This celebration, though, carried a different tune.
The drone of vuvuzelas, all the rage at the World Cup, was replaced by the skirl of bagpipes coming from behind the Royal & Ancient clubhouse. For the 27-year-old South African, the sound could not have been sweeter.
With a performance that rivaled the dominance of Tiger Woods at the home of golf 10 years ago, Oosthuizen led over the final 48 holes and blew away the field by seven shots to capture the British Open.
"To win an Open championship is special," Oosthuizen said. "But to win it at St. Andrews ... it's something you dream about."
The timing could not have been better – one week after South Africa concluded a wildly popular World Cup, and the day Nelson Mandela celebrated his 92nd birthday.
"It felt a bit special, really," he said. "When I walked down 18, I was thinking about his birthday."
