Pak complete 3-0 whitewash over Zim
Pakistan, having been put into bat by the hosts captain Brendan Taylor, set a target of 270-5 with Zimbabwe making 242-9 in reply.
Pakistan captain Ul Haq said the policy of sending out a young and relatively inexperienced team had paid off.
He said: "This is all a good sign for the future of Pakistan cricket and from that viewpoint alone it was worth coming."
Pakistan, who had scrambled to a five run win in the opening match and took the second by 10 wickets, were always the dominant side.
