Not only is Schwartzel in great form he has a very good record at Leopard Creek having won the event in 2005 and been runner-up on several other occasions. His chances appear very good of a back to back victory.
Like Schwartzel, Louis Oosthuizen is in the middle of a rich vein of form at present recording six consecutive top tens in his last six starts
Three other South Africans, George Coetzee, Branden Grace and Thomas Aiken are also considered potential home grown winners.
No Australians are in the field, new European Tour recruit, Scott Arnold, missing by a start narrowly.
The event is the second of the 2013 European Tour schedule following last week's Nelson Mandela Championship presented by ISPS Handa.
