Zimbabwe beat Pakistan by 80 runs in a rain-shortened one-day international at Queens Sports Club in Bulawayo on Sunday.
The home team scored 205 all out after 40.2 overs thanks mainly to a 62-run eighth-wicket stand between Richard Ngarava (48) and Sikandar Raza (39).
Pakistan, reeling from a 3-0 ODI series loss to Australia this week, were struggling at 60-6 after 21 overs when torrential rain, thunder and lightning halted play in the southern city.
After a delay of several hours, the match was called off and the Duckworth Lewis Stern method applied, giving Zimbabwe a convincing victory.
The teams meet again on Tuesday and Thursday before playing a three Twenty20 internationals. Pakistan then travel to South Africa for an all-format tour.
