Richard Sterne heads a cluttered leaderboard at the Alfred Dunhill Championship after reaching the halfway stage in ten under par at Leopard Creek Golf Club in his native South Africa.
The South African is a stroke clear of four players after compiling a six under par second round 66 as he looks to become the first home winner of the event since Ernie Els three years ago.
Sterne`s compatriots Tyrone Mordt and Charl Schwartzel are nine under par along with England`s John E Morgan and Sweden`s Johan Edfors.
A strong home challenge is further boosted by Warren Abery at eight under, who is level with overnight joint leader Michael Jonzon.
Sterne started on the tenth and soon raced to six under for the day with birdies an eagle at the par five 13th and four straight birdies from the 14th.
His round threatened to unravel when he posted a triple bogey eight at the 18th, but he recovered with three birdies on the front nine.
Swede Edfors posted a three under par round of 69 to move to nine under at the halfway stage, and was joined by local favourites Mordt and Schwartzel.
Edfors had produced a bogey free 66 in the opening round but although he dropped shots at the seventh, 13th and 17th in his second round six birdies ensured he remained in contention for a first European Tour title since The Barclays Scottish Open in 2006.
Mordt started at the tenth tee and was level par for his round after nine holes.
But he fired six birdies - four of them on consecutive holes from the par three fifth - and a single bogey to post a front nine 30 on the way in.
Schwartzel - who won the event in 2005 - added a 67 to his opening 68, while Morgan carded five birdies and a single bogey on his way to a 68.
