GAA round-up: Red mist descends in Armagh, Rebels enjoy 31-point victory and Dubs begin with a win
Cork had a facile start to 2015 when they ran out 37-point winners over Mary Immaculate in the McGrath Cup today while Kieran McGeeney opened his Armagh managerial career with a defeat.
On the half hour mark the Rebels held a 0-09 to 0-01 advantage but two goals in as many minutes finished the contest before the break, with Jamie O'Sullivan and John Hayes raising the green flags as Brian Cuthbert's side led by 15 points at the interval.
There was no let-up in the second half as Fiachra Ó Deasuinaigh, Eoin Cadogan, Colm O'Driscoll (2) and Donncha O'Connor ensured a facile victory on a final scoreline of 7-20 to 0-04. In the other preliminary game Waterford defeated UL 1-16 to 2-07.
In Ulster things were far closer between Armagh and Tyrone as Kieran McGeeney's first game in charge of the Orchard County ended in defeat in the McKenna Cup.
Colm Cavanagh and Ciaran Mc Keever receive a red card each following an incident after nine minutes and just a point separated the sides at the Athletic Grounds at half-time, with the home side enjoying the narrowest of leads, thanks in part to some wayward shooting from Mickey Harte's side.
They hit eight in the first half compared to just a solitary wide from the hosts.
Less than ten minutes into the second half and Armagh were reduced to 13 men when Finnian Moriarty was given his marching orders.
An Aidan McCrory put the Red Hand into the lead, but Eugene McVerry responded five minutes later in a game that ebbed and flowed.
However it was Tyrone that picked off the final three scores of the game through Peter Hughes, Cathal McShane and a Darren McCurry point to run out winners 1-12 to 1-10.
Elsewhere in the McKenna Cup, Cavan, Derry, Fermanagh and Antrim enjoyed opening round victories.
2013 All-Ireland champions Dublin made a winning start to 2015 as they proved too strong for Maynooth University at Parnell Park today.
Manager Jim Gavin saw his charges run out seven point winners against the students in the O'Byrne Cup Group A encounter.
The Dubs led at the break 1-07 to 0-03 with a goal from Eoghan O'Gara putting daylight between the sides with the first score of the game after just three minutes and the seven point cushion was held until the final whistle.
Elsewhere in the O'Byrne Cup there were big wins for Offaly and Kildare, while the students of UCD got the better of Carlow. Wicklow had five points to spare over Carlow IT.
In Connacht, Mayo edges past NUIG, Roscommon were too strong for Sligo IT and reigning FBD champions Leitrim had a facile win over GMIT. Kevin Walsh's first game in charge of Galway resulted in a nine-point victory over Sligo.
