Bohemians all but ended Shamrock Rovers’ slim Premier Division title hopes at Dalymount Park on Sunday morning.
Rovers now trail leaders Shelbourne by 12 points with just nine games left to play, although the Hoops do have a game in hand on the Reds.
But it could have been a perfect day for Stephen Bradley’s side who took the lead after just 15 minutes through Neil Farrugia.
Bohs, however, awoke from their slumber and levelled soon after with Ross Tierney netting after Lee Grace was caught napping when trying to deal with a Dawson Devoy ball.
Darragh Burns then went close for Rovers before the break before inexplicably missing the target with the goal gaping.
The game turned in the second half when Grace was given his marching orders after picking up two yellow cards in 14 minutes.
And striker Filip Piszczek eventually won it for Bohs late on when heading in a Jordan Flores cross.
