After the excellent catch in the previous over, Kalumagage deals West Indies another blow with the big wicket of the well-set Shai Hope.
Hope goes the slog sweep over midwicket but misses the ball completely and is bowled after a fine knock of 75 from 46 balls, with four sixes and as many fours.
Kalumagage, who made pizzas for a living in Italy and had to quit his job to play in the T20 World Cup, has made a big impact with the ball in this tournament.
His trademark celebration is dedicated to his favourite football player Lautaro Martinez of Inter Milan, who also celebrates with his index fingers looking up.
Just two runs from the 16th over as Kalumagage continues to keep the scoring rate in check, having taken 1/16 in three overs.
