Once the 2017-18 season is over, all attention will shift to the Ryder Cup. I played a practice round with (Mark Calcavecchia), and, you know the tragedies that happened transpired. "I had them both going this week", he said with a smile. "What can we do better?" recalled Thomas' father and swing coach, Mike. "You can go to really anywhere in the country in May and have an opportunity to play". It is effectively two tournaments in one - the final major of the year and one last chance to avoid having to audition as a captain's pick.
Bellerive has also hosted the inaugural Mid-Amateur Championship in 1981, the US Senior Open in 2004, the 2008 BMW Championship, the 2013 Senior PGA Championship and now the 100th PGA Championship.
Thomas talked about getting himself back into contention.
Thomas is methodical about goals, thumbing his annual wish list into his phone with surprising detail.
There will undoubtedly be more of that this week in steamy St. Louis, given that it is the final major of the year.
"That has been what we have stressed for two years". These guys are multitalented and can move it one way or another to get to where they need to go.
"Friday morning he was putting [before his round] and I thought he was going to go ballistic".
"I like the way the PGA sets it up", Koepka said.
"Where my game is, I feel like I've done as well as I could with what I have. If you're not stroking it well you can't control that, but you can control your attitude'". Dating to previous year at the PGA, Thomas has won five times.

Stokes punched him. "He had a conversation with his friend and he said "300 get us in" and I still told them no". "As the group came to my attention, I heard some of what was being said", Stokes said in the written statement.
Day's closest calls have come at the PGA Championship, finishing second by a shot to Jimmy Walker during his title defence in 2016, before sharing ninth behind victor Justin Thomas past year. "I've had my share of chances to win this year, as well, and hopefully I'll get it done this week". And then he missed the birdie putt, made a double bogey on the next hole and faded away. There will be rounds of 73 - just like Rory McIlroy, Rickie Fowler and Jason Day shot on Sunday. "It's a big deal, but I think, once you get out on the golf course and you start the tournament, all you're thinking about is trying to shoot good scores and hit good golf shots".
"It's a great position to be in", said McIlroy, who needs the Masters to complete his own Career Slam.
As he said after the final round at Carnoustie: "Given where I was to where I'm at now, blessed".
In an ominous sign to the 156-player field, McIlroy says Bellerive resembles Kentucky's Valhalla Golf Club, where the Northern Irishman put on a driving clinic in 2014 to claim his fourth major title.
The challenge at the oldest Major was followed by a lackluster performance at last week's World Golf Championship at Firestone, that suggested the 42-year-old still has some work to do if he is to finally get back into the winner's enclosure. For almost a half century, the hole played the highest to par in U.S. Open history. He was tied for the 36-hole lead and shot 74. 13 and 14 on his way to a closing 68 and a runner-up finish.
"I think we would all agree, or most of us would agree, that the face of this game has to change if it's going to grow". So just coming back and being able to play at this level and compete.
Some might call that patience, which he may not have fully embraced had he not used that rainy practice round to sort things out with his father and caddie Jimmy Johnson.
"It's definitely something that's a big accomplishment and something that I'm very proud of", Johnson said of the No. 1 ranking. "Justin said this is what I want you to do, Jimmy".
