Louis Oosthuizen came within a whisker of causing an upset at the recent Abu Dhabi Golf Championship Qatar Masters nearly catching long-time leader Paul Casey with a brilliant final round 64 at the immaculate Abu Dhabi golf club in the United Arab Emirates.  Paul Casey had led by several shots throughout the round, but a nervy back nine with 3 bogeys saw his lead slip to 1 shot and the brilliance of the young South African coached by Pete Cowen turned what was going to be a procession by Casey into a very exciting finish.
