Prior to this victory Misterton had lost 10 in a row and looked like wooden spoon candidates. They have climbed to tenth and their fate now rests on whether they can reproduce this form and pull clear of bottom place.
The result doesn't make much difference to Marshalls A except to make overtaking Beckingham seem unlikely, but their Kelsey Cup position is secure.
Melrose SSC were given a hard time on three rinks by visitors Marshalls Sports but the home rink of Jack Brown, Tony Bainbridge and Graham Cowan won 30-9 to settle the aggregate to give Melrose an 8-2 (90-54) win.
Scotter 1 had an easy time at Marton GB, winning all four rinks comfortably 10-0 (103-41) to edge nearer to Melrose, and Beckingham visited Scotter 2 and came away 10-0 (103-48) winners to keep in touch.
Cottam 2100 enhanced their Kelsey Cup qualifying hopes with a very good 8-2 (83-63) win at Lincoln Co-op with two rinks winning by double figures.
Owston Ferry had one of those matches against visitors Rose A where none of the rinks were close but the aggregate was. However, three home rinks won to produce an 8-2 (80-71) result for Ferry.
The four Millennium Trophy matches produced one surprise - a victory for Misterton over Lincoln Co-op, showing that their win over Marshalls A was no fluke.
