AB de Villiers created history on Sunday with a South African record 278 that put the Proteas in control on the second day of second Test against Pakistan.
De Villiers resumed the day at 120 and continued to plunder the Pakistan bowling, smashing a brilliant double-century as South Africa declared at 584-9 in Abu Dhabi.
Proteas captain Graeme Smith's declaration allowed his side to bowl 18 overs, with Dale Steyn snaring a victim before bad light ended play with Pakistan 59-1.
But the headlines belonged to de Villiers who stunned the crowd with another superb day's batting.
Resuming at 311-5, de Villiers and Mark Boucher struggled for runs early as Pakistan bowled tightly in the early stages.
Boucher added just 19 to his overnight score when he was dismissed for 45 by 31-year-old debutant Tanvir Ahmed, who captured his fifth wicket by clean bowling the South African wicketkeeper.
De Villiers saw Boucher's dismissal as time to begin the big hitting as he crunched several boundaries during the opening session.
The likes of Johan Botha (12), Steyn (27) and Paul Harris (19) played second fiddle to the 26-year-old as he brought up his double-century with a boundary off the bowling of Umar Gul.
After Harris' dismissal, de Villiers was joined at the crease by Morne Morkel as the pair broke another South African record, adding an unbeaten 107 for the 10th wicket.
They broke the 81-year record of 103 and took the score to 584 before de Villiers passed Smith's national record of 277, achieved in England at Birmingham in 2003.
A single off Gul took de Villiers to 278 before Smith promptly closed the innings and gave Pakistan the difficult task of facing 18 overs before stumps.
Tanvir (6-120) did not receive enough support from the likes of Gul and Mohammad Sami.
Abdur Rehman (2-150) and Mohammad Hafeez (1-58) were the only other wicket-takers.
After a mammoth 153-over stint in the field, Pakistan's batsman were clearly tired and Hafeez (two) was unable to focus himself, falling leg before wicket to paceman Steyn.
On a batsman-friendly pitch, Taufeeq Umar (16 not out) and Azhar Ali (34 not out) guided Misbah-ul-Haq's side to stumps but they will return on day three a whopping 525 runs in arrears with nine wickets remaining.
