Ali Rizvi, 23, is yet another product of the Pakistan A tour to England this summer, where his leg-spin claimed 28 wickets.
Rizvi joins fellow leg- spinner Mushtaq Ahmed and off-spinner Saqlain Mushtaq in the 13-man party which also includes Wasim Akram, now deemed to be fit by the selectors.
The eleven who played in the first Test are all retained. Waqar Younis is still troubled by a bruised heel but has been having acupuncture to overcome the problem.
Allan Donald, nursing a hamstring injury, is South Africa's latest fitness worry.
