Finch was soon into his stride with a pulled four off express fast bowler Jofra Archer - playing his first white-ball global since bowling the decisive Super Over in England's 50-over World Cup final win over New Zealand at Lord's past year.
A target off 19 of 12 balls proved too much for the likes of Marcus Stoinis in his first worldwide match since last year's 50-over World Cup semi-final defeat by eventual champions England.
England might look to push Tom Banton back up the order to make use his of fearless style of play, but it is the question marks on the middle order that could hold them back.

Australia were in pole position to win the first game after a cracking start to the chase by their openers, but Maxwell who has been among their best bets in the middle order struggled.
David Warner said it felt "bizarre" to be playing England without a crowd following Australia's two-run defeat by their arch-rivals in a Twenty20 worldwide at Southampton on Friday that marked the tourists' first competitive match in almost six months. So we like playing at home and on the other team's ground.
"Someone like M. S. Dhoni, he was one of the best in the world because he played 3-400 ODI games. T20 is not that easy to be consistent because at times you have to go in and give it a bit of a smack, he has been incredibly consistent", Hussain told "Sky Sports". We know it's not going to happen overnight. "We got us off to a good start and neither of us really kicked on". "Doesn't matter what it is, we'll be desperate to beat them".
Cummins also tried to put the result in context by saying defeat, while "disappointing", was not as painful as losing an Ashes Test. With the COVID-19 pandemic spread all across the globe, stadiums have now resumed matches without the crowds.More news: Activists step up Mulan boycott campaign
But the required run-rate ballooned and he wanted 15 runs off the final over, delivered by Tom Curran, to win. We are really grateful for the opportunity.
Meanwhile Finch said either he or Warner should have seen Australia home. Then again, that's nothing new particularly for the English, who have managed to fit in a full global summer of cricket in all formats against the West Indies, Ireland and Pakistan despite the pandemic.
"I don't think it bothers them". "It is certainly different being over here in England and not hearing some of the songs".More news: Deshaun Watson signing monster extension with Houston
