And it still felt like he was the second billing to Tiger Woods.
But the defending champ wouldn't circle another hole on his back nine.
On Sunday (Monday NZT), it wouldn't budge.
The big-hitting American fired a four-under-par 66 at Missouri's Bellerive Country Club to earn a 16-under total and a two-shot victory from 14-time major victor Tiger Woods (64), with Australian Adam Scott (67) third at 13 under.

No shots were more important than a four-hole stretch he played in 2 over that turned Sunday into what could be a free-for-all. When Tiger started making his little run, and then Scotty (Adam Scott) made his run, it got quite loud. His entire lead evaporated as Justin Thomas tied him at the top.
Woods had made the ideal start by holing from 15 feet for birdie on the first and five feet for another on the second, before nearly chipping in on the fourth after finding trouble off the tee.
When people mocked Erin Hills as an unworthy U.S. Open test, Koepka answered them two months ago by acing what the USGA conceded was an unfair test at Shinnecock Hills, and he became the sport's first back-to-back national champ since Curtis Strange three decades earlier.
