U.S. Open 2012 LIVE UPATES Round 1: Tiger Woods Among Golf Stars At Olympic Club

Dubbed "Golf's Toughest Test," the annual U.S. Open begins on Thursday at The Olympic Club in San Francisco.

The opening round of the 112th edition of the U.S. Open is highlighted by the highly anticipated trio of Tiger Woods, Phil Mickelson and Bubba Watson, who will tee off at 7:33 a.m. local time. Fresh off his thrilling come-from-behind win at Memorial (which included a remarkable shot on 16 to tie on Sunday), Woods seems as "back" as he has ever been in recent months.

The second marquee trio of the day tees off several hours later and features defending Open champ Rory McIlroy. Although the 23-year-old has struggled in recent weeks, he is coming off a seventh-place finish at the FedEx St. Jude Classic.

McIlroy will be walking the course with Luke Donald and Lee Westwood. Donald arrives at the Olympic Club as the game's No. 1 ranked player but McIlroy and Westwood are right behind him.

Of course, given the Olympic Club's reputation as the "graveyard of champions" it remains possible -- perhaps even likely that someone unexpected will walk away a winner on Sunday.

Could it be 14-year-old Andy Zhang, the youngest player to ever swing at the Open? Or another unexpected player in the field?

@ jillpainter :

Andy #Zhang, the 14-year-old playing in #usopen, has good sense of humor than bunch of guys after his 9-over 79: ``At least I broke 80.''

@ rxy118 :

if the #usopen cut happened at 4:20 pm local time today 12 major winners with 20 majors between them would be going home. #golfishard

@ DaveShedloski :

Zach Johnson unnerved on 15 when spectator had heart attack, stopped breathing. Paramedics revived him. "Hard to hit a shot after that."

RT @garyvansickle: Tiger hit driver only 3 times (9, 10 & 16)--he was surprised how much faster course played today, and adjusted.
