Tacoma - Quick formguide ahead of the 115th US Open which starts at Chambers Bay, Tacoma on Thursday:
RORY MCILROY (NIR); world ranking -1, Major wins -4
The world No.1 and tournament favourite says he has successfully recharged the batteries after missed cuts in his two last outings in Europe. Won twice in the USA prior to that form dip. Won the US Open in 2010, the first of four major titles
JORDAN SPIETH (USA); world ranking -2, Major wins -1
This year's Masters winner and still only 21, missed the cut at the Players Championship, but has two top three finishes in his last three tournaments and a caddie with useful local knowledge on his bag.
BUBBA WATSON (USA); world ranking -4, Major wins -2
The two time Masters champion is one of the biggest hitters in the game and the consensus is that a big hitter off the tee will win it this week. But has not played since a tie for 42nd at the Players Championship.
JUSTIN ROSE (ENG); world ranking -5, Major wins -1
Rose won the 2013 US Open at Merion for his first major title and has been in top form this year after an injury-hit 2014. Tied for second at the Masters in April and then won the Zurich Classic and placed second in The Memorial.
DUSTIN JOHNSON (USA); world ranking -7, Major wins -0
The big-hitting Johnson is seen by many as long overdue his first win in a major, having come close previously in all four of the Grand Slam tournaments. Played well at the Byron Nelson and the Memorial, but withdrew through illness at the St. Jude Classic last week.
RICKIE FOWLER (USA); world ranking -8, Major wins -0
Another US player prowling on the edges of a major win. Became just the third player in history last year to place in the top five in all four majors in same year. Won the Players Championship last month.
PHIL MICKELSON (USA); world ranking -17, Major wins -5
The 45-year-old Mickelson will be the crowd favourite to win, having placed second a record six times at the US Open and he needs just this one to complete his career Grand Slam. Been in poor form so far this year, but a closing 65 to tie for third at the St Jude Classic last week augurs well for him.
TIGER WOODS (USA); world ranking -195, Major wins -14
Six months shy of his 40th birthday, Woods is struggling to revive his career after a succession of injuries led to a remodelled swing. Endured a career worst 85 in the third round of The Memorial and finished dead last. Has not played since then. Has won US Open three times, the last time six years ago.
MARTIN KAYMER (GER); world ranking -19, Major wins -2
The German was a wire-to-wire winner at Pinehurst last year clinching an eight-shot win. But has had a miserable run of late with a rash of missed cuts and poor finishes. Needs a rapid turnaround of form to have any chance at Chambers Bay.
HIDEKI MATSUYAMA (JPN); world ranking -14, Major wins -0
Asia's top player and biggest hope in years is up to a career-best 14th in the world rankings and Rory McIlroy for one believes he is on the verge of a big win. Took fifth place in the Masters and tied for fifth in his defence of the Memorial title.
