He hit driver into the burn. The next day, his drive was a few yards short of the burn.

“I hit some irons, and depending on the wind, I’ll probably hit anywhere from ... I’ve hit 3-wood, 3-iron and 4-iron off the tee,” Johnson said. “I like all of them.”

With the wind at his back on the 513-yard 14th hole, Johnson hit 3-iron and wedge.

One thing hasn’t changed about links golf — it’s best to keep the ball out of the pot bunkers, which effectively are a one-shot penalty. The question for so many players is whether that means going down to as little as a 7-iron off the tee (such as the 350-yard third hole) or smashing driver over all the trouble.

Johnson figures he’ll hit driver on half of the holes. U.S. Open champion Brooks Koepka might hit as many as nine drivers.

The conditions are as brittle as Muirfield in 2013, though most comparisons are with Hoylake in 2006, when Woods won the Open for the second straight time by hitting driver only one time all week.

“There’s not a lot of opportunities to hit the driver just because the ball is going to be rolling 80 yards,” Woods said. “It’s just hard to keep the ball in play. Even hitting sometimes 4- and 5-irons, they’ve been running 50, 60 yards. It’s going to be an interesting test to see which clubs we’re going to be using off the tees, and a lot of it is dependent on which way the wind blows.”

Woods had a 2-iron built for him specifically for the British Open, and he wonders how much he’ll even use it. That has been too much club off the tee. Instead, most of his shots are with a 3-iron or 4-iron.

Reed was familiar with conditions the year Woods won at Hoylake, even though he was only 15. Reed won the Junior British Open that summer at Heswall, not far from Royal Liverpool. It was not only dry but extremely hot, and Reed was in rain pants because he didn’t like wearing shorts.

“I’ll never forget hitting the first tee shot and being as young as I was, getting up there, and it was 308,” Reed said. “And I was just like, ‘Wow, I just hit a drive over 300 yards.’ And now I’m hitting 2-irons over 360.”
