Johnson coasts to victory at Genesis Open

Dustin Johnson went to No. 1 in the world with a worldclass performance at Riviera.

Johnson turned a marathon finish into a Sunday stroll in the Genesis Open in Los Angeles. 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. Johnson won for the fourth time against some of golf’s strongest fields dating to his U.S. Open victory last summer.

Johnson had a one-shot lead when he arrived Sunday at Riviera, which lost 10 hours the previous three days to fog and torrential rain.

He went 49 straight holes without a bogey, a streak that ended on No. 9 in the final round, and he was sloppy down the stretch when it no longer mattered.

Johnson finished at 17-under 267. About the only disappointment was losing a chance to break the oldest 72-hole scoring record on the PGA Tour schedule.

Lanny Wadkins won at Riviera in 1985 at 20-under 264.

Couples had three frontnine birdies and matched Jimenez’s birdies on the par-4 14th and par-5 17th. Jimenez, a stroke ahead of playing partners Couples and Kevin Sutherland entering the round, shot a 71.
