Golf is very popular, and golf tourism is a major industry attracting more than 240,000 golfing visitors annually. The 2006 Ryder Cup was held at The K Club in County Kildare. Pádraig Harrington became the first Irishman since Fred Daly in 1947 to win the British Open at Carnoustie in July 2007. He successfully defended his title in July 2008 before going on to win the PGA Championship in August. Harrington became the first European to win the PGA Championship in 78 years and was the first winner from Ireland. Three golfers from Northern Ireland have been particularly successful. In 2010, Graeme McDowell became the first Irish golfer to win the U.S. Open, and the first European to win that tournament since 1970. Rory McIlroy, at the age of 22, won the 2011 U.S. Open, while Darren Clarke's latest victory was the 2011 Open Championship at Royal St. George's. In August 2012, McIlroy won his 2nd major championship by winning the USPGA Championship by a record margin of 8 shots.
