Beaten by New Zealand in their previous outing, a win was imperative today for the Lankans who rode on Jayawardene's masterly 64-ball 100 - fourth century in the short history of Twenty20 Internationals - to post 173 for seven.
Zimbabwe's chase ran into a rain-interruption after the first over from Ajantha Mendis. Play did resume after 66 minutes with the minnows chasing a revised victory target of 104 runs from 11 overs but another weather-disruption greeted them four overs later when they were 29 for one.
