The perfect day and the worst day. Rarely have emotions been so polarised than with England and Australia at Trent Bridge. The teams have less than 48 hours to reset themselves before starting again at Chester-le-Street with two distinct aims: a push for a whitewash for England and a face-saving exercise for Australia.
There was talk of a whitewash the last time these teams met, in Australia earlier this year, but England's ambitions on that occasion we scuppered by one of their eye-watering collapses when they slumped to 8 for 5 in Adelaide. That, perhaps, remains Australia's best chance of taking something this time - that England have a day when they nick a lot rather than middle shots into the stands - although the bowlers took such a hammering at Trent Bridge that it will be tough to recover.
It is a mark of the expectations around this England team that holes were picked in the first two performances of this series and it is rare for Eoin Morgan to sound as satisfied with an outing as he did in Nottingham - although if he wasn't happy then, he may never be. Still, the perfect day in a bilateral one-day series against a poor team is one thing. England will want to save a few for this time next year.
After a perfect display, perhaps the one thing England would like is a few more wickets with the new ball. Mark Wood has taken two scalps in three matches with Australia, by and large, not having too many alarms against his new-ball spells only to repeatedly stumble when spin is introduced. That's working fine for England now, but if they can make impact with the new ball - which highlights the significance of Chris Woakes' absence - they become even more formidable. And there's a daunting thought.

In the spotlight
Joe Root isn't a slogger. He almost managed a wry smile when he walked out at No. 7 at Trent Bridge. It will have been one of the least-pressurised situations he will ever have batted - and he barely middled one shot. His fifty in the opening match, when England had lost three early wickets, showed how important his role in the side remains. He purred to a half-century at The Oval and eased into the 20s at Cardiff, but after the pyrotechnics in Nottingham he has had the quietest series of the top order.
Tim Paine admitted he hadn't had a worse day on the cricket field in his life than Trent Bridge. He's a good man in a difficult position. His captaincy of the one-day team is even more of a sticking plaster than with the Test side, where he at least justifies his position. It's hard to say the same in this side. You could even suggest he isn't the best option in this squad: Alex Carey is a talented, dynamic keeper-batsman. If Australia are serious about reviving their one-day team, Paine does not look the answer. He may have just two more matches to make a case.
England have bolstered their pace attack by calling up Craig Overton and Sam Curran. Morgan hinted at the potential for changes due to the lengthy journey from Nottingham to Durham and the short turnaround between games. Tom Curran and Jake Ball were already part of the squad, so may get first dibs.
England (probable) 1 Jason Roy, 2 Jonny Bairstow, 3 Alex Hales, 4 Joe Root, 5 Eoin Morgan (capt), 6 Jos Buttler (wk), 7 Moeen Ali, 8 David Willey, 9 Liam Plunkett/Jake Ball, 10 Adil Rashid, 11 Mark Wood/Tom Curran
What can Australia do? Shuffling deckchairs on the Titanic springs to mind. Justin Langer has suggested Nathan Lyon could get a call-up, although that may create issues with the tail. Andrew Tye may need to be benched after a tough couple of games. Aaron Finch's move to No. 5 hasn't worked, either.
Australia (probable) 1 D'Arcy Short, 2 Travis Head, 3 Shaun Marsh, 4 Marcus Stoinis, 5 Aaron Finch, 6 Glenn Maxwell, 7 Tim Paine (capt & wk), 8 Ashton Agar, 9 Jhye Richardson, 10 Kane Richardson, 11 Billy Stanlake.
Pitch and conditions
Chester-le-Street can offer more help to the pacemen than some grounds around the country, although the Royal London Cup did feature scores over 300. The forecast is set fair for the day-night game and the match is a sellout, an important boost for a county that has had well-documented struggles of late.
Stats and trivia
This is the first ODI at Chester-le-Street since 2015 - when England beat New Zealand in the decider to take the series 3-2
Jonny Bairstow's four centuries in 2018 already equals the most by an England batsman in a calendar year (David Gower in 1983)
Andrew Tye's series economy rate of 7.96 is the highest for an Australia bowler to have delivered at least 20 overs in a series
"Their top three are brutal. The way they are playing is reminiscent of how we used to play in our day with Gilly, Matthew Hayden and Ricky Ponting at the top."
Justin Langer lauds England's top order
"We've always looked at series like this, and games with one day in between, as quite rigorous for the bowlers. Their risk of injury goes through the roof. So we'll have to see how they pull up, and what they can do."
