Darren Dennehy's goal mid-way through the second half handed Limerick a 1-0 win Sligo Rovers at the Showgrounds.
During an entertaining opening half, it was the away side who threatened first. Former Rovers winger Daniel Kearns pulling Billy Dennehy's cross back into the path of Shane Duggan who fired narrowly wide.
Rovers gave debuts to four starters including former Liverpool striker Adam Morgan. The 23-year-old striker was just short of Rhys McCabe's ball to the back post on 19 minutes. While Kearns forced a great one-handed save from Rovers goalkeeper Micheál Schlingermann mid-way through the half.
Ali Roy, another Rovers debutant looked lively on the left side for Ger Lyttle's charges. The Scot fired narrowly wide from Caolan McAleer's cross 25 minutes in.
The Hearts loanee was involved again before the break. His neat turn of pace coupled with some trickery saw him glide past his marker, but he could only look on as his shot sailed over Brendan Clarke's crossbar.
Rovers finished the first 45 the stronger and their best chance of the half fell to Eduardo Pinceli. Another winter signing, the Brazilian's improvised header with his back to goal dribbled past the Limerick post from a whipped McCabe free-kick.
Limerick, somewhat against the run of play, hit the lead on 63. Dennehy rising highest to nod Duggan's cross past the flailing arms of Schlingermann.
Tommy Barrett's team continued to create. Substitute Kilian Cantwell worrying Schlingermann with an effort before the Mayo man denied Kearns once more with an acrobatic save seven minutes from time.
