The first game on Saturday was abandoned because of rain and while grey skies threatened Sunday’s clash, Zimbabwe came through to take a 1-0 lead with one more match to come on Tuesday.
Ireland were put into bat by their hosts and scored 137-8 off their 20 overs, with Lorcan Tucker top scoring with 46 while Trevor Gwandu took 3-24 in his four overs.
Zimbabwe were in trouble as Craig Young (4-24) took out their top order cheaply but recovered from 64-5 at the halfway mark of their innings to go on and score 141-7 off 19.2 overs as Munyonga’s 43 runs off 30 deliveries proved a match-winning knock.
