The SA U18s beat a Namibian XV 27-16 at Outeniqua Park in George on Tuesday.
The hosts fielded a new-look starting line-up after 15 changes were made to the side that defeated the French U18s 25-5 in East London last Friday.
As a result the South Africans struggled to build momentum during the first half, but scored two tries through centre Patrick Howard and prop Tshepo Motale, which were converted by flyhalf Marais Schmidt.
The South Africans were heavily penalised in the first half by referee Lusanda Jam for various infringements at the breakdown. Namibia flyhalf Macho Prinsloo missed two penalty kicks in the first half, but managed to add two before the break to make it 14-6.
The hosts also struggled at scrum time and lost numerous lineouts off their own throw-ins.
The Namibians scored the first points of the second half when the hosts were penalised for offside play.
Schmidt, though, increased the SA U18s’ lead to 17-9 with a penalty kick after the Namibians were penalised for an infringement at the breakdown.
Free State U18 flyhalf Johan Goosen then kicked his first penalty kick of the afternoon after replacing Schmidt at No 10.
Goosen added his name to the try-scorers sheet after brilliant interplay by centres Paul Jordaan and captain William Small-Smith.
The Namibians, though, were last to score. Seven minutes from time lock Barend van Rensburg crashed his way over the try line to score his side’s only five-pointer of the match, which was converted by Prinsloo.
The SA U18s will play their third and final game against the England U18s on Friday at the Nelson Mandela Bay Stadium in PE (3pm kick-off).
