|International fourth day, Trent Bridge, Nottingham|
|Pakistan 340-7 (50 overs): Babar 115, Hafeez 59, T Curran 4-75|
|United Kingdom 341-7 (49.3 more): Roy 114, Stokes 71 *, Vince 43|
|England won by three wickets; complete series wins with one to play|
England survived the fear of winning a fourth day international match against Pakistan with three wickets and ending the series with one match remaining.
Jason Roy's age made the home side chase 341, only because his dismissal triggered a four-wicket collapse for 15 runs.
But Ben Stokes made 71 no outs and Tom Curran, who should have run out of seven, 31 to get the hosts over the line with three balls left.
In conditions of perfect blows on the Trent Bridge ground where England have collected two of the highest total ODIs of all time, Pakistan recorded 340-7.
Babar Azam's 115 is still a mainstay, even with England losing the captain suspended Eoin Morgan and resting Jonny Bairstow's opener, the total the visitors don't feel like it should be a challenge.
That England were finally tested would only be good for preparing for their World Cup and winning with a team that changed a lot – Chris Woakes, David Willey and Liam Plunkett were also rested – further showing the depth of their squad.
England led 3-0 in the five-match series, which ended at Headingley on Sunday.
Stokes guides England home
England were under pressure in the second match of the series, when Pakistan almost overhauled 373 at Southampton, but they dominated the third match at Bristol.
As far as their World Cup buildup takes place, this is a new test because they recovered after stumbling in run-chase.
In addition, it is the return of the welcome to form Stokes, who struggled with bats and balls at the end of the IPL and has not taken the goal in this series.
With England needing 125 from 19.4 overs, Stokes first shared 42 with Joe Denly and then, most importantly, 61 with Curran, who previously claimed 4-75 with the ball.
There was a strange moment when Curran was supposed to run out, only so Pakistan would not appeal even though the Surrey man's bat was in the fold when the guarantee was revoked.
Both Stokes, who struck three points six, and Curran spiced up square boundaries, until Curran was fascinated by Hassan Ali in the 48th minute.
Adil Rashid joined Stokes with 19 needed from two finals, but 49th Junaid Khan was taken for 16 and Stokes won it from the third ball final.
Roy ton preceded the collapse of England
For a long time, it looks like Roy will lead Britain to a massive overhaul with impunity, just as the Bairstow century was a catalyst for a comfortable pursuit of 359 in Bristol on Tuesday.
With Bairstow resting, Roy added 94 with new opening partners James Vince and then 107 with Joe Root.
He was dropped on 25 by Fakhar Zaman, one of a number of early Pakistani errors on the field, and scored all goals around the goal – four of them almost became compass points.
After he reached the eighth ODI, a hundred out of 75 balls with extraordinary cover, even a century of doubles seemed possible, but when he gladly made Mohammad Hasnain's efforts, the fate of the two sides was reversed.
Root was caught in the short third by Mohammad Hafeez of Imad Wasim, standing captain Jos Buttler swept the same bowler for a good short leg for the two-ball duck and Moeen Ali carelessly misused Shoaib Malik into the middle goal.
The collapse made Pakistan a favorite, but that for discount Stokes could not be repaired.
Not enough for Pakistan
As the battle for bowling points in the England World Cup squad continues, a lot of intrigue surrounds the new Nottingham ball pair from Mark Wood and Jofra Archer, the fastest bowler in the host.
With both bowlers regularly touching 90mph, there is an extra dimension to the attack which, sometimes in this series, looks one step.
Indeed, Wood hit Pakistan's Imam-ul-Haq's opening elbow and forced him to retire. Then, he also shook the Imad Wasim helmet while Archer reflected the returning Imam.
Among them, Babar guided Pakistan with a calm century, adding 107 with Fakhar and 104 with Mohammad Hafeez, both of which produced half a century.
However, in a very good blow, there was still suspicion that the tourists did not have the intention to reach a total that would defeat England.
Not only that, but they are still being checked by the home team and Curran, who raised his own World Cup hopes with a slower yorker and ball even before his efforts with bats.
& # 39; Run out perfectly for England & # 39; – analysis
Former England captain Michael Vaughan: "This game is almost a perfect scenario for England: to be under this pressure with their all-key lock not coming out in the end because it's not in good shape.
"Ben Stokes – he hasn't played well – needs time in the middle, in a tight situation, where the balance has swung into Pakistan to win and he brought England home with a good strike.
"Pakistan is not far away. They got three good scores.
"If their field can reach a reasonable standard – some of those mistakes aren't even amateur – I've seen enough that they will threaten many teams in the World Cup."
"Bowlers succeed brilliantly … 340 isn't a big score & # 39;
British Captain Jos Buttler at TMS: "It was a very good victory. For the most part our match was very good.
"We have a very bad partner with a bat that is disappointing but for Ben Stokes to be there ultimately having a great partnership with Tom Curran is good for us.
"I think the bowler performed brilliantly today. 340, as dumb as it sounds, a little below what we can pursue after Pakistan started with a good start. We have seen the score getting higher and higher. 340 is not a big score to catch up today.
"I t [final World Cup squad] is a very difficult decision for people to make but what's great for us is the people who stand up. Tom Curran has a fantastic day today. "
