He is No. 1 in the world, and wants to get major No. 2.

“It’s hard to get No. 2 right now, but it was hard to get No. 1,” Johnson said with a smile. “I think it’s hard to get any of them. It’s just a tough task. There’s only four majors, and to win a major you have to have everything working very well. You’ve got to play really good all four rounds. ... I’d love to get that second one. But it’s one of those things where, like I said, everything has got to work well for four days.”

Jason Day has 12 victories on the PGA Tour, and only the 2015 PGA Championship among majors. He spent 47 consecutive weeks at No. 1 the year after winning his major, and had only one good chance. Justin Rose won the 2013 U.S. Open at Merion for his first major. Rose has won at least somewhere in the world every year since 2010, and he has won on prestigious courses — Muirfield Village, Congressional, Aronimink, Doral — and he was one putt away from adding Augusta National to that list.

But he’s still stuck on one.

So is Adam Scott and Sergio Garcia, Brooks Koepka and Webb Simpson.

Add to that list Louis Oosthuizen, who has been runner-up in all four majors since his 2010 victory in the British Open at St. Andrews.

“I mean absolutely zero, no disrespect to guys that have won one — obviously, myself included,” Thomas said. “But it’s a lot easier to get hot one week than it is to do it again and win another major. Because when you’re a major champion, you have more asked of you. You have more expectations on yourself, more expectations from other people to where if you do get in the hunt, then you’re asked, ‘How is it going to feel to get your second major?’ You’re constantly reminded of that.”

The top players when Woods was in his prime years were Phil Mickelson, Ernie Els and Vijay Singh. Woods rarely fails to mention Retief Goosen on that list, mainly because when Woods was at his best, Goosen was the only other player with multiple majors. He won his second U.S. Open at Shinnecock Hills in 2004.

Seventeen players at Shinnecock Hills this week have only one major and would love to add another.

If they don’t? It’s still better than being on that other list occupied by the likes of Rickie Fowler, Hideki Matsuyama and Jon Rahm.

They’re young. But they would settle for one.
