Wily spinner Saeed Ajmal took four wickets to fire Pakistan to a seven-wicket win over world number one South Africa in the first Test in Abu Dhabi on Thursday. (Match Scorecard)
The off-spinner (4-74) was superbly supported by left-arm paceman Junaid Khan (3-57) and fellow spinner Zulfiqar Babar (2-51) as South Africa collapsed to 232 in their second innings on the fourth day at Sheikh Zayed Stadium.
That left Pakistan to score 40 runs for their overall fourth win over South Africa and take a 1-0 lead in the two-match series.

Vernon Philander took 2-11 while Dale Steyn had 1-7.
Senior batsmen Younis Khan (28) and Misbah-ul Haq (nine) were left to see off the target with Pakistan captain deservedly hitting the winning six.
