Chris Gayle (138 balls- final score 215 off 147)
The self-proclaimed Universe Boss has done several awe-inspiring things on a cricket - before his double ton in 2015, he had already hit two triple-hundreds in Tests and several T20 centuries. It wasn't hugely surprising then when he breached the 200-run barrier in the 2015 World Cup, against minnows Zimbabwe.
Always carrying a huge appetite for runs, Gayle combined with Marlon Samuels for a record 372-run partnership, breaking a 20-month drought where he hadn't scored a century.
He became the first non-Indian batsman to score a double-century in ODIs, but was soon joined by Martin Guptill, who bettered his score with a 237 against the West Indies itself in the quarter-finals of the same tournament.
