Peter Dawson, president of the International Golf Federation, released the following statement: "The IGF understands the challenges players face in terms of scheduling this summer and it is regrettable to see a few leading players withdraw from this year's Games. The Olympics is the world's greatest celebration of sport and it is exciting and appropriate that golf features in its programme again. Real history will be made at this year's Olympic competitions and it is our belief that the unique experience of competing will live forever with athletes that take part."
Another top player has decided to pass on the Olympics.
Two days after Adam Scott pulled out of the Summer Games, 2010 Open champion Louis Oosthuizen also withdrew himself from consideration because of family and scheduling issues.
“I have always represented South Africa with pride so I didn’t make my decision without a great deal of thought,” he said in a statement released through his management company.
With a few months left to qualify, Oosthuizen, No. 12 in the Olympic rankings, was slated to be on the South African team with Branden Grace. Charl Schwartzel (No. 20) is next in line.
Fiji's Vijay Singh told GolfChannel.com last week that he would not compete in Rio.
