Debutants see Dundee through
New signings Simon Ferry, Greg Stewart and Luka Tankulic got off the mark on their debuts as Dundee sank Peterhead 4-0.
Ferry, the summer arrival from Portsmouth, opened his account in the 22nd minute when he prodded a loose ball in from close range.
Former Cowdenbeath striker Stewart got in on the act on the stroke of half-time when he drove Kevin Thomson's pass into the bottom corner.
Rory McAllister could have pulled one back for League One Peterhead with 20 minutes remaining but the midfielder blazed his shot over the crossbar.
Peter MacDonald headed in number three and ex-Wolfsburg forward Tankulic struck the fourth with eight minutes remaining.
