In front of a large mobile gallery on a spectacular day on the Monterey Peninsula during the first round of the AT&T Pebble Beach Pro-Am   Dustin Johnson  and Wayne Gretzky joked  their  way through 18 holes and played superbly as a team on the historically toughest golf course of the three layouts used in this event. Gretzky  who plays fast and clutches a cigar as much as he takes hold of a golf club  got things going by making a birdie for the first time in his golf career on the par-5 first at Spyglass and  getting a stroke because of his handicap   the team  was 2-under-par after one hole.
While Gretzky added another birdie on the par-5 seventh and a clutch par on 16 for birdie   Johnson  was overpowering the seaside and tree-lined course with six birdies en route to a 5-under-par 67. As a team  they shot 65.
 Johnson   who kicked off the year with a win in the Sentry Tournament of Champions in Hawaii  is on the first page of the leaderboard and in position to win for the third time here.
 Johnson  and Gretzky have had a visible bond since  Johnson  started dating Gretzkyâs daughter  Paulina  in 2012. Back then   Johnson  was ranked in the 20s â a freak of talent and power who  while winning a tournament a year  fell short of joining the elite class as  he  struggled with  his  short game and course management and didnât buy in 100% to preparation.
A shift to Butch Harmon as his swing coach paid dividends as  Johnson  has become one of the most feared in the game from 150 yards and in.  Johnson  became a gym rat and severely cut down the times  he  painted the town red at night.  Johnson  also became a father  as  he  and Paulina (they are engaged) are the parents of two young boys â Tatum and River Jones.
And  Johnson  has credited Gretzkyâs guidance and advice for  his  ascension up the world rankings.  Johnson  often picked the NHL iconâs brain and said Gretzkyâs support and belief did wonders for  his  confidence. The two quickly became regular golf partners and talked for hours about how to handle sports fame  pressure and expectations  with Gretzky  in  his  mentoring ways  always stressing to never settle.
As  Johnson  changed  his  habits   his  world ranking changed.  He  was 23rd in the world at the end of 2012  16th at the end of 2013  19th at the end of 2014  eighth at the end of 2015 and third at the end of 2016  when  he  won three of  his  17 PGA Tour titles  including  his  first major championship at the U.S. Open.  He  became No. 1 when  he  won at Riviera Country Club in February of last year and has stayed there for 51 weeks as  he âs piled up four more wins.
 He  has no intentions of leaving.
âThere are a lot of really good players that are playing really well right now  so it's going to be tough for me to keep it â  Johnson  said. âBut if I keep playing like I am and how I should  I'll be there at the end of the year.â

As U.S. Secretary of State Rex Tillerson visits the Middle East this weekend  he'll hope to achieve something that has eluded top American diplomats for a generation: sealing a new alliance between Saudi Arabia and Iraq that would shut the doors of the Arab world to neighboring Iran.
The effort to wean Iraq from Iran and bond it to Saudi Arabia isn't new  but U.S. officials are optimistically pointing to a surer footing they believe they've seen in recent months. They're hoping to push the improved relations into a more advanced phase Sunday when  Tillerson  participates in the inaugural meeting of the Saudi Arabia-Iraq Coordination Committee in Riyadh.
 Tillerson  will seek Saudi financial generosity and political support for Iraq  its embattled northern neighbor. Two U.S. officials said  Tillerson  hopes the oil-rich Saudis will contribute to the massive reconstruction projects needed to restore pre-IS life in Iraqi cities such as Mosul and lend their backing to Iraqi Prime Minister Haider al-Abadi. He is treading delicately among a host of powerful countries on Iraq's borders which are increasingly trying to shape the future of the ethnically and religiously divided nation.
 Tillerson 's decision to skip that gathering was widely criticized at the time as a sign of disengagement with his employees  but the official said  Tillerson  adjusted plans to speak by secure telephone to Saudi Foreign Minister Adel al-Jubeir on the Iraq rapprochement.

Navarroâs decision apparently was a reflection on federal officials. It follows release of a memo by  BLM investigator Larry Wooten  that described âa widespread pattern of bad judgment  lack of discipline  incredible bias  unprofessionalism and misconduct  as well as likely policy  ethical and legal violations among senior and supervisory staffâ in the BLMâs Office of Law Enforcement and Security.
 Wooten  wrote that  he  had seen âexcessive force â described officers grinding Bundyâs son Daveâs face in gravel and opined that federal officials were intent on commanding âthe most intrusive  oppressive  large scale and militaristic cattle impound possible.â
In an apparently partisan reference that used a term Hillary Clinton designated for some of Trumpâs supporters   Wooten  wrote that a federal prosecutor said  letâs get these âshall we say Deplorables.â
 Wooten  also wrote that the Bundy case âclosely mirrorsâ the circumstances behind the trial of former Sen. Ted Stevens  R-Alaska.
 Wooten  is no fan of Cliven Bundy who   he  wrote  instead of âproperly using the court system or other avenues to properly address  his  grievances   he  chose an illegal  uncivilized and dangerous strategy in which a tragedy was narrowly and thankfully avoided.â
