Chasing 196 runs to win, the SA team were restricted to 185/9.
The Proteas crashed in another shock defeat on Sunday night, settling for a one-all draw in their T20 International series against Ireland.
Having lost in a 2-1 defeat to Afghanistan in their ODI series in Sharjah the previous week, the SA team had bounced back with a convincing eight-wicket victory over Ireland in Abu Dhabi on Friday.
They had no response, however, to a magnificent century from Ross Adair which set up the Irish side for a 10-run win in Abu Dhabi to close out the weekend.
