Five second-half goals saw St Patrick's Athletic to victory over a dogged Inchicore Athletic side in a first-round FAI Cup derby at Richmond Park.

Darragh Markey, Jake Keegan (2), Conan Byrne and Simon Madden all scored following Leon Fahy-Byrne's red card early in the second half.

It was a scoreline that flattered the Saints – who were nominally the away team on home turf – despite their having never looked in danger of suffering an upset. 

The Saints dominated from the first whistle and could have led within a minute when Dean Clarke fizzed a ball across the six-yard box, but no player in blue could get a touch.

Killian Brennan went close with a free kick that just about evaded the top corner before his brother Ryan was unfortunate to see his header from Simon Madden's cross strike the bar.

Markey bundled the rebound wide in what would be a familiar sight for the Saints support in the first half.

Ryan Brennan had an even better chance to put his side ahead when he drifted free to meet Kevin Toner's cross, but a slack effort with the outside of his boot was saved by Patrick Reilly.

Markey thought he'd given his side the lead soon after when he poked the ball goalwards, but defender Derek Roche stuck out a leg to ensure the Inchicore net remained unspoiled.

Madden missed a glorious chance as he fired over from close range, before setting up Ian Turner for a header that once again flashed back off the crossbar.

Inchicore full-back Leon Fahy-Byrne was booked for a foul on Madden midway through the first half, and it was to prove pivotal as the youngster saw red within a minute of the restart.

Fahy-Byrne chopped down Dean Clarke, leaving referee Ben Connolly no option but to produce a second yellow, and a difficult task suddenly became an impossible one.

It took the Saints just ten second-half minutes to finally break the deadlock, as Markey exchanged passes with Ian Turner before sending the ball nestling in the corner.

Reilly pulled off a fantastic fingertip save to prevent Ian Bermingham doubling the lead a minute later, acrobatically tipping the captain's goalbound header over the bar.

The insurance goal finally arrived 15 minutes from time as substitute Jake Keegan's shot squirmed under the body of Reilly, an unfortunate error for the otherwise outstanding keeper.

Keegan won a penalty shortly when he went down underr Mark Donohue's challenge, though contact looked minimal, and Conan Byrne came on to score with his first touch.

The Canadian struck grabbed his second with a smart finish past the outrushing Reilly, before Madden added the pick of the night's goals with a well-struck finish from a tight angle.

Inchicore Athletic: P Reilly; S Plunkett, M Donohue, D Roche, L Fahy-Byrne; D Howe (K Malone 58), D Power, J Cronin (C O'Rourke 79), C Bolton, D Geraghty; S Kinch (S Fay 21).

St Patrick's Athletic: B Clarke; S Madden, L Desmond, K Toner, I Bermingham; K Brennan, J Lennon, D Markey; R Brennan (C Clifford 62), D Clarke (J Keegan 62), I Turner (C Byrne 80).

Referee: Ben Connolly.

Elsewhere, Bohemians had a facile 7-0 win away to Wexford Youths.

Jonathan Lunney, Daniel Corcoran (2), Daniel Kelly, Keith Ward, Eoghan Stokes and Cristian Magerusan were all on the scoresheet.

Bray went down 3-1 at home to Finn Harps after extra-time.

The Wicklow side led through Gerald Pender but Sam Todd’s goal brough the tie into overtime.

Michael Place and Jacob Borg scored to put the Ulster side into the second round.

Shelbourne were 4-0 winners over Athlone Town with a Nika Kalandarishvili own goal setting the Dublin side on their way before Patrick Kavanagh, Greg Moorhouse and Lorcan Fitzgerald scored second-half goals.

Strikes from Timmy Molloy and Conor Davis gave UCD victory over Pike Rovers.
