Burndennett are the early pacesetters in the Championship, making it four wins on the bounce, closely followed by Ardmore after both teams won their rearranged games on Sunday.
Salman Ahmed's fine start to the campaign continued as he top scored hitting 4 sixes and fours in his 71, helping Burndennett to post 232 for 9 in a rain-interrupted innings at home to St Johnston.
He was well supported by Ross McCay (30) and by experienced duo Stephen McCay and Mark Roulston, who both scored 37.
Ian MacBeth took three wickets, while there were two apiece for David Anthony, Scott Devenney and Nathan Cole.
Further rain saw St Johnston needing 227 from 41 overs - DLS not really in their favour this time.
Nathan Cole hit 61, David Anthony 43 and Michael Rankin 39 in a battling effort, but they fell 18 runs short on 209 for 8.
Ardmore stay second after a routine 8-wicket win at home to Bonds Glen.
The Bee Gees managed to score just 84, with Raymond Curry hitting 40.
Caolan Young took three wickets, while there were two apiece for George and Lee Brolly.
Ardmore skipper Peter Harrigan's half century eased the Bleachgreen side to victory.
There was a consolation for Bonds Glen though, as they won a bowl-out 2-1 after the T20 game between the teams had been washed out on Friday.
