The GMCF Pickleball Mash-up is a one-of-a-kind tournament format where players register as individuals, play round robin doubles with players at a similar ability level, and continue to play as long as they place well in each subsequent round robin. The tournament is seeded by DUPR rating, with start times defined by seeding, but the tournament results will not be entered into the DUPR rating system. Players are guaranteed a minimum of 6 games, but most will play more.
