Spin from both ends as Varun Chakravarthy comes into the attack. Buttler again takes a single first ball to hand the strike back to Duckett.
Duckett watchfully defends the second ball and reverse sweeps the next ball for a single.
Another single for Buttler before Duckett is unable to get a run off the last two balls.
A superb start for the in-form Chakravarthy as he concedes just three singles in his first over despite bowling in the Powerplay.
England race to 52/1 in six overs, with Duckett on 39 from 18 balls and Buttler on eight from 11 balls.
