Home favourite Thomas Aiken moved into contention with a strong start to his second round at the Alfred Dunhill Championship.
The South African, who captured the last of his three European Tour titles on home soil almost six years ago, was two under through 12 holes at Leopard Creek Country Club.
After turning in a one under par 36, Aiken made a gain at the long second to reach six under par.
That left him tied for second with Spain’s Pablo Larrazábal and England’s Garrick Porteous on six under par.
Both Larrazábal and Porteous were among the later starters, as was overnight leader Wil Besseling, whose seven under 65 on the opening day had given him a one shot lead.
Also climbing the leaderboard was English Qualifying School graduate Marcus Armitage, who at two under through 14 holes was up into a share of sixth on four under.
