St Patrick's Athletic have won the first Dublin derby of the season, thanks to three headed goals from Mark Timlin, Christy Fagan and Billy Dennehy against 10-man Bohemians at Richmond Park.
It is back-to-back wins for the EA Sports Cup champions after they secured their first win of the season at Longford on Friday.
And it was a bright start from Liam Buckley's side as St Pat's stunned Bohemians with two goals inside the first 15 minutes at the Inchicore venue.
There were just five minutes on the clock when Billy Dennehy found Ian Berminham in space and the left-back's cross found the head of Timlin for the opening goal of the game.
The left flank provided all sorts of problems for Bohs, as Dennehy and Bermingham combined time and time again to carve open several chances for the hosts in the first-half.
The second goal of the game was not too long in coming, as Dennehy's cross was met by the head of Fagan for the striker to net his third in as many games. Pat's were now 2-0 up with less than quarter of an hour gone.
Two nearly became three when Fagan found himself through on goal after Roberto Lopes fluffed his clearance, but a tame effort from the in-form striker was saved by Dean Delany.
Saints were brimming with confidence and despite having an influx of new faces in the close season, they were passing and moving the ball with purpose.
Although the game was the third match in 11 days for both sides, there was a good intensity to the early part of the game.
There were also some full-blooded tackles for the Inchicore crowd to enjoy, resulting in Paddy Kavanagh and Ismahil Akinade seeing yellow.
Pat's continued to keep the pressure on the Bohemians defence, denying the visitors any clear openings in the first half.
Brendan Clarke in the St Pat's goal was hardly troubled and dealt with a shot from Kurtis Byrne and a free-kick from Mark Quigley with relative ease.
It was an unhappy return to Richmond Park for Quigley, despite playing in a free role he struggled to breach his former club's defence.
Keith Long's men dominated the start of the second-half but still failed to sting the gloves of Clarke with their most likely route of a goal coming from a set-piece.
Pat's found themselves dropping deeper and deeper but the hosts were always comfortable.
Any hope of Bohs getting back into the game evaporated when striker Akinade was sent off for a second yellow for a late challenge on Shane McEleney.
Pat's nearly extended their lead when David Crawley whipped in a teasing cross but there was nobody on the end on it after more good play from Dennehy.
As the game was coming to an end Dennehy got a goal that his performance deserved with the third header of the night.
Only one place and five points separated these teams in the table last season, but based on this encounter, you would not expect the same this season.
Up next for Pat's is another meeting against Dublin rivals, when they travel to Shamrock Rovers on Friday night, while Bohemians host newly promoted Wexford Youths.
