Dan Carr scored midway through the first half as Shamrock Rovers earned easy passage to the second round of the FAI Cup with a 1-0 win over Finn Harps in Tallaght.
The Hoops were dominant throughout and could have won more comfortably had Harps' shot-stopper Mark McGinley not been in such fine form.
Harps set their stall out early with a flat back five against a Rovers said featuring a second debut for Graham Burke, who has returned on a year-long loan from Preston North End.
Burke had two chances to open the scoring early on but he side-footed wide following excellent work by Ethan Boyle before hitting the side netting from a good position.
Ronan Finn had rattled the woodwork inside three minutes when Sean Kavanagh’s cross was deflected into his path by Carr, and the skipper was unlucky to see his header hit the post.
Harps created little in either half but they had a half-chance early on when Rovers failed to clear a corner, but Raff Cretaro dragged his shot wide.
Rovers got the reward their early dominance demanded when Carr floated home a finish from a lovely Finn pass, and they should have pushed on from there.
McGinley denied Finn a second three minutes later following a quick Jack Byrne free kick and got down again to deny the captain on the cusp of half time.
The second half was comparatively tame, though Cretato and Harry Ascroft did have shots blocked before Nathan Boyle saw their best chance spurned by Alan Mannus.
Sub Aaron Greene should have sealed the win as he had two one-on-ones inside a minute but his first effort was saved before he blazed over, however it wasn’t to matter in the end.
