David Scullion's early strike at The Oval was enough to settle this mid-table bore.
It was a game that will not live long in the memory of the fans who bothered to turn up. The 1-0 victory did at least inch Glentoran to within six points of Oran Kearney's Coleraine.
Scullion got Alan Kernaghan's boys off to the best possible start, scoring after only three minutes. Curtis Allen's industry on the left carved out the chance and, when his cross landed at the feet of Scullion, he gleefully rammed the ball into the empty net.
The same pair almost conjured up a second with a replica move. This time, Allen tricked his way past David Ogilby and, when he whipped in another low cross, Scullion was only inches away from converting.
Coleraine almost self destructed on 16 minutes when goalkeeper Chris Johns spilled a Scullion corner kick with the ball falling for Allen, but Ogilby stepped in to mop up.
Little was seen of the visitors as an attacking force until the 27th minute. Bustling James McLaughlin tried his luck with a vicious 30-yard drive that Elliott Morris did brilliantly to beat away with fisted gloves.
It merely stung the Glens into action at the other end and Scullion was right out of luck when his dipping drive from distance looped inches over the top.
But the visitors again gave the home fans a nervous moment when Ian Parkhill burst into the box, only to see his drive flash inches wide.
Jamie McGonigle almost had Coleraine level on the hour. Having cut in from the right, his shot was superbly pushed away by Morris. Darren McCauley picked up the scraps and cut the ball back for Ruairi Harkin, who pulled his shot horribly wide.
The Bannsiders did get the ball into the net when McCauley finished off a knock down from substitute Sammy Morrow, but referee Steven Gregg disallowed the effort for offside.
Coleraine went in search of a late leveller but Ogilby's effort was superbly clutched by Morris, before the big defender flicked a Ruaidhri Higgins free-kick wide.
