New boss Marty Quinn got the winning start he wanted, but hardly the performance.
Even though Glenavon eased through to an Irish Cup fifth round showdown with either Linfield or PSNI who play tonight, it was hardly awe inspiring.
The amateurs of Newington battled throughout, often muscling the home side out of possession, taking no prisoners in the tackle.
Glenavon huffed and puffed and it took 20 minutes to break down the visitors’ stubborn resistance when Conor Walsh lashed home Eamonn Murray’s corner.
Hugh Dickson caused confusion in the box and when the ball broke kindly Walsh didn’t hesitate to make the most of the chance.
Tony Grant who scored the goal in the original tie before referee Michael McLaughlin called a halt in horrible conditions came off the bench to rescue Glenavon.
Grant was on hand to turn in Trevor Molloy’s cross from the by-line and ease the growing anxiety among the home faithful.
Newington refused to lie down and Sean Adams clawed a goal back with a header which sneaked under Tuda Murphy’s crossbar.
There was to be no fairytale ending for with game entering time added on Glenavon added the third.
Substitute Paul Carvill cashed in when goalkeeper Davy Gibson failed to deal with a cross from Eamonn Murray.
Quinn will be demanding much more as his focus changes from the Irish Cup to the more serious business of dragging the team clear of the relegation zone.
