CMSL League Info

The Calgary Mixed Slo-Pitch League has been operating since 1978, offering a fun and competitive brand of Slo-Pitch out of Optimist Athletic Park

The CMSL operates on 3 nights: Mondays (A Division), Wednesdays (B Division) and Thursdays (C Division).

Playoffs will be played the week of August 19, culminating on Saturday August 24.  The top 8 teams in each Division qualify.
