It secured a home tie in the quarter-final for Simon Mackenzie’s men, who complete their round-robin campaign with a trip to Swanston.
Title holders Royal Burgess are also on course to be at home in the last eight after overcoming a trip to Torphin Hill with an under-strength team.
“We had eight of our squad of 14 unavailable,” said Burgess team manager Richard Hughes. “However, a spirited performance saw us win 5½-2½.”
Hughes himself was called into action for his first league match in 15 years and managed to secure a half.
Performance of the night, however, came from Varun Varadharajan, who was six-under for 11 holes in beating David Morrans 9 and 7.
Liberton’s hopes of making the quarter-finals were dented as they had to settle for a 4-4 draw at Lothianburn.
And, in a game between two teams without a win this season, Prestonfield made home advantage count to beat Craigmillar Park.
