Australia captain Steve Smith hopes his bowlers learn from their team's loss to South Africa in the third one-day international.
David Warner (117) and Smith (108) had put Australia in a strong position as they posted 371-6, a record ODI total at Kingsmead, Durban.
But an unbeaten 118 off 79 balls by David Miller saw the hosts reach their target with four balls remaining for a four-wicket victory and series win.
"It's a very tough loss," Smith told a news conference after Wednesday's defeat.
"Today was our quarter-final, I guess, to keep us in the series, and when you get to halfway and you've got 370 on the board, you don't lose too many games with 370 on the board.
"Our inexperienced bowling attack, it's a good learning curve for them, hopefully they can learn something out of that, but it's a tough loss."
Daniel Worrall (0-78), Chris Tremain (1-65) and Adam Zampa (1-55) in particular struggled for Australia.
After his side fell 3-0 behind in the five-match series, Smith tried to find positives - while he also lauded Miller.
"It's a pretty hard pill to swallow. We come off at halfway and 370 I thought was a pretty good total on that wicket, I think it was a record score at this ground," he said.
"I said at the start of the day, at the toss, that I wanted the top four to get the bulk of the runs, someone to go on and get 100, and we had two blokes do that so that's a positive.
"From there, I guess, we've just had South Africa getting off to good starts every time with the bat.
"Today we were able to take a few wickets in the middle and slow the flow of runs, and then obviously David Miller played a phenomenal innings at the back end there.
"He's a clean striker of the ball and on his day he's as dangerous as anyone so he took the game away from us at the back end there."
