4. Sourav Ganguly (104 balls):

Former India skipper Sourav Ganguly scored an uncharacteristic fifty against Bangladesh during the disastrous day for Indian cricket in the 2007 World Cup. With wickets falling at one end, Ganguly never found the situation to play his usual shots and scored his fifty in 104 balls. His knock finally came to an end on 66 off 129 balls.
India could manage only 191 on that fateful afternoon, as Bangladesh chased down the score to register its first and only win till date on their illustrious opponents in World Cup.
