Golf’s return to the Olympics after a 112-year exile was sup-posed to be a global celebration on the grandest stage in sports. That may happen, but three months out from the Rio Games, golf is facing a potential crisis that threatens the credibility of its players as well as the sport’s place in the Olympics. In recent weeks Louis Oosthuizen, Charl Schwartzel, Adam Scott and Vijay Singh have announced that they will not play in Rio. The loss of these Major championship winners is survivable—they are big talents but not exactly big names. The disconcerting fact is that their opting out makes it easier for others to follow suit. “We’re watching this closely,” says a prominent PGA Tour agent who spoke on condition of anonymity. “Some of our guys have been on the fence about going. If more good names pull out, it provides political cover for our players who don’t want to go.”
