In the toughest conditions at Firestone in nearly a decade, Johnson made it look easy Sunday when he closed with a 4-under 66 and rallied from a three-shot deficit against world No. 1 Jason Day to win another World Golf Championship.

Two starts, two victories, and now No. 2 in the world.

“It’s the first time I’ve won two tournaments in a row. I mean, that’s big,” Johnson said after his one-shot victory over Scott Piercy.

“I’m excited and looking forward to going over to the British with the golf game in good form.”

He looks like the player to beat at Royal Troon with a frightening combination of driving, wedges and — finally — getting some putts to fall.

Johnson joined Tiger Woods as the only players to capture three of the four World Golf Championships. He won the Cadillac Championship at Doral last year, and the HSBC Champions in Shanghai in the fall of 2013.

His 66-66 weekend at Firestone gave him a 6-under 274, matching the highest winning score at this World Golf Championship since Woods in 2005. Nine players finished under par, the fewest since Woods was the only player to break par in 2007.

Johnson has 11 career victories in his nine years on the PGA Tour.

“I feel great,” he said. “I feel like my game is where it has been all year. I just haven’t been putting quite as well as I’d like. The last couple of weeks, I just putted a little better.”

He made it sound so simple. It looks that way, too. Key to his game was decided late last year to go to a fade off the tee instead of the draw he has leaned on for most of his career. He has that dialled in, and Johnson said when he’s driving it as well as he has been, “then I’m going to be very tough to beat.”

That certainly has been the case in his past two tournaments. He is building a home in south Florida with one room dedicated to golf memorabilia, such as his trophies.

“Hopefully,” Johnson said, “I’ve got to make it bigger.”
