Australia have spluttered to 174 all out in game two of their T20 series with New Zealand, losing 4-18 in four overs to give the Black Caps a mighty chance of levelling the series.
Sent in by Kiwi skipper Mitchell Santner, Australia roared to 2-103 off eight overs in Auckland on Friday night and looked like setting a monster score.
From that point they collapsed, with Travis Head (45 off 22) the only bat to play with any conviction and the returning Steve Smith among the failures.
Smith was one of three changes to the Australia team, with Nathan Ellis and Matthew Wade also coming in for David Warner, Mitchell Starc and Matt Short.
Mitch Marsh's side were too often tempted by the tonk given Eden Park's short boundaries, with four of the top six bats caught attempting to slog.
The condensed ground paid off for Australia early, with Head top-edging two Trent Boult deliveries for six as the returning speedster went for 20 in his first over.
Smith fell lbw to Lockie Ferguson - who had a blinder with 4-12 off 3.5 overs - in a blow for his hopes of making Australia's T20 World Cup side.
The 34-year-old great doesn't have an Indian Premier League contract, with coach Andrew McDonald admitting how he performed in Auckland would "dictate what happens" with his World Cup place.
However, there were few that did much better on Friday.

Australia didn't string together a partnership of note after Head's departure, who chopped on from impressive paceman Ben Sears (2-29 off four).
Glenn Maxwell (six off four balls) found Boult at long on, and two balls later, Marsh (26 off 21) - who should have been caught twice in the field - did the same two balls later.
Josh Inglis and Matthew Wade fell cheaply in the next two overs, while finisher Tim David wasn't able to make it to the death for a fifth straight T20I, falling in the 15th over to expose the bowlers to the Kiwi attack.
Pat Cummins (28 off 22) batted smartly before holing out in the 19th over, the tail offering no resistance after his departure.
New Zealand's turnaround was all the more impressive given they lost wicketkeeper Devon Conway in the second over.
Conway misread an Adam Milne delivery which struck him on the thumb, causing a delay before the gloves were thrown to Finn Allen.
Australia lead the series 1-0 after David's last-ball boundary in Wellington on Wednesday, and can retain the Chappell-Hadlee Trophy with an impressive bowling effort.
Failing that, game three is at the same venue on Sunday.
