Australian paceman Josh Hazlewood says he's surprised at how rapidly England folded in the second Ashes Test.
The tourists started Wednesday's final day of play in Adelaide at 4-176, needing 178 to win.
But after Hazlewood struck twice within the initial three overs, England stumbled to be bowled out for 224 as Australia took a 2-0 lead in the five-Test series.
"We didn't expect England to collapse," Hazlewood told ABC radio.
"We expected them to dig in and fight hard for every run."
Hazlewood's initial two strikes included the prized scalp of English skipper Joe Root.
"It was very pleasing that Josh was able to come out and do what he did," Australian captain Steve Smith said.
"His length was exceptional and to get the wicket of Root really put us in a good position and I could breathe a little more easily then."
Smith said Hazlewood was previously struggling to find his peak form.
"Josh probably hasn't been bowling as well as I've seen him bowl, I think he knows that," Smith said.
