Kieran Powell is a powerful left-hand opening batsman who began playing cricket when he was eight. Both he and his brother, Alan, have represented the Leewards Islands at the Under-15 and U-19 level while Kieran went on to break into the West Indies' U-19 squad.

He played for Nevis in the 2006 Stanford 20/20 and scored 26 off 16 balls against St. Kitts and 21 off 9 balls against Antigua. He brought his attacking game to the 2008 U-19 World Cup in Malaysia and entertained with his aggressive stroke-play, which brought him 253 runs at a strike-rate of 124. He was part of a depleted West Indies ODI side for the home series against Bangladesh the following year, where he suffered the ignominy of being dismissed for a golden duck on debut.
