Merrick Bremner of South Africa birdied six of his first nine holes, shooting an 8-under 64 Thursday to tie the course record in the opening round of the South African Open.
He's two shots ahead of Sweden's Henrik Stenson and South Africa's Matthew Carvell at Serengeti Golf and Wildlife Estate on the outskirts of Johannesburg.
Former Masters champion Charl Schwartzel recovered from a double-bogey 5 on his third hole at the 12th for a 68. Former top-ranked player Martin Kaymer shot 70, while Branden Grace was even par.
Bremner consolidated his outstanding start with two more birdies on the back nine. His bogey-free round raised hopes of a first European Tour title at his home event.
