Brendan Clarke salvaged a point for second in the table St. Patrick's Athletic with a late penalty save against Cork City at Richmond Park.
Liam Buckley's Dubliners may feel they had the better chances throughout the game, but it was Cork's Tadhg Purcell who was left kicking himself at the finish for not winning it for City from a 78th minute penalty.
Saints' defender Kenny Browne had fouled Purcell to concede the spot kick. His keeper Clarke then saved his blushes when stopping Purcell's poor penalty with his feet.
The 0-0 draw means St. Pat's missed the chance to put pressure on leaders Sligo Rovers, who remain three points clear at the top, before they play Shamrock Rovers on Saturday.
Drogheda United's slack run continued as they had to settle for a 1-1 draw with Bohemians at Dalymount Park. Mick Cooke's side, so impressive earlier in the season, have now won just once in five games and travel to champions Shamrock Rovers next.
Ryan McEvoy scored for the third time in four games when volleying Bohs in front on 38 minutes.
But Drogheda levelled two minutes later when their captain Alan McNally drilled home after Bohs failed to clear Eric Foley's corner.
Jason Byrne scored twice, both from the penalty spot, to bring his tally of goals for the season to eight as Bray Wanderers won 2-0 at Dundalk.
Byrne won the first spot kick himself on 40 minutes and confidently drove it past Peter Cherrie.
The second came on 73 minutes after Kieran Waters had been fouled in the area and Byrne once again beat Cherrie from 12 yards.
Shelbourne also enjoyed a 2-0 away win at UCD, despite playing much of the game with ten men.
The match burst into action from the first whistle with Shels taking the lead after just 20 seconds; Philip Gorman getting the final touch to turn home a cross from Paddy Kavanagh.
But 12 minutes later Shels had left-back Sean Byrne sent off when he was shown a straight red card by referee Alan Kelly for a challenge on Mark Langtry.
UCD struggled to make their numerical advantage pay and Shels snatched a second goal through skipper David Cassidy on 65 minutes after Kavanagh broke away on a counterattack to cross.
