In fact, it held up for less than an hour with American Jamie Lovelock peeling off five consecutive birdies on the back nine in a record six-under 65 to claw his way back to even.
Not that Scott would have been too fussed.
"Yesterday, I got off to a bad start and, in the wind, it was tricky and I didn't scramble when I had to early in the round and it was slipping away from me," he said.
"Today, it didn't start much better - I was scrambling - but I scrambled well and then, all of sudden, I made eagle at 14 and momentum is on your side."
Scott finished his round in a share of third with Rod Pampling (67), former champion Robert Allenby (69), youngster Jake Higginbottom (69).
World No1 Rory McIlroy remained in contention, one shot behind the leader after shooting a 69.
Jordan Spieth had four bogeys and three birdies in his 72 to have all but one of his seven-stroke first-round advantage over Scott wiped out.
The American drawcard was annoyed at taking bogey on the par-3 fourth after a marshall trod on his ball and he was forced to take a drop.
But he hit back with birdies on his final two holes to claim a share of the clubhouse lead with Aron Price.
Players were wearing black ribbons during the second round to honour cricketer Phillip Hughes.
Championship director Trevor Herden said it was a sign of solidarity in the sporting community as Australia mourned the loss of one of its top professional sportsmen.
"We feel it's the right thing to do to show our tournament and the players are right behind the Hughes family and the cricket community," Herden said.
