Brooks KoepkaWorld ranking: 109Formline: 14-55-11-12-MCBest US Open finish: 1st (2017, 2018)Odds: 25-1Koepka has coped well with a disrupted schedule since returning from LIV to the PGA Tour (where he wasn’t exempt into the signature events). There are signs that his putting has improved of late, which had been his Achilles heel earlier in the year. Koepka is a US Open specialist, with his ball-striking and iron approach play strong assets. If the putter works, then a third US Open is possible.Tyrrell HattonTyrrell Hatton with the trophy following his victory at LIV Golf Andalucia in Cadiz, Spain, last Sunday. Photograph: Octavio Passos/Getty Images World ranking: 21Formline: 1-MC-17-5-3Best US Open finish: Tied-4th (2025)Odds: 33-1The Englishman had that so-called new-baby bounce when winning LIV Andalucia upon returning to competitive action after the birth of his daughter. The trick now will be taking that momentum on to Shinnecock Hills. He showed at Oakmont last year that he has developed the patience required for the US Open set-ups. As a three-time winner of the Alfred Dunhill Links, he also possesses a links pedigree that should stand him in good stead.Shane LowryShane Lowry plays a shot from a bunker during a practice round ahead of the PGA Championship at Aronimink Golf Club, Pennsylvania, last month. Photograph: Carl Recine/Getty Images World ranking: 43Formline: 22-44-23-42-30Best US Open finish: Tied-2nd (2016)Odds: 50-1A strong start to the season including three top-10s was followed by a speed bump. One of Lowry’s problems this season has been a tendency to suffer one bad round in a tournament. The final round of the Masters and the second round of the US PGA are cases in point. The Offalyman, though, has managed to get back on track of late. If he can remain consistent through all four days, then, with his ball-striking and iron play, he should be a contender.Scottie SchefflerScottie Scheffler and caddie Ted Scott during last weekend's Memorial Tournament in Ohio.

The US Open is the only major the American has yet to win. With only one victory so far this season (in the American Express Championship) and three runners-up finishes, Scheffler has cut a frustrated figure at times. This was perhaps illustrated by a heated exchange with caddie Ted Scott in the first round of the Memorial. Still, the US Open – and the type of examination it provides – should get his focus back.Adam ScottAdam Scott is a big price to win the US Open but he continues to deliver competitive performances. Photograph: Vaughn Ridley/Getty Images World ranking: 50Formline: 12-MC-24-4-24Best US Open finish: Tied-4th (2015)Odds: 125-1More of a sentimental punt to be honest, given the Australian is playing in his 100th consecutive major championship (joining only Jack Nicklaus in achieving such a feat). Scott, though, has also shown he retains a competitive edge with fourth-placed finishes in both the Genesis and the Cadillac championships this season.
