The T20 World Cup has reached its business end and a lot is riding on the remaining matches as various teams from the two groups try to make it to the semifinals.India’s crushing defeat at the hands of the Proteas in Ahmedabad on Sunday has left the title favourites on the edge. A lot depends on Thursday’s day game between South Africa and the West Indies. In case the Proteas prevail over the West Indies at the Narendra Modi Stadium in Ahmedabad, and India win their remaining two matches, they will be through in all likelihood.Likely scenariosIf South Africa defeat the Caribbean team and Zimbabwe and India win both their matches against Zimbabwe and the Windies, India will be through to the semis.If India win both their matches and the Proteas beat the Windies but lose to Zimbabwe, then also India will qualify.If India win both matches but South Africa lose to the West Indies but beat Zimbabwe, it will boil down to the Net Run Rate (NRR).In case India lose to Zimbabwe but win against the West Indies, the Windies win against South Africa and Zimbabwe beat the Proteas, the NRR will come into play.In case India lose to Zimbabwe but beat the Windies, the West Indies lose to Africa, South Africa beat Zimbabwe, again it will depend on the NRR.
