Directions below BEFORE you begin!!

The Affinity Software program works best with a laptop or desktop computer.  If you use a tablet or a cell phone and have problems please try to use a computer before contacting us.

Before registering for a Blast team you will need the following:


This is linked to your family account through Calsouth.  Any player that has ever played soccer for a Calsouth team (i.e. – PYSL, La Jolla Impact, Albion, etc) has an account already that was created on the back end by the registrar. If you do not have a Calsouth account or cannot remember your login, please contact Affinity Software by clicking the “forgot username/password” button. You just need your email address that you used when you previously registered through any Calsouth league. You can also email Patti Ghio at to reset your password.  Please include the player’s name and your contact phone. DO NOT CREATE A DUPLICATE RECORD as your child will not be rostered to a team through Affinity Software if a duplicate record is created.


Your coach or team manager should have supplied you with your team’s code.


You will not be able to complete the application if you do not have a copy of the birth certificate and a current picture ready to upload to the application
