Stephen Kenny's Shamrock Rovers claim a much needed three points in the Airtricity League with a 1-0 win at his old club Derry City.
Midfielder Ronan Finn was the champions’ match winner, his second half strike was enough to separate the sides, as Rovers moved to within seven points of leaders Sligo Rovers.
For City, their Achilles heel came back to haunt them when they failed to create anything clear-cut in the final third of the pitch, while they can't stop leaking goals
The Candystripes went close on five minutes when Dermot McCaffrey and Stephen McLaughlin linked up well, before the winger's cut-back found Barry Molloy, but the skipper's shot from 20 yards flew well over.
Rovers were fortunate not to be reduced to ten men on 14 minutes when Craig Sives brought down David McDaid with the striker racing clear in on goal, but referee Derek Tomney only cautioned the centre-back.
The Dubliners should have taken the lead on 25 minutes when Dermot McCaffrey's terrible back pass found Gary Twigg, but fortunately for the defender the league's leading marksman saw his shot saved by Gerard Doherty.
Just after the half-hour mark City's injury nightmare continued when Patrick McEleney had to be stretchered off and replaced by Barry McNamee, following a challenge on Chris Turner.
On 48 minutes a fantastic strike by Ruaidhri Higgins nearly gave his side the lead but Rovers keeper Jannson made a tremendous save to tip the ball over the bar.
The deadlock was broken on 53 minutes when Gary McCabe squared the ball to Ronan Finn and the midfielder got away from Barry McNamee, before lashing the ball in off the underside of the bar to give Doherty no chance.
In stoppage time veteran defender Eddie McCallion came off the bench to play his final game for his home town club, as he moves to Glenavon.
Right at the death City thought they snatched a point when McCaffrey's corner found Ryan McBride at the back post, but the big centre-back headed wide.
