Jason Roy simply played the innings of his life here.
Opener Jason Roy smashed England's highest individual score in one-day internationals to guide his side to a comfortable five-wicket victory against Australia in the opening match of the series in Melbourne.
The dynamic all-rounder has been in excellent touch in domestic cricket and his absence is likely to remain a talking point if England maintain the upper hand in the series.
Roy's blistering innings, during which he was supported by Test captain Joe Root who finished unbeaten on 91, halted Australia's domination of England and went a small way to easing the pain of their Ashes humbling.
And it was compelling evidence as to why England have always wanted him in their one-day team; why they only dropped him with the greatest reluctance in last year's Champions Trophy semi-final and why they welcomed him back eagerly at the end of last summer when Hales...
Roy surpassed Alex Hales' previous mark of 171 before the opener was caught late on as England eased to the highest successful run chase at Melbourne.
The Australian skipper noted that England had a wealth of attacking options with Roy, Jonny Bairstow, Alex Hales, Eoin Morgan and Jos Buttler all inclined to bat aggressively.
The second ODI will be played in Brisbane on Friday. It had been a tough season last season, so to be selected was incredibly special.
Finch's 107 was backed by half-centuries for Mitchell Marsh (50) and Marcus Stoinis (60) as Australia recovered from a shaky start in which the tourists finally managed to get bogeyman Steve Smith cheaply.
"I thought it was incredible from Jason - when he scores runs he's quite imposing at the crease".
"I've got 50 overs to bat and if I bat 50 overs on good pitches in Australia I'm going to get to a good score, and that was my mentality".
"I guess if you do that, perhaps you're going to have days where you get bowled out for not many but you back your players to come off maybe more often than not and get those big totals", Smith said. "I've heard it's a pretty nice track, so [I'll be playing]", he added.
"We will have to come up with some plans in the next game".
"What a way to start the series".
He said: "It's important not to look too far ahead, but it's a good opportunity for us young guys coming in to cement our places in the one-day team". "We need to start playing better cricket and get a few wins in this format".
