Two goals in the last five minutes helped Derry keep the pressure on Sligo with a 2-1 win over Limerick.
Limerick drew first blood at the Brandywell when Shane Tracy's corner was met by Stephen Folan's header, which flew past Ger Doherty.
It took until the 86th minute for Derry to equalise as Mark Griffin capitalised on a scramble in the box. Two minutes later they were in front when Rory Patterson deflected home a Barry McNamee effort, and that's how it stayed.
Bohemians came from behind twice to claim a 2-2 draw with Drogheda United at Hunky Dory Park.
Drogheda got off to the perfect start as they earned a corner direct from the kick-off, it was taken short to David Cassidy who found Michael Daly and his header flew past the hapless Dean Delaney.
Bohs scored a controversial equaliser seven minutes before the break when Dwayne Wilson appeared to control the ball with his hand before firing to the net.
Three minutes later the Drogs reclaimed the lead through Paul O'Connor's tap-in after his initial header was cleared off the line. Bohs equalised for a second time after the break when Andy Mulligan embarked on a great run and his shot was parried into the path of Ryan McEvoy, who couldn't miss, and they held on for a point.
