World Record for South Africa's AB de Villiers
With a good platform set by South Africa's opening batsmen, AB de Villiers came in to bat with the Proteas well placed at 247/1 and looking to be headed for a score of well over 300.
Under the circumstances, de Villiers was on the attack from ball one, hitting fours and sixes with seeming ease. He reached his 50 off only 16 balls, just beating the long-standing record set by Sanath Jayasuriya who reached 50 off 17 balls in a one day international against Pakistan way back in April 1996.
If de Villiers continues the way he's going, Corey Anderson's record for the fastest hundred, scored off 36 balls in January 2014 could be under threat too.
The Wanderers cricket ground is no stranger to records. South Africa completed the highest ever successful run chase at this ground in March 2006.
Edit: I'd barely finished writing this article before AB succeeded in breaking the record for the fastest hundred, reaching that milestone off only 31 balls.
