Umar Gul recorded career best one-day international figures as Pakistan fought back to clinch victory in the third ODI at The Oval, keeping the series with England alive.
Gul finished with 6-42 from his ten overs as England were bowled out for 218, the hosts coming up 23 runs short of their target after Pakistan had earlier been dismissed for 241 - Fawab Alam top-scoring with 64.
It means the five-match series is now delicately poised with England leading 2-1 ahead of Monday's fourth encounter at Lord's.
Friday's contest at The Oval turned on the dismissal of Eoin Morgan with the left-hander seemingly guiding England to victory as he shared in a record sixth-wicket stand of 98 with Luke Wright.
At that stage England were 201-5, but once Gul had claimed Morgan's scalp for 61, England's lower order crumbled with Luke Wright eventually left stranded on 48 not out.
Having won the toss, Pakistan opted to bat first on what appeared a typically true and batsman-friendly Oval track.
However, their openers Mohammad Hafeez and Kamran Akmal - who put on a century stand in the defeat at Headingley - did not find that to be the case as both departed within the first three overs to leave the tourists wobbling at 8-2.
Hafeez was first to go as he got the thinnest of edges behind to a beauty from James Anderson which pitched and left the right-hander.
Akmal was more than a little unfortunate to lose his wicket as a leg-side delivery from Tim Bresnan ricocheted off the underside of his thigh-pad and back on to the stumps which it had originally been missing by a distance.
Asad Shafiq and Mohammad Yousuf looked to be steadying the ship only for the latter to be trapped leg before for 16 by a delivery from Anderson that moved sharply off the seam to catch Yousuf on the back foot.
While there was a suspicion that height could have been an issue, Hawkeye suggested the ball would have clipped the off bail to provide partial vindication of umpire Billy Doctrove's decision.
Shafiq and Alam then set about rebuilding the innings and did an admirable job as they put on 64 for the fourth wicket, but the partnership came to an end when the former attempted to loft Graeme Swann for a straight six but succeeded only in holing out to the retreating Morgan.
Umar Akmal could muster only a frantic 14 before he top-edged a short ball from the Bresnan to Swann at fine leg who took a comfortable catch.
Alam remained a much more composed presence and combined with his skipper Shahid Afridi to put on a useful sixth-wicket stand of 60 before he eventually perished as he drove to Andrew Strauss at extra cover off the bowling of Michael Yardy.
With Afridi joined at the crease by Abdul Razzaq, there was still cause for optimism for Pakistan - especially with Afridi going along at better than a run a ball.
But he was to gift his wicket to England for 34, carelessly run out after failing to ground his bat properly at the non-striker's end.
Razzaq weighed in with some typically lusty blows as he smashed three fours and a six in his quickfire 31 before becoming Stuart Broad's only victim to leave his side 227-8.
Gul (14) offered a little late resistance but, after the excellent Anderson had returned to claim his third wicket by trapping Saeed Ajmal in front, Bresnan nipped him to claim his third by dismantling Gul's castle.
In reply Davies and Strauss got England off to a brisk start with Davies carving Shoaib Akhtar through the covers to register successive fours in the first over.
Strauss quickly joined the party and, having pulled with authority and clipped Akhtar off his toes for four, then forced Razzaq through the off-side on the back foot to register three more rapid boundaries.
Davies had again found the rope off Razzaq with a pull of his own, but the bowler exacted quick revenge as he got the next ball through the left-hander's bat and pad to rock back the off stump.
Jonathan Trott (two) was quickly back in the pavilion although he had little to admonish himself for having been the victim of a quite superb inswinging yorker from Akhtar.
Strauss, looking in fine touch, remained a serene presence, but lost his third partner when Ravi Bopara advanced down the wicket to Ajmal attempting an expansive drive and succeeded only in nicking behind to leave England 77-3.
The England skipper notched his 23rd one-day international half-century off 48 balls with a single from Ajmal, but he would add only seven more as Gul returned for his second spell.
Having flicked the frustrated seamer for four down the leg-side, he was then bowled next ball via an inside edge to give Gul his first wicket.
Yardy then came and went; having already been dropped by Kamran Akmal behind the stumps, his scratchy innings of four was ended when an inswinging Gul delivery bagged him leg before.
But the ever-calm Morgan and Wright came together and, from a position of real difficulty, turned the match in the hosts' favour with England's highest-ever one-day sixth-wicket stand against Pakistan.
With a mixture of guile and controlled aggression they changed the momentum of the game and looked to have given their side a decisive advantage.
But Gul returned again to suddenly change all that with two wickets in four balls in the 39th over; Morgan was first to depart as he rather lazily lofted a half-volley to substitute Wahab Riaz at deep mid-wicket.
Three balls later Bresnan made his way off for a duck after having his middle stump dislodged and the same fate was to befall Broad in Gul's next over as Pakistan sensed victory with England at 207-8.
Gul's wonderful spell came to a fitting end as Swann drove his final delivery straight to Afridi at short cover who took a simple catch to put Pakistan on the brink.
It was left to the veteran Razzaq to wrap up the win as he emphatically bowled Anderson to spark jubilant Pakistan celebrations.
