Dustin Johnson went to No. 1 in the world with a world-class performance at Riviera.
Johnson turned a marathon finish into a Sunday stroll in the Genesis Open. He finished the third round in the morning with a 7-under 64 to build a five-shot lead, stretched it to nine shots at one point in the final round and coasted home to a 71 and a five-shot victory.
"It sounds good," Johnson said when asked about being the top player in the world. "I played really great all day. I couldn't have driven it any better. That was a big key."
Johnson became the 20th player to reach No. 1 since the world ranking began in 1986, ending Jason Day's 47-week stay at the top.
"He deserves it because he's been playing great golf," Day said.
Johnson won for the fourth time against some of golf's strongest fields dating to his U.S. Open victory last summer. All he cared about Sunday was winning at Riviera, one of his favorite courses where he has had chances in four of the last five years.
