Michael Tidser bagged a second-half brace as Morton eased to a 3-0 replay victory over Albion to secure a fourth-round trip to Turriff United in the Scottish Cup.
The sides played out a 1-1 draw in the original tie and Albion's David Crawford drew a sharp save from Morton goalkeeper Derek Gaston in the 19th minute.
David Graham should have put the hosts ahead when he volleyed wide on the stroke of half-time, but a dominant second-half display meant he would not rue his profligacy.
Graham was the provider in the 51st minute, crossing from the left for Martin Hardie to plant a header high beyond Matthew McGinley.
Barely a minute later, Tidser converted Fouad Bachirou's pass to leave the visitors reeling.
And Tidser completed Albion's misery 19 minutes from time when David O'Brien teed him up to crash home emphatically from the edge of the box.
