East Lothian are the team with momentum and killer instinct these days and they took no prisoners with a powerful display made gloriously comprehensive by wins on all four rinks.
"It is a major bonus for us that we have gone top of the table on shot margin with the defeat of Midlothian at West Lothian," said team captain Mal Higgenbotham who regained his place in the team after the late withdrawal of Billy Mellors.
Six defeats in a row leaves Bainfield anchored at the foot of the table with nearest rivals West Lothian four points better off, while Aberdeen and Auchinleck lie six ahead.
Paul Foster, the world No.?1, was spoken of as the 'man of the match' after producing an awesome performance to skip Higgenbotham, Steven Morgan and Andrew Jeffrey to a 27-13 win over Craig Paterson, Graeme McIntosh, Jamie Aitken and Robert Marshall.
Graham Robertson returned to winning form in great style as he skipped Mark Johnston, David Oliver and Willie Wood to a commanding 21-10 triumph over Martyn Dickson, Scott Patterson, Alan Brown and Jamie Gracie.
Derek Oliver celebrated his fifth win in a row as he skipped Colin Cook, Dougie Berwick and Jamie Higgins to a 19-16 success over Chris Downie, Stephen Pringle, Colin Hutchison and Gavin Smith.
Alex Marshall and his rink of John Stevenson, Stevie Thomson and Scott Kennedy completed the clean sweep as they survived a late assault to score a 22-20 win over Craig Moss, Graham Pringle, Chris Wilson and Paul O'Donnell.
Meanwhile, Balbardie continued to frustrate their support with another disappointing result that saw them suffer an 82-62 defeat from Division 1B leaders Alloa at Bathgate.
Balbardie had to win to keep their dream of promotion to the Premier League alive but, instead, it is relegation that becomes an issue as they share a crowded bottom rung with Stirling and Portobello.
