ). 

Since the 2011 season the Dinos have undertaken most ambitious schedules, playing in over 30 games each season, including  trips into the United States, and the Dinos have raised their expectations of success. The 2014 season saw the team build on their 2013 season's successful 16 win, 1 loss regular season record, by capturing the WCSA Championship during the 2014 playoffs. Since 2010, the team has earned at least a bronze medal finish in the League Championships each year. These successes have ensured berths into the CCSA National Championships each October, and  the 12 straight appearances at Nationals for the Dinos are unmatched by any school in Canada. Dinos have seen success at the Nationals too, with a Silver Medal in 2011, and most recently in back to back years, a Bronze medal in 2018 followed by a Silver medal finish in 2019.
