Dustin Johnson doesn’t usually sweat the small stuff. But what about something relatively big – like losing his No.1 spot on the World Ranking?

Well, that’s doesn’t seem to bother him much, either.

Playing this week at the AT&T Pebble Beach Pro-Am, his first US PGA Tour event since his eight-stroke runaway at the Sentry Tournament of Champions last month, Johnson could fall from No.1, according to reports, if he finishes worse than 45th and world No.2 Jon Rahm wins on the Monterey Peninsula. But if Johnson had any trepidation about that, he hid if well during his pre-tournament press conference.

“I mean, it’s just how it goes,” Johnson said. “If he would pass me, he would pass me.”

OK, then. Cool.

Perhaps DJ’s laid-back thinking stems from the fact that it’s hard to imagine him finishing poorly at Pebble, given his previous experience in the AT&T. Two times Johnson has won the title (2009 and 2010), and in 10 starts he has seven top-10 finishes and just one missed cut.

More to the point, Johnson feels confident about his own game, particularly after his performance in Hawaii. (He also finished T-9 while playing in the European Tour’s Abu Dhabi event). Recenlty, he also visited swing coach, Butch Harmon, in Las Vegas to tighten up his swing as he prepares for a stretch of starts that will include defending his titles at next week’s Genesis Open at Riviera and next month’s WGC-Mexico Championship.

Ultimately, Johnson knows that the fate of his ranking really is under his own control.

“If I keep playing well, and keep winning, then, no, I’m going to stay No.1. … If I keep playing like I am, and how I should, then, yeah, I’ll be there at the end of the year.”

No sweat.
