At one stage in the second spell SA Schools had shot out to a 20-8 lead and looking comfortable but a resilient Wales rallied well and forced their way back into the game with a converted try by Josh MacLeod.
Wales then added another try nine minutes later through prop Leon Brown, but an unsuccessful conversion left the scores level at 20-20. Both teams threw the kitchen sink at each other but neither side was able to make the crucial breakthrough with both teams forced to settle for a draw.
Wales began the game brightly, applying early pressure on SA Schools A as they retained possession and strung together phases, but could only muster a penalty to their credit as they battled to penetrate the defence.
The hosts, however, hit back with back-to-back tries within two minutes by flanker Phillip Krause and flyhalf Bader Pretorius after fantastic breaks on attack for a 10-3 lead.
Wales fought back with intent with their strong forwards and managed to force their way over the tryline to reduce the gap on the scoreboard to 10-8 before the break.
The SA Schools A team came out firing in the second half with flanker Kwanda Dimaza dodging his way around a defender and diving over the try line to extend their lead to 17-8. They added a penalty to stretch their lead to 20-8 before Wales hit back but they ran out of time to complete the series with a win, loss and a draw.
