From SSUSA site:
MESQUITE CHANGE OF VENUE • SSUSA was advised early Friday that the Hunter Park and Pioneer Park softball complexes in Mesquite will NOT be available for use during the upcoming Western National's ... This COVID-closure is effective immediately and there is no current targeted expiration date ... Arrangements are nearly concluded for expanded use of the previously listed St. George facilities and lease acquisition of other softball complexes in the area ... In addition to the divisions moving from Mesquite, certain other divisions of play will also relocate to meet the games demand geometry of the changes ... The tentative Master Plan has been redone to incorporate these changes and will be released shortly after official civic arrangements are confirmed, possibly as early as Monday ... Thank you!
