Check out the major form ahead of this week's tournament at Bellerive. Stats compiled by Andy Swales ...
"Tony Finau tees-up at Bellerive as the only golfer this season to have posted top-10 finishes in all three major championships."
Francesco Molinari's well-deserved victory at Carnoustie last month ended a run of five straight major successes by 20-something Americans.
Victories by Brooks Koepka, Jordan Spieth, Justin Thomas and Patrick Reed seemed to suggest a changing of the guard in the men's game, as they scooped up the biggest titles in golf.
Molinari's timely intervention in Scotland was a welcome boost for European golf, with the Ryder Cup less than two months away.
However, with 10 of the last 15 major championships going the way of the US, the hosts will be keen to maintain their recent dominance.
Among the current crop of 20-something Americans looking in good shape to move into the major arena is Patrick Cantlay.
The 26-year-old from California has only contested four majors as a professional, but did manage a top-dozen finish in Scotland a few weeks ago.
Cantlay tied-sixth in Ohio on Sunday, so can certainly mix it with the big boys, and during the 2017/18 PGA Tour season has weighed-in with five top-10s - including a maiden title in Las Vegas.
Xander Schauffele is another American 'youngster' who has looked at ease in the big events, having finished inside the top six in each of the last two majors.
Over the years the PGA has usually been viewed as the major most likely to crown a first-time winner.
Seven of the last nine champions tasted major glory for the first time and, between 1988 and 1998, only one winner of the PGA had previously won a major.
Also seeking a first major title is Tony Finau. The 28-year-old tees-up at Bellerive as the only golfer this season to have had top-10 finishes in all three major championships.
His consistency is generally excellent, and he arrives at the PGA without any great expectations on his shoulders.
Four-time major winner Rory McIlroy could make history this week if he were to hold aloft the Wanamaker Trophy for a third time.
The 29-year-old, who won the PGA Championship in 2012 and 2014, would become the first non-American to collect the trophy on three occasions, moving ahead of Gary Player, Nick Price and Vijay Singh who all triumphed twice.
And a win for the Northern Irishman would also mean that only Walter Hagen, Jack Nicklaus and Tiger Woods would have won this particular major more times than him.
McIlroy's frustrating season continued last week when he began the final round of the WGC Bridgestone Invitational in second place, only to post a closing 73.
But he's certainly playing well enough to make that step up in Missouri and, during the past five months, his PGA Tour record reads: 12 Starts; 1 Win; 3 Top-Threes; 6 Top-Tens.
Jordan Spieth could also reach a personal milestone on Sunday by completing the full set of major titles - having already landed The Masters (2015), US Open (2015) and The Open (2017).
And, at the age of 25, he would become the second youngest to achieve this feat after Tiger Woods.
Despite experiencing his poorest season as a professional in 2018, Spieth still managed to contend at Augusta and Carnoustie, and can never be ruled out.
