Phil Salt's 88 trumped Babar Azam's 87 for England to beat Pakistan in a Twenty20 and set up a series decider.
Both openers carried their bats through the sixth match, and Salt's extra ruthlessness was a big reason why England won by eight wickets to even the series 3-3.
They play the seventh and last match on Sunday at the same Gaddafi Stadium.
Salt smashed an unbeaten 88 off 41 balls, propelling a chasing England to 170-2 in just 14.3 overs.
Babar anchored Pakistan to 169-6 with an unbeaten 87 off 59 balls.
Salt's brutal batting in the powerplay led England to 82-1, the most runs ever conceded by Pakistan in the first six overs.
Alex Hales made 27 off 12 balls and added 55 runs with Salt. Then Dawid Malan and Ben Duckett combined with Salt to get England home with 33 balls to spare.
“Thought the way we batted in particular was outstanding,” England stand-in captain Moeen Ali said.
