Here's an at-a-glance guide to Ben Coley's Open Championship portfolio, with selections ranging from 5/6 to 300/1.
Patrick Cantlay - top-10 in the world now and arguably the sport's most complete player; nothing wrong with 12th at Carnoustie on Open debut last year, a winner since and has played well in every major this year.
Henrik Stenson - convincing winner in 2016 when out-duelling Phil Mickelson, and has been a consistent Open contender over the last decade. Rounding into form with long-game under total control and will relish the grind.
Tommy Fleetwood - solid in each of the last two renewals albeit his best major form has come in the US Open. Arrives a little under the radar this time, which will suit, and has the all-round game which will be required.
Shane Lowry - broke through on an Irish links as an amateur a decade ago, and has since competed at the very highest level. Has an Open top-10 finish, is back in form courtesy of an early-season win, and magic hands will take him a long way.
Jazz Janewattananond - spectacular form throughout the first seven months of the year, including when second through 54 holes of the PGA. Close to world's top 50 now and by far the pick of the outsiders.
Christiaan Bezuidenhout to be top South African - recent winner in Spain who has some links form and an interesting score to settle at Portrush. Louis Oosthuizen to beat but is capable.
Adam Hadwin to be top Canadian - considered the banker of the tournament at 5/6 with just two to beat. One of those is without a top-10 finish in two years and the other has struggled since winning. Hadwin the form and class pick.
Brian Harman to be top left-hander - all about the vulnerability of the favourites, this. Phil Mickelson is hopelessly out of form and Bubba Watson struggles in the Open. That makes Harman the value play and he's in good form.
Byeong Hun An to finish in the top 20 - this Korean is a huge talent who flushes it and can contend anywhere if the putter behaves. Three top-20 finishes in his last four starts and did well in the Open five years ago.
Jim Furyk to finish in the top 20 - aged 49 now but that's no barrier to success in the Open, and his approach play and overall form make him a contender. Not far off at Pebble Beach and this may be more suitable.
Justin Thomas to lead after round one - no great shakes in the Open so far, but determined to figure it out and his preparation has been ideal. Plus, he's never been worse than eighth after round one in this.
Rafa Cabrera Bello to lead after round one - couple of fast starts in the Open and this talented Spaniard arrives following a trio of top-10 finishes. Second at the course in 2012 and says he loves it.
Chez Reavie to lead after round one - career-best form last month, winning the Travelers after third place at the US Open. All of this has come courtesy of fast starts - he's fourth in first-round scoring in 2019.
Romain Langasque to lead after round one - in-form Frenchman who is purring over the state of his game. Winner of the Amateur Championship in 2015, he knows how to play links golf and can go well.
Zander Lombard to lead after round one - runner-up in the Amateur Championship here, the halfway leader in Ireland a fortnight ago, and an explosive talent capable of a low number.
