Darren Lavery's eight goal of the season confirmed Berwick's 3-1 win against 10-man Cutler FC.
Kenny O'Brien put the home side ahead after 17 minutes when he headed in Lee Currie's precise cross from six yards.
Scott Dalziel coolly slotted away just five minutes after the break to double his side's lead over the Scottish Junior Football North Premier League outfit.
Cutler were down to 10 with nine minutes remaining after Jamie McAllister received a second yellow but moments later, they had a route back into the game after Scott McArthur was fouled in the area.
Allan Youngson powered the penalty home but their joy was short lived as Lavery restored the two-goal cushion with five minutes remaining when he curled into the bottom corner.
