Dubai - Jacques Kallis and Hashim Amla each approached a century Monday as they helped South Africa build up a big lead on the fourth day of the first Test against Pakistan at the Dubai Stadium.
At lunch, Kallis was unbeaten on 90 and Amla unbeaten on 85 as South Africa reached 239-2 in their second innings for an overall lead of 371 runs, posing real problems for Pakistan.
Both Kallis and Amla dominated the bowling to help South Africa add 100 runs in the morning session without being separated as Pakistan used both their spinners as well as paceman Umar Gul.
Kallis was more aggressive, having so far hit seven boundaries and two sixes during his 156-ball knock. Amla ably supported his senior partner, hitting eight boundaries off 179 deliveries.
The Kallis-Amla stand for the third wicket has so far yielded 163 runs.
Resuming at 139-2, South Africa continued to build their lead through Amla and Kallis as none of the Pakistani bowlers could create any problems for the batsmen.
Amla was the first to reach his half-century, pushing paceman Gul for a single to reach the landmark. He hit five boundaries for his 16th Test half-century.
Kallis also completed his second half-century of the match - the 55th of his career - with a single off spinner Abdul Rehman, before cutting loose, hitting Saeed Ajmal for two boundaries and a six over long-on.
