Ed McGinty was Sligo Rovers' hero as the Bit O’Red somehow emerged from a second-half Shamrock Rovers onslaught, to take a point from Tallaght.
McGinty pulled off several impressive stops in each half to repeatedly deny the home side.
The Hoops even had goalkeeper Alan Mannus in the Sligo box for two late corners, such was the Dubliner’s domination of this game.
Sligo had only ever beaten their opponents twice on their own patch since Tallaght’s inception ten years ago. That record never looked likely to change.
Jack Byrne, instrumental in Sligo’s last visit to Dublin 24, showed form once more and went close early on. His cheeky turn past his marker allowed him time and space to launch an effort at goal from the edge of the area.
But the in-form McGinty did enough to keep the Irish international at bay. The Bit O’Red were sloppy in their distribution from the back at times and almost paid for this on 19 minutes.
A loose ball from deep was set upon by Dylan Watts whose initial effort was blocked. Possession falling to Sean Kavanagh who steadied himself before blasting over from ten yards.
Debutant Graham Cummins should have had the Hoops ahead three minutes from the break. Unmarked and with Sligo’s centre halves and sixes and sevens, the former Cork City man could only crack his free header from a Greg Bolger cross straight on to McGinty’s crossbar.
The Scot continued to keep the westerners in this. Twice denying Kavanagh before the break with a couple of fine stops. McGinty was at it again moments after the re-start as he got a finger-tip to Byrne’s belter from distance.
While the same man was alert to come and meet Cummins to block down the striker’s go at goal just before the hour.
It remained one-way traffic and McGinty was again the hero as he spread himself to divert Cummins’ next effort away. Substitute Dan Carr could only drag his effort from the angle wide of the target on 65 with Stephen Bradley’s charges remaining frustrated.
McGinty then had to push Watts’ cross on to his own crossbar with fifteen to go as the Dubliners continued to smother Sligo with pressure. Cummins, Carr and Gary O’Neill all had chances to convert as news of Derry’s late leveller against Dundalk filtered through.
However, Sligo somehow held out for a valuable point on the road.
