Harrington's '07 success sparked decade of glory
This week in 2007, Pádraig Harrington and Paul McGinley played in the Pebble Beach Pro-Am on the PGA Tour.
On the other side of the world, Darren Clarke and Graeme McDowell were both competing in the European/Asian Tour's Maybank Malaysian Open.
Rory McIlroy? He was a 17-year-old kid, still an amateur, with his sights for the season set primarily on making the Walker Cup team at Royal County Down in September.
Five individual golfers, all of them graduates of the Golfing Union of Ireland system which regulates - and still does - the men's game in the 32 counties of Ireland.
Who could have foreseen the impact they would have on Irish and international golf a decade later? Remember where we stood in that early spring of '07.
No Irish Open winner since John O'Leary in 1982. No Major champion since Fred Daly at Hoylake in 1947.
Within a few months the barriers, psychological and otherwise, were to be kicked down, starting with Harrington's Irish Open win in Adare Manor in May 2007, and his Open Championship victory at Carnoustie.
Within five years, Harrington had three Majors on his golfing CV. McIlroy grew from boy to man and claimed US Open and US PGA titles. McDowell and Clarke joined this exclusive Major champions club with one each.
That 2012 season also brought a special return of the Irish Open to Northern Ireland, with Royal Portrush playing to capacity crowds of around 130,000.
More success was to follow, including McIlroy's British Open and US PGA successes in 2014. Considering we have such a small population relative even to the UK, this little island has punched way above its weight in the sport.
Central to the success has been the individual golfers who triumphed at the highest level.
Harrington broke the mould, and suddenly Major championships were attainable for other Irish players. Based on their achievements, McIlroy, McDowell, and Clarke leveraged their collective influence to do all they could to bring the Irish Open and now the Open Championship to their native soil.
In doing so, Northern Ireland can look forward to a serious economic benefit from the Open in two years' time, if Scotland's most recent experience is any guide.
Figures compiled by Sheffield Hallam University's Sport Industry Research Centre estimate a direct £64m from the 2016 Open at Royal Troon, and £46m in destination marketing benefit from worldwide media coverage of the championship.
Golf is big business, and Ireland, North and South, is a winner in the cash stakes as well as on the professional Tours.
And so, the wheel turns.
