The Emerald Four. After waiting 60 years to see a golf Major back on these shores (Fred Daly 1947), Padraig Harrington led the way in 2007 by winning the Open Championship and followed up by retaining the trophy in 2008, and also adding the PGA the same year. Then Graeme McDowell won the US Open in 2010, and Rory McIlroy followed up by doing the same in 2011. Not to be outdone, Darren Clarke then brought home the Open Championship the same year. A purple patch for golf on this island, with hopefully much more to come.
