Six sixes in a six-ball over, cricket's fantasy overs.
On August 31, 1968, Gary Sobers became the first man to hit six sixes off a single six-ball over in first-class cricket. The over was bowled by Malcolm Nash in Nottinghamshire's first innings against Glamorgan in Swansea. Nash was a seam bowler but—somewhat rashly, as it turned out—decided to try his arm at spin bowling. This achievement was caught on film.
The feat was repeated by Ravi Shastri in 1984 , playing for Bombay against Baroda, in Bombay .
On March 16th, 2007, in a match between South Africa and the Netherlands at the ICC Cricket World Cup, Herschelle Gibbs became the first person to hit six sixes of an over in a One Day International match. The over was bowled by Dutch bowler Daan van Bunge.
On September 19th, 2007, in a match between England and India, Indian cricketer Yuvraj Singh hit six sixes off a single six-ball over in a Twenty20 international cricket match during the inaugural ICC Twenty20 world cup in Durban, South Africa. The bowler was Stuart Broad of England.
