The Invite list for the 2013 PDGA Pro World Disc Golf Championships in Crown Point, Indiana is posted on the PDGA Worlds page. Players earning invites in multiple divisions are marked as such. Invite packets will be emailed to invitees on April 5th. Invite packets will be sent via USPS only to those invitees without an email address on record. During the first tier of registration starting on April 19th, invitees may only register for a division they were invited for. If they wish to register in a division they were not invited for, they may do so on May 24th when the second tier of registration starts. Non-invited Pro players may register on June 21 when the third tier of registration opens to all Professional Class PDGA members. If room still exists on July 12, registration will open to Amateur PDGA members meeting minimum ratings requirements.
