Johnson grabs No 1 ranking

DUSTIN Johnson secured the world No 1 ranking in style when he smoked the field for a five-stroke victory at the Genesis Open in southern California on Sunday.

With the victory, American Johnson jumps from third to first in the world rankings, supplanting Australian Jason Day, who finished tied for 64th.

“I believe in myself. I think I’m a great player,” a delighted Johnson said after his runaway victory.

Johnson started the final round with a five-shot lead and was never headed after birdies at the first two holes en route to a closing 71 on the storied Riviera course.

Despite two late bogeys, he finished at 17-under-par 267, with Thomas Pieters (63), of Belgium, and American Scott Brown (67) a distant second on 12-under in the event.

Johnson, 32, collects $1.26-million for his 13th PGA Tour victory.
