<P> On 31 August 1968 , Garfield 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 at St Helen 's in Swansea . Nash was a seam bowler but decided to try his arm at spin bowling . This achievement was caught on film . </P>
