Afghanistan overcame late nerves in the closing overs to beat Pakistan by seven wickets in the second Twenty20 international on Sunday and take an unassailable 2-0 lead in the three-game series.

Needing 30 off the last three overs, and 22 from the last two, Najibullah Zadran and Mohammad Nabi hit a six each off pace bowler Naseem Shah in the penultimate over to reduce the target to five runs.

Pakistan's 130-6 in 20 overs was built around a sedate 57-ball 64 not out by all-rounder Imad Wasim -- his maiden T20I half century. This was Afghanistan's first bilateral T20I series against any of the top six teams.
