CARNOUSTIE, Scotland — The leader in the Carnoustie clubhouse after the first wave of tee times in the second round of the British Open Friday is named Johnson.

No, not Dustin Johnson, the No. 1 ranked player in the world, winner of 18 career titles and the unanimous pre-tournament betting favorite to hoist the Claret Jug on Sunday.

Dustin Johnson, at 6-over par through his two rounds at Carnoustie the last two days, will be headed back to the US with a missed cut.

The leader of the 147th Open Championship is Zach Johnson, the winner of the 144th Open Championship, played at St. Andrews in 2015.

“I’ve been called ‘Dustin’ many times,” Zach Johnson said after shooting a 4-under-par 67 Friday to get to 6-under for the tournament. “I doubt he’s been called ‘Zach’ that many times. Maybe some people do assume, when they see the name up there, that it’s Dustin. How many tournaments has he won, 20?’’

Eighteen.

“There you go,’’ Johnson said. “It’s a pretty safe assumption. (But) I guess Johnson & Johnson is doing okay (so) I don’t care.’’

Nor should he. Zach Johnson, winner of a Masters and that British Open, has put himself in fantastic position to have his name engraved on the cherished Claret Jug again.

When he finished, Johnson was one shot ahead of Tommy Fleetwood, who is trying to become the first Englishman to win a British Open since Nick Faldo in 1992.

Fleetwood, who owns the competitive Carnoustie course record of 63 when he shot 9-under-par at last year’s Dunhill Links Championship where par was 72, not the 71 it is for the Open, shot a 6-under-par 65 on Friday.

“It’s no course record, but it will do for today,’’ Fleetwood said with a smile. “It was a spirited effort.’’

It was a spirited effort in some less-than-spirited weather, with an annoying steady rain falling throughout the morning session.

Fleetwood’s round was buoyed by the final-round 63 he shot at Shinnecock last month, nearly stealing the US Open with the charge from behind.

“The round itself was just something that was very special and very close to being a one-and-only round,’’ Fleetwood said. “But to be a part of history was really cool. I don’t really think you can get a much tougher test than Shinnecock or Carnoustie. You’re on the toughest test in golf.’’

Asked about becoming the first Englishman to win a British Open in 26 years, Fleetwood said, “It would be very special. I can’t lie about it, if I could pick one tournament in my life to win, it would be the Open. I’ve never been anywhere near (winning it) before. So far for two rounds, I’m up there on the leaderboard.’’

So, too, is Rory McIlroy, who shot a second consecutive 2-under-par 69 to stand at 4-under par entering the weekend.

“I’m in a great position going into the third day,’’ McIlroy said. “I feel like I played in the toughest of the conditions, and definitely our side of the draw, we had to sort of tough it out a little bit. It was a little more difficult. So I’m happy to be in with a shot. Hopefully, I can go out and play well again (Saturday), and then that will be a big chance going into Sunday.’’

Tiger Woods, who teed off in the morning and finished in the afternoon, kept himself in contention with a second consecutive even-par 71 to stand six shots out of the lead when he walked off the course.
