2. Christopher Henry Gayle (West Indies): 16 sixes
The reigning Jamaican king, Christopher Henry Gayle became the first batsmen in history of World Cup cricket to score a double-century. Before this ruthlessly monstrous knock, the big man was horribly out of form. But, he turned his fortunes with this brilliant knock of 215 runs off just 147 balls at a strike rate of 146.25. In the 215 run knock against Zimbabwe at Canberra, he smacked 16 sixes and 10 boundaries. He also combined in a mammoth second-wicket partnership of 372 runs with his counterpart Marlon Samuels who scored 133 runs in the match. The duo shared the highest stand for any wicket in 44 years old history of ODI cricket. Gayle is ranked 2nd in our list.
