NORTON, Mass. — Now that he’s finally won again, Dustin Johnson is starting to look as dangerous as ever.

One week after Johnson ended a five-month dry spell brought on by a back injury, he handled the early cold and a steady wind at TPC Boston for a 5-under 66 to take a one-shot lead in the opening round of the Dell Technologies Championship.

And the world’s No. 1 player made it look easy on a tough day for scoring in the second event of the FedEx Cup playoffs.

He started with a 35-foot birdie putt on No. 10. He made the turn with a 6-iron from 220 yards that sailed high and rode the left-to-right wind into 4 feet for eagle. When another big tee shot settled into a divot on the reachable par-5 second hole, he laid up short of the water and still made birdie.

Masters champion Sergio Garcia opened with five birdies on the front nine and shot a 67, as did Jon Rahm, who birdied four of his last five holes in the afternoon as the temperature warmed slightly.

Marc Leishman and Kyle Stanley also were one shot back among the early starters who had to face the surprising chill and wind.
