Does golf belong at the Olympic Games?

The 40-year-old American, who claimed his second Major championship when he triumphed at St Andrews 12 months ago, believes minority sports are more deserving of prominence in an event that only comes around every four years.

"I don't know if golf has its place in the Olympics now," Johnson told a news conference on Monday. "We are relevant 24/7, 365 days of the year, if that's your barometer and criteria relevancy.

"I think golf fans really look forward to the Majors ... and the Ryder Cup in particular. I know, as a player, those are my main motivations.

"No offence to the Olympics, but I'd rather be on the Ryder Cup team. As an American golfer I have that opportunity and that's what I'd rather," added Johnson.

World number one Jason Day, second-ranked Dustin Johnson and number four Rory McIlroy are among several top players to have pulled out of the Olympics because of fears over the Zika virus.

Zach Johnson believes, however, that it is too early to tell how the string of high-profile withdrawals will affect golf's return to the Games.

"Will it fit in? Is there any motivation? Is there going to be any tradition? ... it's yet to be seen," said the 2007 U.S. Masters champion.

"The Olympics to me is certainly the premier event when it comes down to a lot of different sports. Those sports should be at the forefront, wrestling, all those sports that just don't get the recognition the mainstream sports get.

"Those athletes train essentially for three or four years for that one opportunity and one week. You can argue that basketball and soccer, do they really need to be in there either?" said Johnson.

"My guess is they want a World Cup before they want a gold medal, they'd want an NBA Championship before they want a gold medal."

Johnson, who will play alongside Australian Adam Scott and Henrik Stenson of Sweden in the first round of the Open on Thursday, says he is an avid television viewer every time the Games comes round.

"You can see the passion for the Olympics is there, pretty much regardless of any sport, but especially the ones that are just not mainstream, and I love that," he explained.

it is unfortunate that the Zika virus has prevented the world's leading four players from travelling to Rio, but you really do wonder if they care too much about the Olympics when it has never been part of the golfing calendar.

The US PGA Championship has been moved forward by two weeks to the last week in July to accommodate those players going to Rio, but you can be sure the priority for the game's finest figures is winning Majors. An Olympic gold is a novelty, and the purpose of landing one must also be up for some debate. It is a distant second to Major championship golf.
