Chicago Mainliner Softball Tournament

  • Our tournament will be Saturday, September 7 starting at 9am at Majewski Park in Mt. Prospect. This is the same park we’ve played since tournament inception. 


  • Chicago Mainliner Club is planning a fun day for everyone. We will be providing box lunches for team players from a new caterer. More information on this will be provided during sign-up with the entry form. 
  • We will be playing the same as in the past:  
  • 1. co-ed teams (minimum 4 females on a team) 
  • 2. double elimination
  • 3. you can have up to 2 additional non-employee FEMALE players on your team, if they are listed under pass travelers (enrolled friends)
  • 4. NEW THIS YEAR – We will take a 30 minute break at 1pm (to ensure all players get time to rest & eat lunch) 


  • Food trucks are not allowed on park district property or street in front.  


  • There will be only 8 team slots open this year and we want to make sure returning teams have 1st chance to sign up. We will not accept entry packets early & they will be returned to sender. I have received emails from individual players who’d like to play and will forward those out to the captains in case they need players to complete their teams.  


  • See below for important dates.
  • May 16-17 – Entry Form & information will be emailed to participants
  • June 1 – Returning teams can submit Entry forms with team fee via US Mail or email (with payment to be submitted over the phone via credit card)
  • June 10 – ANY team can submit Entry forms if slots available with team fee the same as above
  • August 21 or 22 – Team Captain Zoom meeting & DRAW for team match up
  • August 31 – Final food count submitted to me for all players 
  • September 7 – Softball Tournament
