Nottinghamshire had been chasing quick runs all morning. By the early afternoon Sobers, the West Indies captain and the world's most complete cricketer, had moved into the seventies. Glamorgan captain Tony Lewis, hoping to hurry the declaration, asked Nash — primarily a left-arm seamer — to bowl slow left-arm round the wicket. Nash agreed. Sobers, six down to his last recognised batsman Brian Bolus, decided to attack.
Ball one: pitched up, swung high over square leg into a garden behind the boundary. Six. Ball two: same length, same shot, same garden. Six. Ball three: full, driven over long-off into the pavilion. Six. Ball four: short, pulled hard over midwicket onto the road. Six. Ball five: an attempted yorker, lofted straight; Roger Davis at long-off caught it cleanly above his head and tumbled backwards over the boundary rope. Under the law clarified by MCC earlier in 1968, that counted as six. Ball six: the over's last delivery, pitched up, swung over midwicket and out of the ground onto Gorse Lane. Six.
Sobers had taken 36 from one over — the first ever in any form of first-class or Test cricket. He declared shortly afterward on 308 for 5 with his own innings unbeaten on 76. Nash, 23 years old, accepted his place in the record books with grace; he later said he had bowled exactly the deliveries he intended to and Sobers had simply been better. The pair remained on cordial terms until Nash's death in 2008.
The BBC camera crew had been at the ground primarily to test new equipment and were filming intermittently. They captured the fifth and sixth sixes. The footage — accompanied by Wilf Wooller's exclamation "and he's done it! He has done it! He's hit six sixes!" — became one of the most replayed clips in cricket television.
