Part one: Aiken to Leishman
The brittle South African has won three low-grade European Tour titles, but struggles in elite company. He has US Open form figures of 25-MC.
Qualified for the 2009 US Open at Bethpage as a promising amateur. Missed the cut and has struggled to make an impact since.
Star Stateside junior who came through sectional qualifying. The 18-year-old amateur can be ignored in the outright betting.
Byeong Hun An
Talented Korean who won the 2015 BMW PGA Championship by six shots. In tidy form but has missed eight cuts in 12 Majors.
The 32-year-old teaching pro won the Tacoma CC sectional qualifier to book a US Open debut. One of several no-hopers who have sneaked through the qualifying process.
The South African has won six times on the Sunshine Tour, but has failed to impress away from home. Came through the Walton Heath qualifier.
The 2015 US Tour Rookie of the Year won his maiden title last season in the St Jude Classic and successfully defended it last week. He is capable of entering the Erin Hills equation.
Flaky Frenchman sneaked into the field as an alternate. Winless on the European Tour for almost four years.
Lanky Michigan journeyman who is making his Major debut courtesy of success in a qualifier. Won on the Web.com Tour last year, but lacks ability.
The intense American won the 2011 USPGA in his first Major appearance, but his form has dipped sharply since the ban on anchored putters.
The 27-year-old Carolinian made his US Tour breakthrough in the Heritage in April, having won three times on the Web.com Tour last year. Making his US Open debut.
The Argentine veteran, 48 in September, won the 2007 US Open and the 2009 Masters, but struggles to make a cut these days.
The genial Spaniard has won twice on the European Tour, but a suspect temperament and short game mean he is difficult to trust in Majors. Folds from the front too often.
The porky sectional qualifier is a big-hitter who should enjoy the set-up at Erin Hills, but back problems have been hampering him for some time.
The Englishman, a Major maiden, turns 40 in July. Has won only once in the States and seems likely to get the jitters if a trophy chance presents itself.
The 31-year-old Texan is a US Tour maiden with limited ability and some woeful recent form.
A sweet swinger who has been threatening a US Tour breakthrough having overcome injury problems. Good enough from tee to green to challenge for a top-20 finish.
A quality ball-striker who has proven himself in US Open combat. Finished third in 2011 and tenth in 2012. Won his maiden US Tour title in April’s Texas Open. Warmed up with a share of fourth in the St Jude Classic on Sunday. A serious contender.
The 2009 Open champion is starting to find some encouraging form again on the US Tour aged 44. Was third in the 2001 US Open.
Is there a clue in the surname? No – he is a 21-year-old amateur sectional qualifier who is making up the numbers.
The Swede is a two-time US Tour champion, but the last of those was in 2008. Has little to offer aged 43.

The eccentric 23-year-old Californian is finding his feet again after a short spell in the doldrums. Tied for 15th in last year’s US Open. Was a second-round loser in the 2011 US Amateur at Erin Hills.
The Mexican number one will come into the field if and when Phil Mickelson officially withdraws. Mickelson is hoping a first-round weather delay will allow him to attend his daughter’s high-school graduation and still make it back to Erin Hills in time to compete. It is much more likely Diaz, the world No. 396, will get the gig.
Sectional qualifier who has as much chance of winning the US Open as TV presenter Diana Dougherty. Only just inside the world’s top 2,000.
The Welshman still has enough about him to compete on the European Tour aged 43, but he has never been close to Major-winning class.
The accurate American recovered from a third-round 77 to win the Memorial. The 2013 USPGA champion has finished in the top eight in three of the last five US Opens. A solid top-20 option, but surely his putting weakness rules out a title challenge.

The South African legend is a fading force at 47. The US Open champion in 1994 and 1997.

