World number one Dustin Johnson began his bid for a third victory in the AT & T Pebble Beach Pro-Am with an impressive round of 67.
Johnson won this trophy in 2009 and 2010 and has had three top-four finishes at the California event in the last four years.
DJ started his latest bid with a five-under round at Spyglass Hill, one of the three courses used over the opening 54 holes before the final-round shootout at Pebble Beach.
It was a fairly simple recipe for the big-hitting American; he birdied all four par 5s and picked up further shots at the fourth and eighth, his only dropped shot coming at the fifth.
That was good enough to leave him tied sixth, just two strokes behind joint-leaders Kevin Streelman and Beau Hossler.
"I could do things a little better. I hit a few bad drives, but got away with them," said Johnson. "But, yeah, I've been driving it well for a while now. For my game, if I drive it well I'm going to play well most of the time."
Johnson now heads to Monterey Peninsula CC for his second round but admits it is the course where his scoring hasn't been as strong.
He added: "Don't know why, I like the golf course. I feel like I should play really well there and I'm going to this year."
Johnson is 100/1 to win the AT & T Pebble Beach National Pro-Am with Rory McIlroy 2000/1 and Jon Rahm 1000/1.
