Justin Thomas will defend his US PGA Championship title at Bellerive Country Club as the year's final major takes place from August 9-12.
Sky Bet are paying eight places on all each-way bets ahead of the action and here, we take a look at 10 of the popular contenders in the betting.
Dustin Johnson (8/1)
The world number one missed the cut in the Open at Carnoustie, but that is the only early exit he has made from 14 events in 2018 and he bounced straight back to claim a third win of the season in the Canadian Open. In 12 completed strokeplay events the former US Open champion's worst finish is a tie for 17th.
Rory McIlroy (12/1)
McIlroy has won the US PGA twice, although his dramatic victory in the dark at Valhalla in 2014 remains his last major title to date. However, the former world number one finished second in the Open and his game should be suited by the conditions in St Louis. He needs to find the putting touch which fired him to victory at Bay Hill earlier this season.
Justin Thomas (12/1)
Just days before his PGA defence at Bellerive, the 25-year-old won his first World Golf Championship title as he impressive led the WGC-Bridgestone Invitational from the front, finishing four shots clear. It was his fourth PGA Tour triumph since landing his maiden major at Quail Hollow and it's no surprise to see him joint second favourite with Rory McIlroy at 12/1.
Brooks Koepka (20/1)
The double US Open champion has also compiled a consistent record in the other majors, his tie for 39th in the Open marking the first major since the 2016 Masters that he had not finished 13th or better. The big-hitting American has also been 15th or better in the last four US PGA Championships, including top fives at Whistling Straits (2015) and Baltusrol (2016).
Jason Day (20/1)
Jason Day knows what it's like to be a PGA Championship winner having ended his wait for a major title back in 2015 and since then has added seven other PGA Tour titles to his resume, taking his career tally to 12. The Australian was runner-up in this event in 2016 and tied ninth 12 months ago, so he'll no doubt be confident of going well for the fourth year in a row.
Jordan Spieth (22/1)
Spieth's needs the US PGA title to join Gene Sarazen, Ben Hogan, Gary Player, Jack Nicklaus and Tiger Woods in achieving a career grand slam of majors. He won the last of his three major crowns at the 2017 Open Championship at Royal Birkdale, which was also his most recent trophy of any kind, and since then came very close at both this year's Masters (3rd) and a hard-fought Open at Carnoustie.
Justin Rose (22/1)
Rose became England's first major winner since Nick Faldo (1996) when triumphing in the 2013 US Open and could so easily have bagged a couple more having twice finished second in the Masters, tied second in this year's Open and fourth at the 2015 US PGA Championship. Rose won his ninth PGA Tour title at this year's Fort Worth Invitational, finishing three shots ahead of Brooks Koepka, while he also held off the young American star - as well as Dustin Johnson and Henrik Stenson - at last October's WGC-HSBC Champions to claim another impressive triumph.
Tiger Woods (25/1)
Tiger Woods won his 14th major at the 2008 US Open and it was just a matter of 'when' he would break Jack Nicklaus' record of 18. Ten years and four back operations later, Tiger (and an impatient army of fans around the world) is still waiting for his 15th but there are encouraging signs that it could yet happen. He was unable to convert a one-shot lead with eight holes remaining at this year's Open but at least he put himself in contention.
Francesco Molinari (28/1)
Molinari's tie for second in last year's US PGA went largely unnoticed despite a brilliant second round of 64, the Italian eventually finishing alongside Patrick Reed and Louis Oosthuizen, two shots behind Thomas. However, since missing the cut in May's Players Championship, Molinari's form figures read an amazing 1-2-25-1-2-1, the latter win in the Open making him the first Italian major champion.
Tony Finau (40/1)
Ask people to name the player with top 10 finishes in all three majors this season and not many would come up with Tony Finau, but the 28-year-old was 10th in the Masters despite injuring his ankle in the par-three contest, fifth in the US Open and ninth in the Open. A good performance could also secure a Ryder Cup debut.
