I think that the young guns have clearly now raised their hands in the golfing world, and are starting to win, not just more and more tournaments, but the majority of the bigger tournaments.
Just to take a South African perspective at the US Open, Ernie Els missed the cut and Retief Goosen, while doing well on the last day, finished fairly far back. Tied in 9th place, as the best South Africans, was the reigning US Masters champion, Charl Schwartzel, and the reigning British Open champion. Louis Oosthuizen. In other words, they are two young South African talents that once again beat the former big names in a major tournament, namely Els and Goosen.
Likewise, the best Australian at the moment is Jason Day, Rory MciIroy at 22 romped home as the winner and most of the 40 plus veterans, despite their experience of such pressure situations, did not feature as well as the young guns.
