Skipper Tim Paine hailed the display of Australia's unheralded bowling attack after they almost pulled off a stunning one-day international win over England at The Oval.
With Ashes winners Pat Cummins, Josh Hazlewood and Mitchell Starc sidelined with injuries, rookies Billy Stanlake, AJ Tye, Michael Neser and Kane Richardson were tasked with the job of defending an under-par total of 214 for victory on Wednesday.
Despite having less than 25 caps between them, the quartet reduced the world's No.1-ranked ODI side to 7-197 to close in on an unlikely victory before David Willey's unbeaten 35 helped England over the line with six overs to spare.
The display of Queensland quick Stanlake (2-44), who beat Jason Roy for pace with the second ball of the innings to re-arrange his stumps, was a positive sign in defeat.
There were also promising displays from debutant Neser and wily medium-pacer Tye, who took two wickets apiece.
Stanlake, who stands at 2.08m, also dismissed Joe Root for 50, excellently demonstrating the depth of Australia's fast bowling stocks.
"That attack is really exciting," Paine said.
"I've said before in the lead-up that they are inexperienced at international level but they have played a lot of Big Bash.
"All the bowlers we have got here have a lot of different skills and variation in their bowling.
"We are really confident that if we get enough runs they will create enough chances for us to win games of cricket. I thought they were all really good today."
On Thursday, Australia head to Cardiff for Saturday's second ODI looking to end their poor run against England in which they have lost six of the last seven matches to Eoin Morgan's side.
