Despite the threat of war on the Korean peninsula, the Ballantine's Championship will go ahead as planned.
Some Americans pulled out of the European and Asian Tours event in Seoul because of the situation, but 2010 British Open champion Louis Oosthuizen decided to make the trip.
''I definitely had second thoughts about coming here as Zach (Johnson), Dustin (Johnson) and myself talked extensively the Monday after Augusta about the situation in this part of the world,'' Oosthuizen said. ''They felt more on the danger side because they were Americans coming over here. I said to them that I would wait it out a bit and trust the advice of the European Tour that the tournament won't go ahead if there is a threat.''
Oosthuizen, at No. 7 in the world, will make his debut in the event as the highest ranked player. Paul Lawrie and Y.E. Yang will also play on the Blackstone course.
Yang became the only Asian-born player to capture a major when he defeated Tiger Woods in the 2009 U.S. PGA Championship at Hazeltine, but no South Korean has won the Ballantine's and Yang is hoping to become the first this week.
''As a Korean player and as an individual, I think that I could have done better, so this year I'm going to do my best so that we can keep the trophy here,'' said Yang, ranked 163rd.
