Boeta Dippenaar hit a patient 74 to set the foundation for South Africa's seven wicket-win over Pakistan on Sunday to clinch the fifth and final one-day international and take the series 3-2.
It was South Africa's third win in a row and came in the absence of skipper Graeme Smith and Andrew Hall, both suspended for breaching the ICC's code of conduct in the second match at Lahore.
Chasing 193 to win after a disciplined bowling performance, Dippenaar, whose runs came from 125 balls, shared in two half-century stands with Herschelle Gibbs (34) and Jacques Kallis (40).
He added 75 with Gibbs, who was smartly stumped by Rashid Latif off leg spinner Danish Kaneria, then another 93 from 125 balls with Kallis.
The in-form Dippenaar, with knocks of 110 and 58 earlier in the series, fell leg before in the 40th over to paceman Mohammad Sami but Jacques Rudolph (13) and Neil McKenzie (9) guided the tourists home with 4.1 overs to spare.
Stand-in South Africa skipper Mark Boucher, leading the side for the first time in a one-day international, did a good job of marshalling his bowlers as Pakistan lost their first five wickets for 80 runs.
Abdul Razzaq with 38, Rashid Latif 25, Shoaib Malik 20 from 29 balls and Mohammad Sami 22 from 30 put together vital partnerships in the second half of the innings to add 112 runs.
Shaun Pollock took three for 33 and there were two wickets apiece for Robin Peterson and Andre Nel.
