Larne guaranteed their top six place in style with a comfortable 5-0 win at home to Warrenpoint Town.
Tiernan Lynch's men were in control throughout and only for some wayward finishing would have won by an even great margin on the night.
Their victory, coupled with Glenavon's heavy defeat at Seaview, means a top half finish is guaranteed ahead of the split.
Goals from Josh Robinson and Andy Mitchell in the first half and Ronan Hale, Marty Donnelly and Davy McDaid in the second wrapped up the victory as they also closed the gap on the top three.
Larne first threatened with seven minutes on the clock when Marty Donnelly's right-wing corner fell to Dean Jarvis, who saw his effort cleared off the line.
From the corner Larne took the lead. Donnelly's delivery this time caused havoc in the Town defence, with defender Josh Robinson heading home.
Larne doubled their lead with 20 minutes on the clock. Ronan Hale beat goalkeeper Andy Coleman to the ball and was clipped by the stopper, with Andrew Davey pointing to the spot despite protests it was outside the box. Andy Mitchell stepped up to slot home the resulting penalty.
Ronan Hale went close on three occasions.
Firstly, on 22 minutes, his sharp turn clear of Danny Wallace got him behind the Town defence, but steered his shot just wide. Josh Robinson's header from another Donnelly corner then clipped the bar, before Hale threatened again, heading just over from John Herron's pacey cross.
Hale flashed one across the face of goal after cutting in on the left flank on 31 minutes as Larne continued to push to add to their tally.
They did exactly that, however, with two goals in the space of three minutes at the start of the second half.
Firstly, with 49 minutes gone, Fuad Sule produced a perfectly-weighted ball over the top of the Warrenpoint defence to put Donnelly in and the little forward cushioned the ball high over the advancing Coleman and into the net.
Three minutes later Hale deservedly got his name on the scoresheet.
This time the Invermen attacked down the left flank, with Dean Jarvis cutting the ball back from the byline into the path of Hale, who took a touch before firing low across Coleman into the bottom corner.
Warrenpoint, who are now without a win in 11 matches, had a chance to reduce the arrears with 16 minutes left but Conor Devlin blocked bravely from defender Daniel Bryne.
The home side finished off the scoring on the stroke of the 90 minutes, with Davy McDaid lobbing over Coleman from a tight angle inside the box.
