Michael Leask and George Munsey starred as Scotland beat World Cup debutants Italy by 73 runs at Eden Gardens.
Munsey – dropped on 40 – blasted 84 as Scotland set 207-4 off their 20 overs, helped by Leask taking 22 from the final five balls of the innings.
Leask carried that momentum into the field, dismissing Italian opener Justin Mosca first ball as Munsey took an excellent diving catch to his right.
Despite a 73-run partnership between brothers Ben and Harry Manenti, Italy were always behind the rate and once they were removed, Scotland skittled the tail for a comfortable win.
With captain Wayne Madsen unable to bat having dislocated his shoulder fielding, Italy were bowled out for 134 in 16.4 overs.
Leask finished with magnificent figures of 4-17, while Mark Watt chipped in with 2-24 as Munsey pouched four catches.
Scotland – with one win from two – are next in action against England on Saturday, while Italy face Nepal on Thursday.
