England posted a massive record-breaking total of 481- 6, courtesy centuries by Jonny Bairstow (139 runs) and Alex Hales (147) as they thrashed Australia by 242 runs to clinch the series with two games to spare.
Bairstow struck three fours off quickie Jhye Richardson's first over and Roy tucked into Billy Stanlake, pulling him for a six as England reached 38-0 after five overs.
Bairstow, on 30, skyed a drive off Tye but Marcus Stoinis failed to hold an extremely tough chance as he ran back from mid-on. Surrey had hammered the gargantuan total against Gloucestershire at The Oval during the 2007 Friends Provident Trophy.
It was his fourth in his last six ODI innings - and although he was eventually caught at deep midwicket off Ashton Agar, having hit 15 fours and five sixes, number three Hales simply took over to the delight of his home crowd. The pitch is unlikely to allow the sort of free-scoring that England managed in Nottingham and the highest score in the Royal London One-Day Cup at the Riverside was 299.
It wasn't just Australian wickets that tumbled at Trent Bridge yesterday - so did one-day records as England obliterated their old foe in sensational style.
England bowled out Australia for 239. But he was back to his best at his home ground in Nottingham and reached three figures even quicker than Bairstow, his seventh worldwide ton coming off 62 balls.

However, their attempt to create history got off the worst possible start as they feel to a shock opening game defeat to Mexico . Spain, in 2010, are the only side to win the World Cup after losing their opening match, when they were beaten by Switzerland .
After winning the toss and putting the hosts in to bat, the Australia was bowled out for 239 to slump to its biggest ever defeat - usurping a 206-run loss to New Zealand in Adelaide 32 years ago.
"Just woke up and saw the score in England". "It's a case of following and watching the ball".
Here are all the numbers from England's imposing batting performance in the third ODI of the 5-match series.
England's Eoin Morgan and Alex Hales congratulate each other after passing previous highest total of 444 runs.
The opening stand fetched 159 runs inside 20 overs and was broken with Roy's run out in his attempt to scamper for the second run. Off-spinner Moeen Ali took 3/28.
"Sometimes you've just got to accept what you've got and be ultra-defensive from the start, put a few more fielders in front of the batsman's face and see if you can create a bit of pressure that way".
