After being sent in to bat by England captain Eoin Morgan, the home side posted 304 for eight from their 50 overs.
Root was hospitalised on the final morning of the Ashes in Sydney having been stricken with a bad case of gastroenteritis and sat out Thursday's warm-up match against a Cricket Australia XI.
England batsman Joe Root is fit to play in Sunday's first one-day worldwide against Australia in Melbourne after recovering from a viral illness. "He's been a fantastic leader within the group and, on top of that, there's the weight of runs he's scored and the manner that he's scored them".
"He is obviously a key part".
Jason Roy blasted the highest score at the MCG to help England to victory in the opening one-dayer against Australia
"He's a versatile player who can score in any strike-rate that is required", he said.
While Root's participation is all but assured, Australia captain Steve Smith stopped short of confirming that David Warner's involvement after the opener's struggles with a stomach bug over the past two days. "He turned up and walked the oval a few times, but he said he'll be fine so I don't think there'll be any trouble".
When Morgan was asked if he saw separate coaches being employed beyond 2019 when Trevor Bayliss' contract expires he said: "I think down the line there will be.Cricket is going to change even more in the next 10 years than it has in the previous 10 years".
Since Australia's World Cup final win at the MCG in 2015, the left-hander has averaged more than 80 from 11 games in Australia, including five centuries.
The Ashes is done and dusted but the rivalry between traditional foes Australia and England resumes in the 50-over format in a battle expected to be far more exciting and closely fought than the disappointingly lop-sided Test series.
They have a better record than any other team since the last World Cup winning 34 of 53 matches.
