A Schedule Request Pack can be added to your team balance before the schedule has been made. There is a $80 pack for multiple dates, or a $20 if you just need a single date. A Schedule Request consists of the time, date, or location of your games…Make sure you’re specific on your request!

A full season request where the majority (but not all) of your requests have been granted will be charged the entire full season request fee.

Any requests sent in after a schedule has been posted will be considered a game change and will be $50 for each change that we are able to accommodate.

We will do our best to accommodate requests whenever possible, and are able to accommodate them about 95% of the time. However, schedule requests are never guaranteed.
