Derry City deservedly over came St Patrick's Athletic in what was dubbed as the FAI Ford Cup dress rehearsal at the Brandywell on a 2-1 scoreline.
Goals from Simon Madden (5) and David McDaid 41) in the first half was enough despite Chris Forrester's second half goal on 57.
The defeat drops St Pat's Athletic down to third place in the Premier Division.
Declan Devine's side broke the deadlock on five when Stewart Greacen's long ball caught out left-back Jake Carroll to find Madden and the City defender calmly side footed home past the out-rushing Barry Murphy.
The Dubliners had a good chance to level things on 34 minutes but Christy Fagan's close range shot was blocked by Stewart Greacen and the striker's second effort from inside the box failed to trouble Gerard Doherty.
Derry doubled their lead on 40 minutes when McDaid fired home his 17th goal of the season when the impressive Barry McNamee cleverly found the striker inside the St Pat's box and he drilled the ball home despite Murphy's best attempts.
Murphy came to his side's rescue minutes later when McDaid reacted first to a miss placed clearance by Connor Kenna, but the frontman's shot was well saved by the alert Murphy.
St Pat's themselves had a glorious opportunity to pull one back on 45 minutes when McDaid's terrible back pass only found Christy Fagan, who skipped round Gerard Doherty, but with Greacen back on the line, the usually reliable striker blasted well over from close range.
Liam Buckley's side did pull a goal back on 57 minutes when Greacen's miss placed pass found Chris Forrester and he hammered the ball home low into Doherty's bottom right hand corner.
James Chambers had a great chance to level things on 64 minutes when substitute Anto Flood saw his glancing header find the midfielder inside the box, but his well hit shot was outstandingly kept out by Doherty.
Derry had another good chance on the counter attack when Stephen McLaughlin latched onto Dermot McCaffrey's pass, but Murphy did well to save the winger's shot, but the keeper nearly turned City substitute Conor Murphy's follow up shot, into his own net, however the ball hit the side netting.
Deep into stoppage time the visitors thought they had claimed a point when Conor Kenna's looping header, which had Doherty beaten, came back off the bar.
