First half goals did all the damage as Shamrock Rovers overcame a superb second half fight-back from Sligo Rovers at Tallaght Stadium.
Behind by two at the break, the visiting Rovers were a different team in the second half but were unable to find the net.
Graham Burke had the Hoops ahead from the penalty spot after 26 minutes, while former Rovers striker Aaron Green doubled the lead as the game headed for half-time.
John Russell’s side knocked on the door on several occasions in the second half and were all over their Dublin opponents, a dominant Rovers falling just short in the Dublin sunshine.
Referee Rob Hennessy awarded Shams the spot-kick after the ball hopped up and on to Conor Reynolds’ arm, an unlucky moment on what was another fine performance from a rising Rovers star.
Burke dispatched the penalty to give the hosts the lead while the 2023 champions had their second on 42. Greene turning to finish off a neat flick over the Rovers rearguard from Jack Byrne.
Rovers were a totally different side in the second half and were unfortunate early on not to be awarded their own penalty after a Shams defender looked like he had handled the ball inside Ed McGinty’s area.
McGinty was by far the busier goalkeeper in the second 45 and scrambled to keep out a Matty Wolfe effort. While Owen Elding had a header taken on McGinty’s line by Roberto Lopes as the visitors continued their relentless press for a goal of their own.
Rovers kept trying but couldn’t unlock the Hoops door, going close through Francely Lomboto after Elding’s through ball had caused chaos amongst the Shams’ defence. Ronan Manning then had former Rovers number one McGinty racing across his line to push a late free-kick over his crossbar.
