Eight of the last nine British Open champions have been first-time winners.
The favourite heading into Thursday's opening day of the 147th Open is world No. 1 Dustin Johnson, who has never golf's oldest major, per OddsShark.
Nor have Justin Rose, Rickie Fowler, John Rahm and Tommy Fleetwood, who are also well fancied.
Many will look to the group of favourites to produce the 2018 champion at Carnoustie in Angus, Scotland.
But there are plenty of sleepers who could also make a splash.
Paul Casey 40-1
Casey, 40, will play in his 16th Open Championship this year at Carnoustie.
