“It was the perfect type of weather conditions to make a comeback,” Rose said. “This is the type of day when you are playing with a lead, every hole seems difficult. Obviously, someone is still capable of playing a special round of golf. And my back nine was just amazing today.”

The signature shot was a 5-iron he purposely threw up into the wind on the par-3 17th and watched it land some 3 feet behind the hole. That gave him the lead over Stenson, and no one caught him.

Stenson, who tied for the lead with a two-putt birdie from just short of the 16th green, ballooned his tee shot on the 17th and was well short and to the right, leading to a bogey. Koepka was within one shot of the lead until the wind switched on him at the 15th and deposited his shot into a plugged lie in the bunker. He blasted out to the fringe and took three putts from 30 feet for double bogey.

Rose won for the first time since capturing the gold medal at the Olympics last summer in Rio de Janeiro. He now has won every year since 2010.

The HSBC Champions sure didn’t look like a tournament where he would keep that streak going, not when he was eight shots behind going into the final round against Johnson, who has been No. 1 in the world since running off three straight victories against strong fields in the spring.

Nothing went right for Johnson.

He made bogey on No. 1. He drove into the water on the par-5 second and had to scramble for bogey. Still, he made the turn at 15 under and had a three-shot lead, and he was driving it down the middle and long on every shot. He fell apart on the par-5 14th, when he chunked a short iron for his second shot and had to get up-and-down for par, bogeyed the 15th from the bunker, and then hooked an iron into deep rough on the 16th.

His flop shot was a yard short of being perfect. Instead, it went into a bunker and he made another bogey.

“That wind was blowing hard,” Stenson said. “On this golf course, if you hit the wrong shot at the wrong time, it’s going to penalize you. Certainly it penalized DJ a number of times today. That’s why he came back to the rest of us. I played pretty strong, and then I hit one bad shot with possible the wrong club on 17. That kind of ended my chances to win the golf tournament.”

Rose won his second World Golf Championships title — the other was at Doral in 2012 — and moved to No. 6 in the world. Johnson gets a month off to consider one that got away from him in an ugly manner.
