The world's number one golfer, the Irish Open at Royal Portrush, Olympic and Paralympic medal winners, a table-topping rugby team, Donegal's All-Ireland winners and the best ice hockey side in Britain provided some of the many memorable sporting moments for Northern Ireland in 2012.

In the Paralympics, the local headlines were dominated by runners Jason Smyth and Michael McKillop.
Smyth, who narrowly missed out on qualification for the Olympics, retained his two sprint titles and McKillop took double gold as well in his 800 and 1500 metres categories.
Bethany Firth from Seaforde won gold in swimming, Portaferry cyclist James Brown took bronze with partner Damien Shaw in the tandem road trial and Eilish Byrne from Armagh also got bronze in the equestrian dressage.
Golfing superstar McIlroy did not have much joy in the first three majors of the year - tied 40th at the Masters, a missed cut in his US Open title defence and a share of 60th place at the Open at Royal Lytham and St Annes.
But it all came right for the Holywood man as he won his second major with a runaway triumph at the US PGA and ended the year as world number one, topping the European and United States money lists.
McIlroy won by eight shots in the US PGA at Kiawah Island in August to secure his second career major - in 2011 he had secured the US Open by a similarly massive margin.

A routine home win over Italy was then followed by a frustrating 17-17 draw in Paris as the Irish wasted a glorious chance for a rare away win over the French.
Declan Kidney's side comfortably accounted for Scotland but the Six Nations campaign ended on a hugely disappointing note as England's scrum dominance led to a chastening 30-9 defeat at Twickenham.

Ireland's cricketers began the year by safely qualifying progressing from the World Twenty20 qualifier in Dubai but the awful summer weather meant a frustrating finish to the season for Phil Simmons' squad.

The rain even followed the Irish to Sri Lanka in September as their decisive clash with the West Indies had to be abandoned which meant for an early exit from the World Twenty20 after their opening defeat by Australia.

The Irish men endured particular heartbreak as they suffered a final-second defeat by Korea in a game where they winners would have secured a place in London.
