Abdul Razzaq smashed 46 from 18 balls to lead Pakistan past England by four wickets and split the two-match Twenty20 series on Saturday.
Razzaq finished the match with his fifth six, a blast over long on off newcomer Ajmal Shazhad.
England totaled 148-6 and Pakistan made 149-6 with an over to spare at Dubai International Cricket Stadium.
England won by seven wickets the day before.
"England had put up a good total. We did not played well in the middle. But Razzaq was awesome," Pakistan captain Shoaib Malik said. "It was great batting and it was nice to see him the way he batted.
"We needed this win. We should have our confidence back now. But all credit to Razzaq, he was simply too good."
Razzaq, who went in at 78-5 after 13 overs, backed up Umar Akmal (36) and Fawad Alam (28) with a brilliant allround effort. He also bowled a tight spell of four overs, conceding only 17 runs even as Kevin Pietersen continued his good form.
Pietersen, who hit 43 not out on Friday, made another aggressive 62 and with Jonathan Trott (39) racked 98 from 12.2 overs for the second wicket. But a late flurry of wickets allowed Pakistan to stifle England.
Trott was run out going for a needless run just when both batsmen were set to cash in on the platform they built. Once he left in the 17th over, Pietersen, who brought up his half-century in 29 balls with four boundaries and two sixes, followed him in the next as he was trapped leg before to Saeed Ajmal.
Umar Gul went for 17 runs in the penultimate over but Yasir Arafat just missed a hat trick in the last.
England captain Paul Collingwood considered the series good preparation for the World Twenty20 in West Indies starting from April 30.

"We are in a good groove," he said. "The batsmen have been giving us good totals to defend. KP (Pietersen) was brilliant and is back in form now so that is a positive for us. It was a good series. We will take this form and go into the World Cup with confidence."
Pakistan's chase started badly with both openers, Imran Nazir and Imran Farhat, gone in the first over to Shahzad on debut.
Umar Akmal and Malik settled in but Graeme Swann struck in the sixth over to improve his reputation as a breakthrough bowler.
Malik lost his balance trying to play a legside delivery and was ruled out for 13 after a long deliberation by the TV umpire.
Shahid Afridi, playing his first match after a two-game ban for ball-tampering, also did not last long, his slog sweep shot pouched by Eoin Morgan at deep mid-wicket for 8 at 64-4.
Akmal was the fifth wicket for England, but that brought in Razzaq to partner Alam, and they turned the momentum completely.
Razzaq blasted Collingwood for two sixes off successive balls over midwicket to open his scoring in the 14th over.
Alam's batting was not convincing but the pair kept the runs going.

Razzaq hit another six off Luke Wright with an impressive scoop over the bowler's head.
Alam lived dangerously as he swung wildly and eventually fell to Morgan at deep backward square leg.
When Pakistan needed 17 from the last two overs, Razzaq wasted no time with a pair of sixes in the penultimate over.
