Zimbabwe beat Namibia by 86 runs
Namibia concede defeat after failing to answer Zimbabwe's record total in a rain-affected match at Harare.
Rain forced the chasing side to call it a day, but not before the Zimbabwe had bowled the required 25 overs to seal a revised 86-run win.
Earlier, Craig Wishart's unbeaten 172 helped the World Cup hosts to an awesome total of 340-2.
It was Zimbabwe's highest score in a one-day international, beating their 325-6 against Kenya in Dhaka four years ago.
Namibia's target was revised, under the Duckworth-Lewis system, as heavy rain fell during the afternoon, but a second downpour caused the match to be abandoned.
With the visitors scoring well below the required run-rate, especially after the dismissal of flamboyant batsman Jan-Berry Burger, the result was never in doubt
