basically a "sweeper" is a mini-tournament, either held by itself, some centers run Saturday night Sweepers, or in conjunction with a larger format...at the SrHighRoller,..they run 2-3 game sweepers before-between squads-and evenings to give bowlers a chance to "play and tune their games" while waiting for their Roller qualifying squads,..sweepers run brackets and high pots, and usually are only one squad with an immediate pay off..
