"I've actually never thought about that; three majors at 28, it's a cool feeling", Koepka said after winning the PGA Championship on Sunday.
Stewart Cink felt as if he'd traveled back in time on Saturday, playing with Tiger Woods and all that entails - the massive crowds, the raucous cheering and the mind-bending intensity.
Looking to join Gene Sarazen, Ben Hogan, Jack Nicklaus and Woods as the only players to win the US Open and US PGA in the same season, Koepka had raced to the turn in 30 and briefly enjoyed a five-shot lead at Bellerive Country Club.
The 29-year-old was already on the 17th hole when the final pairing of Brooks Koepka and Adam Scott headed down the first, but most eyes were on Woods as he produced the flying start he needed in pursuit of a first major since 2008. He scrambled to make par, but by the time he reached the 18th fairway, he was three back of Koepka, who birdied 15 and 16 behind him.
For the third round in succession Woods looked set to bogey the hard par-four 10th hole, which plays as a par five for the members, when he could only hack out from heavy rough to the right of the fairway.
Following his oh-so-close sixth place at the Open last month, Tiger's second place yesterday was his best performance in a major championship since he was caught and passed by Y.E Yang at Hazeltine in the US PGA nine years ago.
"Tiger's coming", yelled one of the few spectators who bothered hanging around to watch Koepka and Scott after the 14-times major champion had been through.
"This is motivation to kick on, make the most of the rest of this year and go into next year's (majors) season full of confidence".
In the end, though, it was Koepka who held off the entire field and walked away with his second major title of the year.
Deadlocked for the lead with Scott - who began the back nine with three birdies in four holes - and only one stroke ahead of Woods, Koepka sank a 10-foot birdie putt at the par-4 15th and a six-foot birdie putt at the par-3 16th then parred the last two holes to secure the victory.
The 14-time major victor was sporting his traditional Sunday red with some shades on, but it was the addition of his cap being worn backwards which got fans on social media talking. He parred his first four holes, before bogeying the fifth. She was 5 up after 18 holes and increased the margin to seven on the second 18. It was Kern's first major appearance and the first event in which he has competed against Tour professionals. He was not a factor in any of the majors, though he was regarded as a central figure in the team room and helped reshaped the US model for the Ryder Cup.
You could see it in the throngs following and fixating on him, including Missouri Gov. Mike Parson, Olympic swimming icon Michael Phelps and a Missouri State Highway Patrol trooper who marveled that Woods seemed to have the status of a "demigod".
Cone earned $108,000 to jump from 135th to 37th on the money list with $131,580.
Tiger Woods did not win the PGA Championship and when he thinks back at what could have been, he will have nightmares about hole No. 11. In the women's final Persson and Wessberg topped France's Justine Dreher and Manon Molle in 20 holes.
Oriol and Fernandez beat Iceland's Birgir Hafthorsson and Axel Boasson 2 up in the final.
