Oosthuizen, the 2010 British Open champion, has not withdrawn from next week’s event in Fort Worth. But his availability has to be considered tenuous, based on his medical condition. Oosthuizen was tied for 32nd on the Nelson leaderboard at the time of today’s withdrawal and, under PGA Tour rules, will share 71st place money at the Nelson with fellow competitors. But his Nelson earnings will be unofficial because he withdrew during the event.
If Oosthuizen is not able to play at Colonial, the tournament will lose its only competitor ranked among the top 10 in the world rankings. Matt Kuchar, the No. 12 player in the world rankings, is the highest-rated player in the Colonial field behind Oosthuizen.
Under PGA Tour rules, Oosthuizen could receive a medical waiver that would allow him to skip Wednesday’s pro-am round and still allow him to compete in Thursday’s opening round at Colonial. Oosthuizen has been playing regularly in recent weeks because his wife in expected to deliver a child in June, clouding his availability for the 2013 U.S. Open and other summer events.
