Not this one. His 12-under after 54 holes is second only to the 14-under Rory McIlroy posted at Congressional in 2011.
Unheralded American Brian Harman leads the field by one shot on 12 under, and will tee off in the final pairing alongside Justin Thomas at 2.54pm local time (1954 GMT). Koepka birdied his first two holes and made five on the day against just one bogey in a closing 4-under 68.
The resulting birdie reduced his deficit to playing partner Koepka to four shots, Koepka having followed birdies on the first and second with another from 35 feet on the eighth.
Japan's Hideki Matsuyama was battling his way into contention going four-under through 13 holes to sit four off the pace alongside Englishman Tommy Fleetwood. But for whoever finishes as the U.S. Open victor, life will get a little richer.
Erin Hills played easier yesterday for a variety of reasons, but that doesn't mean it played easily. Thomas capped off his record day on the 667-yard 18th hole at Erin Hills with the prettiest 3-wood he ever hit, stopping 8 feet away on a green where some players struggled to land a wedge. The 21-year-old South Korean became the youngest Players Championship victor in history last month.
Jordan Spieth finishes US Open on a high note
Sharing fifth were Americans Xander Schauffele (69), Bill Haas (69) and Rickie Fowler (72) at 10-under. Despite rallying back with two closing birdies, a bogey at the 18th sealed 30-year-old Harman's fate.
The American Ryder Cup star then bagged a trio of birdies on the 14th, 15th and 16th holes to finish at eight under.
But Miller hinted that his round was superior and hit out at the "soft" course set-up in Wisconsin, suggesting it felt more like a regular PGA Tour event than a typical US Open.
"I'll get some sleep and then come out and make a plan", he said. We had 0.9 inches of rain last night, and it turned Erin Hills into a dart board.
Stricker shot a 69 to move to 2 under going into the final round.
Jordan Spieth, the 2015 US Open victor, shot a 69 to claw back to one-over. Of all his birdies, that 8-foot par putt might have been as big as any. The final-round average was 77.2, and 20 players shot in the 80s.
FILE - In this June 22, 2009, file photo, Ricky Barnes keeps on eye on his chip to the fifth green during the final round of the U.S. Open golf tournament at Bethpage State Park's Black Course in Farmingdale, N.Y. Barnes had a six-shot lead at the turn until he hit only three fairways on the nine and missed a 4-foot par putt on the 18th for a 70. Even though it will be hard, I don't anticipate this being a blood-letting. "It means I have a lot better chance to win the tournament than I did when the day started", said Thomas after becoming the 29th player to shoot 63 in a major championship. Seven players already have reached 10 under or better this week - Koepka, Harman, Thomas, Fleetwood, Fowler, Charley Hoffman and Matsuyama.
Of the 24 players on the course early, only two are under par for the day - William McGirt and Jordan Spieth.
