Zimbabwe got good confidence lately by playing against bagladesh india and Australia in small grounds/unknown grounds of Australia so it's not surprised that they do good
But slowly looking Indian group can be became group of death
Agree that Ireland played well recently, but recently Zimbabwe also won ODI vs full strength Australia in Australia and they have better T20I rank than Ireland.
Netherlands beat Namibia by 5 wickets. Nothing much to say about that match. Last two overs were fun to watch though. Namibia was very close to win. They have made Group A interesting.
