Swede Henrik Stensen is one round away from taking out the Nedbank Golf Challenge at Sun City, South Africa. Only disaster could halt Stenson s charge toward the title after another impressive performance on Saturday (SA time). Stenson carded a seven-under-par 65 to streak to an eight stroke lead over fellow Swede Robert Karlson who is nine under the card after a well-constructed 67 on day three. South African Rory Sabbatini is a further three strokes adrift after a 67 while American Kenny Perry is at five under after a third-round 68. KJ Choi had a difficult round, shooting a one-over-par 73 to be tied in equal fifth place with Englishman Lee Westwood.