The 2003 US Amateur looked a potential world-beater when winning three times on the Web.com Tour in 2007. Further success has not come easy, injuries not helping, and a 33rd birthday arrived yesterday. The talented Aussie is the most interesting sectional qualifier.
The Southport lad is a greens-in-regulation machine enjoying an excellent season. He tied for 27th in his only US Open, but a lack of Stateside success is off-putting.
The colourful Californian takes a hugely impressive set of 2017 stats to Erin Hills and he won the Honda Classic in February. He was a flopping favourite in Memphis last week but has to be on the shortlist.
The US Ryder Cup captain has understandably lost his playing form this season. Erin Hills likely to prove a slog for the short-hitting 47-year-old.
The Masters champ has failed to post a competitive 72-hole total in his three tournaments since winning the Green Jacket in April, but has delivered bursts of brilliance. Expect a more focused effort this week from the maturing Spaniard, who has five US Open top-tens to his name.
The 34-year-old journeyman lost his US Tour card and has been struggling on the Web.com Tour. Easy to rule out.
The 2009 US Open champion has shown enough this season, particularly at Bay Hill and Sawgrass, to suggest he could contend again. Strong from tee to green, but a poor putter.
The Oklahoman is making his US Open debut after coming through sectional qualifying. Any price you like.
The South African was one of the stars of 2015 and 2016, but his form has dipped this season. His best performances have come in the last three months, though, so maybe he is peaking at the perfect time. Has finished fourth and fifth in the last two US Opens.
The 2016 Amateur champion. The Hampshire lad missed the cut in the Masters in April. Another weekend off is likely on his US Open debut.
Sectional qualifier making his US Open debut. Likely to be packing his bags on Friday.
The Argentinian is a consistent ball-striker with the game to handle a US Open assignment. Has played in six Majors without missing a cut. A solid top-20 finish option.
The former FedEx Cup champion has teed up in 30 Majors without ever threatening to win one. Likely to play well without getting in contention.
The 29-year-old Canadian made his US Tour breakthrough in March. His form has dipped since and he is playing in only his fourth Major.
The 26-year-old was the low amateur in the Masters in April and earned a US Open spot through a sectional qualifier. He insists his future is in business, not golf.
The Georgian holed a long putt on the 72nd hole to win the Wells Fargo Championship a month ago. Almost certainly lacks the all-round polish to become a Major champ.
The 39-year-old amateur is playing in his second Major, having missed the cut in the 2015 Masters.
The diminutive Englishman has surged up the world rankings and has twice finished fourth on the US Tour this season. He was fifth in the 2016 Open and is making US Open debut. Has gone slightly off the boil in the last two months.
The putting wizard has missed two cuts in a row, losing his form at a bad time. He was a second-round loser in the 2011 US Amateur at Erin Hills.
The Masters pacesetter eventually dropped to 22nd spot. Has not bettered 37th in five US Open starts. Solid but unspectacular since Augusta.
The erratic powerhouse closed with an 84 when leading the Players Championship last month, finishing 41st. Difficult to trust.

The Japanese raider has won 16 times in his homeland, but never bettered 29th place in a Major.
The 24-year-old came through the Japan qualifier. Has won once on the Japan Tour and is making his US Open debut.
The German qualifier has won three times on the Web.com Tour, his latest victory coming on Sunday. Carded a 58 on his way to winning his maiden title. He was a second-round loser in the 2011 US Amateur at Erin Hills. An interesting runner making his second US open appearance.
The world number one was awesome for the best part of two years before missing the cut by five shots in the Memorial last time out. The defending champion has US Open form figures of 4-2-1 and is the overwhelming favourite to lift the trophy on a course which suits.
The Johnson with much less chance of success. The 41-year-old has been unimpressive since winning the Open at St Andrews in 2015. A short-hitter and likely to struggle.
Beef came through the Walton Heath qualifier to secure a second US Open start, having finished 54th on his debut last year. The Barnet blaster is enduring a poor season.
The 2014 US Open champion is winless since his Pinehurst glory. There is nothing in his recent form to indicate he will stop the rot at Erin Hills.
The 27-year-old American won on the Japan Tour for the first time last month. Came through the Japan qualifier to earn a US Open debut.
Si Woo Kim
The Korean youngster won the Players Championship in hugely impressive fashion last month. Has been battling a back injury all season. A class act but has serious fitness issues.
The 25-year-old Korean finished tied for second in the St Jude Classic on Sunday, but little can be expected on his Major debut.
The Carolinan won his second US Tour title last month, fending off Jordan Spieth and Jon Rahm at Colonial. Full of form, but Erin Hills is not an ideal layout for him.
The accurate Scot has been short of sparkle since his Ryder Cup snub. Another week of struggle seems on the cards.

The power-packed 27-year-old has solid form of 4-18-13 from the last three US Opens. He was fifth and fourth in the last two USPGAs, and 11th in the Masters in April. Clearly becoming a man for the big occasion and is well suited to Erin Hills.
The sectional qualifier is making his third US Open start. He squandered a five-shot halfway lead to finish fourth in the Byron Nelson last month, remaining a US Tour maiden.
The talented Texan won twice on the Web.com Tour in 2012, but has failed to train on. Maybe US Open qualification will relight his fire.
The consistent US Tour performer finished fourth in the Masters in April and fourth in the Memorial last time out. Has solid form from the last seven US Opens (6-14-27-28-12-12-46), but this long, open venue seems an unlikely place for a Kooch Major breakthrough.

The 19-year-old amateur battled through the Dallas sectional qualifier for a US Open debut.
