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.
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.
