Bohemians 1 Waterford United 0
Darren Mansaram celebrated his 23rd birthday with one of the cheekiest goals of the season to move Bohs back up to third in the table.
Mansaram had just shown great feet to turn a defender twice and shoot against a post before giving Bohs the lead on 45 minutes.
Des Byrne whipped over a low cross from the left and Mansaram, with his back to goal, cleverly leaned back into defender Alan Keel and as he fell flicked the ball into the bottom corner of the net.
Bohs had a let off on 74 minutes when Robert Brosnan's shot was cleared off the line by Owen Heary before Daryl Kavanagh headed narrowly wide after the resultant corner wasn't cleared.
But Fergal Harkin might have increased Bohs winning margin but for two top saves in stoppage time from Delaney.
