Ajmal Shahzad and Chris Jordan each claimed three wickets as the England Performance Programme squad sealed a 75-run win over Nashua Titans with a day to spare.
The tourists declared their second innings at 155-4 at lunch on the third day to set the Titans a target of 345 in five sessions on a good wicket in Pretoria.
The EPP bowling attack ensured the match did not head into a fourth day, however, with pacemen Shahzad and Jordan to the fore.
The Titans began the run chase well enough, reaching 44 before the first wicket fell in the 10th over.
The home side's middle order, led by Francois du Plessis, all scored positively, with three players reaching the 40s, and the match was evenly balanced in mid-afternoon with the hosts on 200-5.
But Surrey seamer Jordan claimed two quick wickets to break their resistance and Kent off-spinner James Tredwell also weighed in with two wickets.
And it was Yorkshire fast bowler Shahzad who mopped up the tail with the last wicket after EPP skipper Andrew Gale had claimed an extra 30 minutes.
Earlier, the EPP had added 111 runs to their overnight position of 44-1 during the morning session, Michael Carberry leading the way with 76.
