The Calgary Mixed Slo-Pitch Softball League has been operating since 1978, offering a fun and competitive brand of Slo-Pitch out of Optimist Athletic Park. The CMSL operates on three nights: Mondays (A Division), Wednesdays (B Division), and Thursdays (C Division). In a typical season, all games on your night of softball are double headers with CSUA umpires. All games are at Optimist Athletic Park. There is a 22-game schedule with potential for playoffs. The season starts in mid-May and ends in late August. Playoffs are usually held on the final weekend in August. The top eight teams in each division qualify.
