Mad Batters came together in the spring of 1986 due to the folding of another, much larger league. Many of the teams, which were left with no place to play, decided to form their own volunteer non-profit group with a mandate to provide the inherent fun in Co-ed slo-pitch mixed with good competition. The first couple of years revolved around much trial and error until affiliation with Softball Calgary came to be. This brought many benefits such as good diamonds, tournaments like the City championships, no cost insurance and bulk supplies, etc. In 1999 we also became associated with the National Softball Association and it's Umpires.

Our league plays at the Deerfoot Diamonds off 16th Ave N.E. beginning the first week of May ending the last week of July. There are three divisions of 8 teams each playing doubleheaders once a week on either Monday, Tuesday or Wednesday nights, excluding holidays and most of Stampede week. Rainouts are sometimes made up on Thursday and Friday nights. Four teams from the league will be rewarded with a trip to the City Championships in either the D, or E divisions.

There is a League Tournament at Okotoks at "On Deck",  in June which is included in the team fees. Entry is also open for few outside spots. Great fun and prizes.
