This series started three weeks ago with the Boks needing a penalty after the hooter from Damian Willemse to narrowly beat a spirited Wales 29-23 after they were 18-3 down at halftime.
In that match, the Boks were lethargic in the first half but they launched a spirited fightback after the break to score three tries by Mbonambi, Malcolm Marx, Cheslin Kolbe.
With a 1-0 lead in the series, coach Jacques Nienaber tinkered with the team as he made 14 changes to the starting line-up for the second Test in Bloemfontein much to the displeasure of many people.
The Welsh Dragons took advantage to finally break their duck and record their first and narrow win (13-12) at the death on SA soil and most importantly to level the Test series.
But, the Boks prevailed with players like Ntuthuko Mchunu, Ruan Nortje, Deon Fourie, and Grant Williams having tasted international action.
