True to his word, Adam Scott has hung tough to storm right into contention as a raft of golfing heavyweights floundered during the US Open second round at the beastly Oakmont Country Club.
While defending champion Bryson DeChambeau led the exodus of big names to miss the halfway cut, Scott carved out a second straight even-par round of 70 to be tied fourth in the clubhouse.
Contesting his 96th consecutive major, the 44-year-old showed the younger stars how to play major championship golf, repeatedly rebounding from bogeys with birdies to sit just three shots off the pace at the halfway mark of the tournament.
With the final pairs left on the course, play was suspended due to dangerous weather in the area. However most of those remaining are either safely inside the cut of 7-over or well outside.
Four Australians will be there for the weekend — Scott, Jason Day, Marc Leishman and Cam Davis. Cameron Smith made a late comeback on his second nine, but left himself too much to do and finished a shot outside the cut on 8-over. Min Woo Lee shot a 2-over 72 to finish on 9-over.
Sam Burns fired the low round of the championship, a brilliant 5-under 65 to snare the clubhouse lead at 3-under.
Fellow American and first-round leader JJ Spaun is second, one stroke behind Burns, after following up his starting 66 with a 72 on Friday (Saturday AEST).
Seeking his maiden major, Norwegian super talent Viktor Hovland is the only other player above Scott on the leaderboard, and one of only three players in red numbers at one under after posting a second-round 70.
Scott's fellow former world number one Day battled back into the picture with the second-lowest round of the day to also raise hopes of a famous Australian triumph at the US Open's most gruelling venue.
The former PGA champ was way off the pace after his opening round of 76 but demonstrated his enduring class with a 3-under 67 to get back to 3-over for the tournament, just six shots back entering the weekend in a tie for 13th.
Day's round, which began at the 10th hole, was ignited by a terrific eagle at his third hole — the gigantic par-five 12th that measures 647 yards.
He struck his approach from 323 yards to 20 feet from the hole and sank the eagle putt. Two birdies quickly followed in the next five holes.
His biggest disappointment as he looked set to finish with a 66 after two more birdies on the homeward nine, was his wayward drive at the ninth that led to an anti-climactic final bogey.
Burns, who shot a final-round 62 on Sunday at the Canadian Open before losing in a play-off, also started his second round on the back nine and birdied 11, 13, 17 and 18.
He responded to his lone bogey at the first hole by putting his approach at the next hole to about six feet.
American world number one Scottie Scheffler had five bogeys and four birdies in his 71 to be left at 4-over, alongside countryman Collin Morikawa (71) and fellow dual major winner Jon Rahm, who exploded after shooting a 75.
The second-round spoiler left the superstar Spaniard seven shots adrift of Burns.
"Honestly, I'm too annoyed and too mad right now to think about any perspective," Rahm said.
"Very few rounds of golf I played in my life where I think I hit good putts and they didn't sniff the hole, so it's frustrating."
Masters champion Rory McIlroy birdied the last hole in a round of 72 to be 6-over and just inside the cut line.
Australian Marc Leishman, who had begun promisingly with a 71, suffered in his second round with a 75 that included a double-bogey six at the ninth hole to also hover at 6-over.
A day after Patrick Reed recorded the fourth albatross in US Open annals, Frenchman Victor Perez made a hole-in-one at the par-three sixth, the second ever ace during a US Open at Oakmont.
Five-time major winner Brooks Koepka, one of 14 LIV Golf players in the field, started his day two shots off the pace but dropped back after a 74 that featured eight bogeys.
After out-duelling McIlroy down the stretch to reign last year at Pinehurst, DeChambeau won't feature on the weekend after slumping to 10-over with a second-round 77.
At nine over following rounds of 77 and 72, Australian Min Woo Lee was also sent packing, along with dual major winner Justin Thomas, 2016 Oakmont champion Dustin Johnson, fellow former world number one Justin Rose, LIV Golf dominator Joaquin Niemann and Swedish sensation Ludvig Aberg.
Incredibly, Johnson and Niemann were among some 60 players to finish at 10-over or worse, with American George Duangmanee racking up a +35 total with horror rounds of 86 and 89.
