England 199 for 5 (Morgan 66, Malan 54*, Bairstow 44, Sahdab 3-34) beat Pakistan 195 for 4 (Hafeez 69, Babar 56, Fakhar 36) by five wickets
Manchester: England brilliantly chased 196 to beat Pakistan by five wickets in the second Twenty20 international at Emirates Old Trafford, Manchester on Sunday.
Captain Eoin Morgan smashed a 33-ball 66 and Dawid Malan was 55 not out as England won with five balls to spare.
The pair put on 112 from 62 deliveries after England had lost opener Jonny Bairstow and Tom Banton in successive balls to leg-spinner Shadab Khan.
With 18 needed England briefly stuttered, losing Morgan and Moeen Ali in the space of six balls, but the composed Malan saw England home.
It was another fine batting performance from England's white-ball outfit - the highest chase by any side against Pakistan in T20s.
It also made up for a ragged bowling performance which saw Mohammad Hafeez propel Pakistan to their total with a 69 from 36 balls.
England, who have won their past five T20 series, go into Tuesday's finale knowing they will at least draw this series.
England will be concerned that Banton's departure sparked the loss of four wickets for 14 runs in 19 balls before the stoppage.
Before that, opener Jonny Bairstow was out for 2 and Dawid Malan made a run-a-ball 23 after Pakistan won the toss and decided to field first under floodlights below gloomy skies.
England had scored just 34-1 after six overs, the team's lowest powerplay total since the 2016 World Twenty20 final.
Imad Wasim (2-31) and Shadab Khan (2-33) were Pakistan's best bowlers in Manchester, where there were no spectators because of coronavirus restrictions.
The other matches in the series are on Sunday and Tuesday. England won a rain-affected test series 1-0.
