The 43nd consecutive season of CSBL summer baseball began on Wednesday when the Beecher Muskies defeated the Lake County Corndogs by a score of 10 to 3, and the Addison Braves defeated the Oswego Cats by a score of 4-3.  The victory for the Braves was the 1000th career victory for manager Larry Kurkowski. The team honored their coach with a commemorative plaque. 

This season, each of the CSBL teams will play five games against one another. Each team will also play two games against the Crown Point Corn Dogs and Calumet Beavers for a total of 29 games.

After completion of the regular season, the CSBL will host the NABF Major Division World Series.
