New South Wales shut the door on Queensland with 20 minutes still to play in a famous Origin thrashing in Perth.
Josh Addo-Carr's 57th minute try made it five tries to one for the Blues and took NSW's lead out to 32-6.
The Blues again found a hole in the Maroons' right edge defence when Wade Graham put a neat kick into the in-goal.
Addo-Carr then won the race to dive on the loose ball.
The try completed 20 minutes of total domination from the Blues.
"It is officially a smash up," Maroons legend Paul Vautin said.
"They are running riot in the second half on the back of six penalties, all legitimate penalties. Field position. And the amount of ball they have had. They are just giving it to them."
Addo-Carr made it a double in the final 10 minutes when Damien Cook again orchestrated a line-break down the Maroons' struggling right edge defence.
Cook identified an overlap down the right side where the Maroons were caught two defenders short. He then got on the outside of Daly Cherry-Evans before the Blues passed it through a series of hands out to Addo-Carr on the wing.
It took NSW to a thumping 38-6 lead, the second biggest Blues margin ever seen in State of Origin.
