"We have decided to add Langeveldt as an additional player to the squad announced earlier," Cricket South Africa's president and national selection panel convener Gerald Majola said.
"We do not believe that we have all our bases covered at the moment in the bowling department," he explained.
"We have two major ICC [ Images ] tournaments coming up -- first the ICC World Twenty20 [ Images ] in the West Indies [ Images ] and then next year's ICC World Cup on the sub-continent -- and it is important that we explore all our options.
"Charl also brings much needed experience to our attack. He has played 64 matches while Dale Steyn [ Images ], Morne Morkel [ Images ] and Wayne Parnell [ Images ] have played only 67 matches between them. Johan Botha [ Images ] is the only other specialist bowler in the squad with 50 ODI appearances," Majola added.
