Jos Buttler turned 23 just last Sunday but recognises he has the experience to judge a run-chase when the pressure is on.
Buttler’s 48-ball 65 not out saw England reach 228 with three wickets and as many balls to spare at the SWALEC in the fourth one-day international.
That levelled the NatWest Series at 1-1 and ensured it will be decided in Monday’s finale at the Ageas Bowl.
The wicketkeeper-batsman came to the crease with the hosts 126 for five from 34 overs and Australia scenting series victory.
Buttler, in his 18th ODI today, said: "I've played enough cricket now to know when it's getting out of hand.
“It's just 'pick your bowlers, pick your moments' and hope it comes off in your favour.”
It certainly went in Buttler’s favour as he hit two sixes and five fours, one of each off Mitchell Johnson in the last over with seven needed to win.
Buttler and Ben Stokes added 75 for the seventh wicket to put England on the brink.
"We were always confident, as long as we were there at the end and took the game deep,” Buttler added.
"The run-rate wasn't too out of hand, and I knew if I was there at the end we wouldn't be very far away.”
England were up against it early on when Clint McKay’s hat-trick left them eight for three.
It was up to captain Eoin Morgan and opener Michael Carberry to restore the innings and they did just that with a 104-run stand, each making a fifty.
Morgan said: "Obviously, our backs were against the wall - and Michael and I just said pretty much 'we've got to bat time, and find a way to get through this tricky spell'.
"It's hugely satisfying. The guys can take a lot of confidence from this game, particularly the young guys coming through.”
Australia skipper Michael Clarke praised McKay, whose hat-trick consisted of Kevin Pietersen, Jonathan Trott and Joe Root.
"He's a huge part of our team, and he deserves this. It's a pretty good hat-trick to have - some good players in there,” he said.
Ultimately, though, even McKay’s 4-39 from 10 overs could not defend Australia’s 227 all out.
"We knew we had to take 10 wickets to win the game, and unfortunately we didn't do that,” he added.
