From Brooks Koepka in 2015 to Jon Rahm in 2016, our annual sleepers* selections have warranted some serious pats on the back the past few years. And while so many young players recently have had success on the PGA Tour, there’s still a crop of others waiting in the wings for their shot. Here’s our list of the most likely up-and-comers to emerge and join the likes of Koepka and Rahm as tour stars during the 2017-’18 campaign.(*We define a "sleeper" as a player who has never won on the PGA Tour or qualified for the Tour Championship. This year we also decided to only include players younger than 30.)
