Inst, last season's beaten finalists, qualified for the quarter-finals with a comfortable win over Dungannon Royal at Osborne Park.
The seeded team showed an aggressive quality which helped them to five tries with their half-back partnership of Gareth Lawlor and Matthew Keane controlling the encounter. Lawlor had an exceptional game with accurate kicking and strong defending as well as contributing a try and four conversions.
The home team's first try came from Lawlor who added the conversion. Then centre John McClure crossed to make it 12-0.
The Inst back row put in a lot of work with Ben Alexander and Paddy Anderson much in evidence
The lighter and younger Dungannon team were given few chances to come into the tie as Inst took a 19-0 interval advantage after Anderson scored and Lawlor added the extras.
The trend continued after the restart with Dungannon having to defend for long periods.
But they couldn’t hold out indefinitely and McClure went in for his second while winger Rory Bell scored Inst’s fifth with Lawlor converting both.
In the last play of the game Dungannon were rewarded for all their efforts with a warranted Matthew Montgomery try.
Inst are now at home again for the quarter-finals when they take on Ballyclare High.
