World-number-two Jon Rahm is within touching distance of the top spot currently held by Dustin Johnson, who he has hailed ‘Superman’.

A win at the Farmers Insurance Open would have seen the Spaniard become world-number-one which he looked to be on course for after opening rounds of 68 and 66, before slipping to tied 29th over the weekend.

But Rahm still has his sights firmly set on ousting Johnson, who has sat at number-one for almost a year, from the summit of the rankings.

“I would be the person who defeated Superman,” Rahm joked.

“Obviously I said that as a joke because he won a tournament by eight shots. And he almost holed out a driver from 430 yards!

“Those are things that don’t happen often. It doesn’t mean that he’s unbeatable, because this is golf. Nobody is unbeatable.”

Johnson won four times in 2017 including three-in-a-row in February and March to build a big lead at the top but, with Rahm’s three wins since, that gap has been significantly reduced.

“You’re going to get beat at some point. But definitely we all know he’s a force to be reckoned with. He’s a great player and in great form and in great physical form.

“I mean it wouldn’t make me Superman, because like I said, he is. But I would be the guy who defeated Superman.”

With Johnson sitting out again this week, Rahm has another chance to become world-number-one with success at Waste Management Phoenix Open where he tees off alongside Phil Mickelson and Xander Schauffele at 07:56am MT today.
