Damien McGrane made a flying start to his second round at the South African Open Championship to move into a one shot lead at Pearl Valley Golf Estates.
The Irishman started on the tenth tee and picked up six birdies on the way out for a six under par 30 on the back nine.
He added another birdie at the first to reach seven under for the day and nine under for the tournament.
That was enough for a one stroke lead over first round leader Fabrizio Zanotti - who was not due out until the afternoon - and Lee Westwood.
Westwood built on his opening 66 with three birdies and a single bogey in his first 11 holes to reach eight under for the tournament.
South Africans have won this event seven years in a row and two were mounting their challenge during the early stages of the second round.
Thomas Aiken and Charl Schwartzel were both seven under, through 12 and ten holes respectively, to lie level with Swede Oskar Henningsson who was yet to tee off.
