Two goals from defender Sean Hargan helped Derry to an extremely easy Setanta Cup victory over Glentoran at a waterlogged Brandywell on Monday night.

The full-time players of Derry never looked in any danger of going down to their lacklustre visitors.
Hargan banged in the opener in the 11th minute and had a free header for his second 10 minutes from the interval.
Gary Beckett scored Derry's third in the 38th minute with Chris Walker bagging a late Glentoran consolation.
Derry, welcoming Glentoran to the Brandywell for the first competitive game for 36 years, started and finished the first half the strongest and looked more comfortable in the dreadful conditions despite playing against a strong breeze.
Pat McCourt was the chief tormentor of Glentoran and it was his corner in the 11th minute that allowed Hargan to rifle home a shot with his right foot at the far post.
Two goals in the run-up to half-time more or less wrapped up the game.
In the 38th minute, a McCourt volley was directed past Elliott Morris in the Glentoran goal by an instinctive outstretched foot of Gary Beckett.
Seven minutes later Derry notched number three after Morris had made a tremendous save to touch a pile-driver from Brian Cash over the bar.
McCourt swung in a beautiful corner and Hargan had all the time in the world to nod home.
Derry should have stretched their lead on the restart when Chris Walker was unfairly adjudged to have felled Cash in the box.
But justice was done when McHugh ballooned the ball over the bar from the spot.
Walker grabbed the Glentoran consolation goal as the game went into added time when he struck a great shot from the edge of the box.
