Ten-man Montrose recorded a well-deserved CIS Insurance Cup first-round victory at Stair Park.
Montrose opened the scoring on 17 minutes when Jay Stein picked up a clearance from Scott Black and lobbed the stranded keeper from 35 yards.
Captain Keith Gibson doubled their lead after 34 minutes following a scramble in the Stranraer goalmouth.
Pat Keogh scored with a header but the home side could not take advantage of Stephen Thompson's late red card.
