Nazir toyed with the opposition bowlers, hitting them for four boundaries and three sixes. Hafeez gave him good support before they both got out to Abul Hasan in the 14th over.
The blazing innings came at the right time for Nazir, who scored his first international fifty since November 2009.
Both teams struggled with bowl as it was evident during the Bangladesh innings. Shakib made the Pakistani bowlers pay for their mistakes and played stokes all over the park. He struck 11 delightful fours and a couple of maximums.
