Strikes from Jaydn Burnett and Liam Old were enough to see Riverside into the Last 16 of the Scottish Cup. The Dundee scored twice in the second half to see off Portobello CFA.
Both these sides have been in fine form domestically this season and it was Riverside that looked to seize the initiative early on in the match as Jamie Richardson went close to opening the scoring twice early on.
The first opportunity saw the forward denied by Rory Comerford before he glanced a header wide from a matter of yards out shortly after.
Portobello could only clear Arran Taylor’s free kick as far as Jaydn Burnett, who tested Comerford with a controlled volley from the edge of the box.
Riverside looked to have finally beaten the inform Comerford when Richardson slipped the ball through to Odin Chalmers, but he saw his first-time strike come crashing off the woodwork.
Portobello had offered little in an attacking sense in the opening 35 minutes and nearly fell behind with the final touch of the half when Aidan McDougall headed wide from a corner.
