PGA Tour players try at all costs to avoid 3 putts.
World number two Rahm, playing for the fourth consecutive week, used a four-iron approach shot in the par-five sixth to set up a two-putt birdie and get his round at Pebble Beach going.
The world number one birdied his opening three holes on the Monterey Peninsula course and finished with a total of seven birdies - his best coming with a 20 foot putt on the fourth.
"I hit the ball well. A pretty easy day".
Jack Nicklaus famously once said that he would select Pebble Beach if he only had one more round to play, but do the modern-day players think of the venue so highly? Matt Kuchar and Julian Suri were in a three-way tie for third after posting matching 66s at Spyglass Hill, with Aaron Mise also getting to six-under at the par-71 Monterey Peninsula. As a child, he spent summers in New Hampshire; his grandfather, Maurice, once starred in football at Manchester Central and the University of New Hampshire.
Day, an 11-time US PGA Tour victor, shares 32nd with a host of players including five time major victor Phil Mickelson. He'd never placed higher than third prior to a round than tied him for third two weeks ago at the Farmers Insurance Open. Not only is Schwab the owner of the investment firm that goes by his name, but he is also the benefactor of the Schwab Cup, the yearlong points race on the PGA Champions Tour.
"I'm happy with the round", Johnson told reporters.
"We have played in the European equivalent of Dunhill Links a few times before and we have done well at it, but this is a little bit different", he noted.
Dustin Johnson usually struggles at Monterey Peninsula, but he flipped the script Friday. I'm able to get out of the mechanics of it and just start playing the round and hitting shots.
Johnson was playing in a group that included defending champion Jordan Spieth.
Chez Reavie is dealing with no such inconsistency. He carded a 68 on Thursday at Pebble Beach. He has made 19 consecutive cuts, including all eight events he has entered during the 2017-18 wraparound season.
And there were a lot of positives to take from a sunny day at Pebble Beach with minimal wind.
It's safe to say that many of them sport income levels that make top golfer earnings look modest.
"It can be a hard golf course but it's also a course [that if] you play well, you'll make some birdies", said Lefty. "It's a real treat".
Despite the venue's fame, the event had been mostly ignored by the world's elite in recent years but it has regained its attraction with the top players embracing the pro-am format.
"I just kind of got into a place that I hadn't been before, and I've just got to kind of get back into a comfortable set-up position and then everything will fall through from there". He is playing the tournament for the 22nd time.
