South Africa benefited from another Pakistan batting collapse to win the second Twenty20 international by six runs in Dubai and claim a 2-0 series win.
The Proteas managed to set a challenging total of 150-5 from their 20 overs, but Pakistan looked well placed to level the series until they lost six wickets for just 43 runs to come up six runs short at 144-9 in 20 overs.
After winning the first game in the series by nine wickets, South Africa produced another solid outing with the bat thanks to a second-wicket stand of 78 by Faf Du Plessis and Hashim Amla.
Du Plessis made his unbeaten 58 from just 48 balls with three sixes while Amla added 48 in only 41 deliveries with three fours and two maximums.
Pakistan off-spinner Saeed Ajmal took 3-25 while paceman Sohail Tanvir chipped in with 2-21 as the pick of the bowlers for the nominated home side.
A 38-run opening partnership for Pakistan from Ahmed Shehzad (21) and Nasir Jamshed (19) put them on a solid platform, but wickets soon started tumbling.
Sohaib Maqsood produced the only other meaningful offering with his top score of 37 as Wayne Parnell finished with 3-25 while Imran Tahir took 2-21 and Dale Steyn chipped in with 2-20.
